What Giant vise is the Strongest? 7000 dollar vises.

get nervous here there we go oh today in this video I'm going to be testing the world's best bench vice and I call it the hardtail its sole design purpose was to be the strongest most powerful bench vice ever made it's taken me over four years of prototyping and testing to get it to this point throughout my testing I've learned that all vices aren't created equal some are better than others I'm gonna compare the hardtail vice to the most popular vices that have ever made at the top for decades what I would like to know is what happens if they take a hard impact and how many times how strong can they clamp and how heavy are they and does the swivel base actually work under stress these are the answers that I'm on a journey to find the first advice I want to compare the hardtail to is the legendary Wilton 600s the Wilton company has been manufacturing for a long time and they started in 1941. the company got its name from the cross streets that the original manufacturing plant was located rightwood and Wilton Avenue in Chicago Illinois Wilton has made all sorts of different sizes and styles of vices over the years the 600s is now their current largest Vice that they make weighing in at 146 pounds and made from strong ductile iron having six inch jaws and a 10 inch maximum opening all of this costing me 2107 to put that into perspective that's 14.38 cents per pound one thing we don't know is its clamping Force we're gonna have to figure that out for ourselves so you're probably wondering why I'm not testing the Big Brother the 800s for this test well it's been discontinued unfortunately and as much as I would love to test it up against the hardtail it's only fair to compare what vices are available for sale today the next Vice we're going to talk about is the Morgan 8 Vice established in Chicago in 1891 and selling devices at the World's Fair they quickly became an established Vice manufacturer but the same Vice design is still in production to this day I weighed this giant Vice at 203 pounds and 14 ounces constructed from ductile iron it has eight inch jaws and opens up to over 11 inches Morgan also doesn't reveal how much clamping force it can take but what they do want is three thousand forty two dollars that's 14.98 per pound now let's talk about my Fireball hardtail I built this Vice for you the professional the guy who breaks things likes to smash and hit things with a hammer and to have the highest clamping force of any Vice ever sold this thing is built to be indestructible it does this because it weighs 260 pounds has six and a half inch wide jaws and as far as I know is the largest opening bench vice at 14 inches currently this Vise costs eighteen hundred dollars that puts this at 6.93 per pound I still need to find out what its maximum clamping force is and how much abuse it can take versus the others so if you're a vice lover like myself you're probably going to want to turn away because all three of these vices are going to get destroyed today we need to learn which one of these vices is actually Superior even though they're designed to do the same thing they all have different designs so let me walk you through what's special about each Vise one of the things I noticed when I was testing vices is just how weak they are when they're at their Max opening the dynamic jaw likes to bend down when they're put under high load and you can see this in some of these previous tests so let's take a look at these three vices to see what's going to prevent the dynamic jaw from bending the Wilton has chosen to keep the vice as compact as possible the static jaw of the Wilton measures 14 inches long when the vices opened up to 10 inches that only leaves 4 inches left inside of the body to keep it from bending I suppose there's a sacrifice a little bit of strength for a much smaller footprint let's take a look at the Morgan Vice it has a neat feature called a chin it's a large shelf that sticks out past the jaw when it's opened up to its 11 inch Max opening it gets 10 inches of support from the static jaw under high load Vice Jaws can get out of alignment so the more support underneath that jaw the better now let's take a look at the hardtail I'm going for maximum strength with this design to ensure that the jaw wasn't going to bend on the hardtail I made sure there was 14 plus inches of support with the static jaw I did this by oversizing the dynamic jaw body and adding a huge chin underneath that jaw I also made sure that it projected several inches out past that static jaw all that mass is going to help these Jaws stay parallel even at the highest clamping forces one location that vices like to fail when they're abused is right here on the dynamic jaw this is a high stress area so let's take a look to see how these three Vice designs handle it we have a round tube hooked into a casting I think this is pressed in and this is going to be an interesting termination point when we go to put this thing under some serious load and if we look at the Morgan they actually reduce this point for Machining purposes in manufacturing they don't want the cutter to have a nice termination point this could be a potential failure so that's also strange the fireball has these nice big wide cheeks that are actually over the top kind of like gussets they are not perpendicular to the top they're at a 45 degree a lot of mass right here because the Vise is designed to hold things it's not uncommon to hit whatever we're holding with a hammer and this can put a lot of stress on the Jaws especially hit with a downward Force so let's look at all three jaw designs to see how they'd handle this problem the Wilton has some pretty good Jaws inch and a half by one inch wide jaws and it's got some decent meat underneath there three quarters of an inch at its thickest Point let's pull out this screw these are all the little details that you can't really see when you go to buy a vise so I've got a 3 8 Fastener there and Morgan has little tiny thin half inch mild steel Jaws inch and a half tall by only a half of an inch wide maybe a half of an inch of casting underneath and the only thing that they're held in by are these little tiny quarter 20 screws there's only three of them go into here that's like that the hardtail has two hooks the jaw is hooked over the top giving you all this meat plus this big area down here the jaw itself is super heavy duty we're talking one inch thick inch and three quarter tall solid steel jaws and it also has half inch socket-headed cap screws holding the Jaws on two large great eight Fasteners and there they are all together that's what holds the Jaws on let's take a look at the dynamic jaw the nut and the screw since all three vices have taken a different design approach let's look at the Wilton first they have chosen a round Dynamic jaw and in my opinion they chose this for the ease of manufacturing they can put the dynamic jaw on the lathe and turn it round the matching hole can easily be drilled out with a big drill bit this makes the whole manufacturing process very simple the trade-off though is strength unfortunately round isn't the best at resisting the bending forces the device sometimes has to cope with but from a manufacturing perspective I do see why they chose this design what keeps the shaft from twisting is this keyway any side Force any side hitting on that Dynamic jaw is going to be putting a lot of load on that it's a good design because you can get a lot of precision with that the body of the Wilton like maybe three quarters of an inch now let's take a closer look at the dynamic jaw on the Morgan Vice the first thing we're going to notice on the dynamic jot is that it's rectangular and that's cool because rectangles are strong the problem with the rectangle is that it's more expensive to manufacture which means you can't put it into a lathe it requires a milling machine this generally requires more setup time which adds the extra cost and another thing to note that this rectangle actually has one open side now they left this side open for the nut and we'll talk about that a little bit later but it does weaken the shape and I have seen these crack before now let's talk about the static job we need a rectangular hole to match and this requires a specialty tool called a brooch these can be very expensive because they're equipped with a whole bunch of little cutting teeth each tooth is removing a couple thousandths of an inch at a time and if done correctly you get a perfectly matched rectangular shaped hole the Morgan also has these pads on the inside that keep this slide concentric in the bore it looks like they messed up the castings and this hole was broached too big it looks like they came in here with a welder and put some weld bead on the top there so that it will pick up some of the clearance the Morgan feels like it's a good inch thick this is a raised section right there when you get past that it's only an inch thick let's take a look at the dynamic jaw on the hardtail Vise because the most important thing on this device is strength I decided to go with a fully boxed Dynamic jaw and I'm able to do this because of the nut location which we'll talk about a little bit later the rectangular shape still needs to be milled and broached all at the same time raising the cost mathematically the box is the best design but we'll only be able to tell when we really put this Vise through the stress test so I look forward to that so the way the fireball keeps its concentricity when this jaw is fully extended this way rides in this tongue up here and keeps it from moving side to side and the fireball is also an inch in thickness the one last major component we need to look at is the nut let's take a peek inside the Wilton to see how the net works there is the Wilton nut Wilton uses a straight pull design which means one end of the Vise the nut is attached and that the other the spindle this puts the nut and the screw in tension and that makes it really strong they're able to do this because of that round hole that they put into the dynamic jaw that way the screw can pass right through the center of it this design also keeps the screw clean and in a shop environment that's really important I really like it it's a pretty good design the Wilton uses four threads per inch inch and a sixteenth diameter shaft pretty interesting let's take a look inside the Morgan Vice they've decided to go with a very typical or standard nut design the nut gets wedged into the base of the static jaw the spindle and the nut create a L shape and because of this the nut likes to jam or tilt under high loads when the nut tilts it puts some strain on the spindle causing it to Bow this will make the spindle hard to turn adding a lot of friction even though I'm not a big fan of this design this is a real good way for manufacturers to save some money the Morgan uses four threads per inch inch and a quarter so this is the Morgan nut this is a really common failure point it likes to snap off when you're clamping hard see how it wants to bind the nuts only supported by one side it's not pulling evenly on it I'm a little disappointed it looks like this hole is drilled off center or the casting is just thin a lot of backlash in there as you can see it's attached to this pin right here it keeps it from sliding back and forth but look at all that slop in there let's take a peek inside the hardtail like the Wilton the hardtail uses that straight pull screw design and like the Wilton because of its hollow center inside the dynamic jaw we're able to connect the back of the hardtail and the end of the spindle together creating a really straight line pole with the screw when I do the ultimate clamp force test I think this is going to make a big difference so the fireball uses a five threads per inch also uses inch and a quarter nut comes out the back really thick 3 8 wall and there's three inches of thread engagement which one would you rather have let's take a look at how the spindle transmits its clamping Force into the device Jaws when we look at the Wilton the Wilton just has this horseshoe plate and that's what removes the backlash forward and backwards and they've got that fit pretty tight so it's metal on metal grinding action when you go to tighten and loosen it the Morgan has no thrust bearings it just has a wear washer so that this knob doesn't rub the casting let's take a look at its build quality a lot of slop in there it uses this locking collar to adjust that slop how much there is back and forth now the fireball uses thrust bearings this is going to greatly reduce the friction has a Thrust bearing on one side and a Thrust bearing on the inside this spring here is for removing backlash and it keeps this connection nice and tight another common problem that I see in vices is the swivel base the swivel base has a really hard job it needs to Pivot smoothly with the release of two knobs and then permanently lock the Vise back down when a new location has been selected all three vices here tackle this problem a little bit differently so let's take a look let's check out the Wilton swivel base Wilton puts the handle really close to the body it's almost touching and the first thing I'm noticing is the crimp on the Wilton is so sharp I can cut myself with that Wilton has chosen to use a nut instead of a stud so Wilton uses a really weird bolt pattern not symmetrical six in some blah blah blah blah blah number and seven and some blah blah blah blah blah number I don't know why they just can't make it a standard number but it's awfully small probably not going to do well in the strength test when we go to start hammering on this thing now let's dissect the wilt in here all right Wilton swivel base is quite complex this thing is hollow and thin I don't know if you can hear that kind of feels cheap in your hand that's maybe 3 8 of an inch thick but they do have something that I like these little ridges inside these little teeth those correspond with these teeth on this nut and it makes that grip but realistically the only thing holding is this little section right there if this were to snap off this little tab this thing's coming apart that's going to be the first point of failure just a prediction we're gonna find out the base itself of the casting looks really good it's machined pretty heavy duty and fairly thick let's take a look at the Morgan swivel base here the handle comes really close to the body there and when you're trying to tighten it and you get it tight and then you try to slide it over now you can't get your fingers in there that's really frustrating so they use a nut instead of a bolt handle length it's pretty short pretty heavy duty so the Morgan does something strange it uses three holes instead of four 11 inches diagonal by eight that's a pretty good pin there that the vice swivels on I like that oh man that is the nut so this is all cast iron this whole thing let's take a closer look inside this casting Morgan has chosen a flat bottom T Groove this means you have two flat surfaces that need to resist the twisting force when we look at the casting you can see that there's an inside corner there that's going to make a really high stress concentrated area not only on the swivel base but the nut also let's see how big this sucker is feels pretty solid this lip is deceiving the wall thickness feels like it's only maybe 3 8 of an inch just kind of has this big heavy thickened Edge overall you're looking at nine inches and Center to center six and a half let's take apart the fireball swivel base the distance between the center line of this adjustment bolt to the body is quite generous like an inch and a half so it's really easy to get your hands in here if you have gloves look how cool that bolt is there's two of them really nice long generous handles handle a little thicker on the Wilton than the Morgan and then there's the fireball handle I know which one I'd want to hang on to so the fireball base is 12 by 8 on a perfect rectangular grid pattern let's pull the fireball apart and look and see what's inside the swivel base pivots on this big pin and the wall thickness here is half of an inch thick by these really heavy duty feet that are also one inch thick supported by this really cool gusset this right in the center is solid and what holds the swivel in place is the swivel nuts now if you look at them they're built on a taper so why did I choose a tapered nut well there's some serious advantages to this first is that the nut is able to transfer the load across a much larger surface area to both sides of the channel inside the swivel base when the nut starts to get drawn up inside the wedge it transfers the load much more evenly inside the channel of the swivel base this is going to prevent the casting from getting fatigue and cracking if you've ever used a vise that kept spinning on you no matter how hard you crank the handle while this wedge will help that you don't need a lot of force to get the vice to stay in place let's take a look at thickness here's the fireball nut here's the Morgan nut if you look at that diameter of the swivel base that's also effective on how much effort it takes to turn and this is a really big swivel base 10 inches eight inches on the center line the base that the fireball swivels on is a piece of solid cast iron one inch thick out here on the edges so I got devices all back together again and there's one little fun test I want to do and that's just to see how far can it open in 10 seconds the hardtail is at a disadvantage because it has one more thread per inch so let's give it a shot Wilton handle end to end is 14 inches remember this does not have thrust bearings and it's four threads per inch oh man it's tough oh it's getting harder oh nine and a quarter pretty good eight and a half I could definitely tell the weight of the handle took a lot more effort there we go nine but anyway all devices are pretty equal none of them have an advantage as far as opening it up faster for the next test I want to see how much each of these vices can clamp with the same amount of input now before when I did this test on some other vices I would just grab the handle and I would push down on it as hard as I can but a lot of you guys said that that was a very unscientific way of doing it and I would actually agree with you so what we're going to do this time is we're going to use a torque wrench I've come up with this little adapter that we can add to the handle and we can use a socket to add a specific input and in this case I'm going to choose something like 100 foot-pounds and we're going to see what 100 foot-pounds on the hardtail the Morgan and the Wilton puts out that's just a good indication of how little effort you may or may not need to apply okie dokie it's time for the Wilton we're going to set the clicker to 100 okay 100 foot-pounds input force here we go all right what'd we see 6410 and let's move to the Morgan Morgan eight hundred foot pounds in all right what do we see 3380. that's quite disappointing so let's put the probe in here and see what we got we go till it clicks what do we get 10 475. so we can apply less input and get more output because of the thrust bearings and the way this whole Vice design works and the Wilton kind of confirms it because it has a similar mechanism inside but it's lacking the thrust bearings the Morgan I can see why you need to handle this big you need lots of Leverage on to the next test in order to claim that this Vise is the best at to be the strongest and in a professional setting this thing is going to take a pounding whether I like it or not now that we've looked at each Vise design and seen what makes them special it's now time to put them to some real life tests much like hammering so instead of hammering like I did before I built this it swings a 75 pound Hammer from an elevation of six feet at a speed of well fast enough this thing is going to find all the weakness in this swivel base of this Vice Morgan and Wilton have had 75 years to perfect their vices we need to get this Vise underneath the hammer we're going to attach it to this plate and then this plate gets welded to the table so for the test we're going to be hitting this bar stock it's a big chunk of unmovable steel what we're going to see is this Force try to spread the Jaws we want to see this jaw try to hold on to this bar I'm going to place this right at the bottom of the jaw right at the end this Hammer is going to try to lever this whole Vice up off this base and I'm gonna just pull the handle make it as tight as I can get it by hand in order to continually hit this Vise and have the rig reset I've made a mechanism that lifts the hammer up to the top and gravity to swing the hammer yes I totally understand that no Vice is going to get hit with a 77 Pound Hammer in real life but this is a destructive test we want to see what fails first this rig is pretty neat because we can adjust it for every Vise that goes underneath of it and keep the testing consistent so I want to give my prediction on what I think is going to fail first the threads are gonna pull out of the nut in the swivel base literally just pull the thread straight out of it and then it falls over nothing catastrophic that's what I think is going to happen all right let's turn this thing on let the games begin first hammer test on the fireball hardtail in three two one go nice and slow and steady just make sure everything's working right okay coming up to the top get nervous here okay three two one here we go oh wow that was quite violent let's just check the rig out first it looks like the bar is held nice and tight but we're just gonna keep going the rig held together fine lifted up over the bar now it's time just to let it roll let's see it Go Again test goes on man that is so violent look at that though reset and up we go man if you have any questions about this machine or anything else in this video I've started the conversation at the fireball tool forum and I'll answer all your questions there that's pretty impressive oh my gosh oh man that is painful to watch the rig's doing his job though resetting every time I think we're up to hit 15. seems to be holding pretty good that bar hasn't budged you know you got a good Vice when you're worried about the hammer advice my advice is so strong it breaks hammers that's a t-shirt isn't it that's like a poster Hammer breaker I'm gonna put some ear protection on my body feels like there's something wrong like this should not be happening but I keep watching it nervous my glasses are fogging up 125 DB pretty loud I don't see anything happening to the Vise yet looks like it's holding strong gotta be up to 50 hits so far so I'm stopping the rig at 53 hits just to kind of do an assessment of what's going on here's what the pad looks like literally destroying it that's okay that's just a wear pad everything looks pretty nice and tight I don't see any paint chipping anywhere the handle's still in the same exact spot that I left it so let's go to a hundred and reassess the situation and see what we need to do to actually break this thing so I'm starting to see a little separation right here at the swivel base starting to see a little air gap [Music] I'm suspecting something's going on in those screws we might have to add more weight to get it to break but we're up to like hit 70. we'll just keep it going see how long it goes it's gonna take a while it's hard to experience it when that hammer hit like feel the compression in your chest you can feel the floor shake because the table jumps GoPros flying everywhere the rig really going around a lot faster now I see the vice doing a little jump when it hits but then it just settles back down to its natural position this next hit will be 90. this pace feels pretty good I feel like the machine isn't trying to break itself apart the last thing I want is somebody to get hurt so having too fast of a cycle time won't allow us to catch something going wrong that coupon has not moved everything's just happening with the base and that's exactly what this rig is designed to do is test the swivel base and it's performing just like it was engineered so the vice has made it to 100 strikes with this big hammer this machine is supposed to be destructing the vice and the vice is too strong so I'm going to add on this extra weight of 15 pounds this is like a 15 pound Hammer being added onto this let's see if this extra 15 pounds can accelerate something breaking and then if any of the other vices make it to 100 we will add this weight on Also let's see if this thing will fit so we're ready to do another 100 with the extra 13 pounds attached to it got to get this thing to break three two one go oh 88 Pound Hammer now seeing something loosen up but it's still hanging on the grip on that Vise is pretty amazing well what are you doing today I think the world's strongest Vice with an 88 Pound Hammer you know just a normal day it is getting close they grew up to like what 140. it's like when do we call it come on break stupid thing come on oh my gosh just break already so I'm stopping it at 170 hits and remember the last 70 is with this extra 13 pounds on the back let's take a look at the impact coupon here this thing's taking a beating this hasn't been changing the Jaws everything's holding tight it's tilting a little bit I noticed that there's getting me some slop in here and I think it's these just need to be tightened up some more stretching something in here back to tight again like nothing's ever happened to it okay let's keep going good thing I'm not swinging this Hammer anymore so I think this is a great opportunity to tell you a story about my experience with the vice so I was a Millwright in a steel mill for three years when the production line breaks down it cost the company a thousand dollars a minute so it's sixty thousand dollars an hour all the mechanics and all the bosses come out of the woodwork and they're looking over in your shoulder trying to push you to go as fast as you can to get the line running one late evening we had to fix some parts and we couldn't get the parts separated but we had to rush and we had to clamp the part in the Vise and we were literally wailing as hard as we could as mechanics to try to get these two parts separated could we have broken the Vise possibly but at a thousand dollars a minute the cost of a good Vice is priceless it's the only tool that can hold on to your parts remembering that experience on how that Vice saved the day when I built my Vise that I wanted it to be as strong as possible just in case those guys in the oil rigs the mill rights the blacksmiths the Fabricators the welders out there can rely on the Vise in case they have to abuse it that's why we're doing this test right now because it's really important to me that this Vise can stand up to some serious abuse oh the handle without a failure so let's take a look at what failed 283 hits the soil basis yes is getting loose I have not changed the tension on this clamp but oh man that thing is still tight this thing did not loosen up that's exactly where I set it oh man this thing is hot but what broke my Fastener snapped it was holding the jaw on isn't that nuts crazy let's see how does it turn still turns pretty good actually like nothing happened didn't expect that failure though this would be something easily fixable I noticed there was something kind of weird going on with the swivel base so let's take it apart and take a look at what happened there so my prediction was that these stretched good threads there this one doesn't feel that good threads started to strip and that started to bend kind of exactly what I predicted overall no catastrophic failure let's look at the center pin I broke it or that was already broke one of the two pretty amazing took all those hits to break the center out so what was happening that's been broken for a while but what was holding it on were the two side nuts gripping on the outside of that that was literally preventing it from coming off the center was on there when these stopped doing their job when they got loose this took the brunt of it and pulled the center out this is a replaceable part order a new one and you're back in business not a catastrophic failure and even then you don't even need the swivel base really okay let's check the screw out closes and opens just like a dream there's nothing wrong with this oh my gosh the Morgan still has more backlash this has still zero backlash to it that's good because we can continue testing with it here's what the Jaws look like there's really nothing wrong with them they're flattening out a skosh look how far the tables moved this foot used to sit right here this whole table weighs like 4 500 pounds and every hit it would just scoot over an inch at time that is mighty impressive Morgan and Wilton have had a 75-year head start on me let's see how perfect they have made their vices in that length of time only way to find out put it under the hammer so let's get the Morgan Vice bolted down the Morgan Vice only has three bolts instead of four on the base we're gonna put a brand new test coupon in here I'm gonna put it in the same spot it was on the Fireball and I think we're ready to go these handles are really tiny they hurt my hand trying to tighten them so I'm going to use a cheater bar I'm going to tighten this up as tight as I can without hurting myself here's my prediction this bolt is cast iron and it has that little tiny thin t-nut in there that thing's just going to Shear off I give it 10 hits It's just gonna snap if that doesn't break first I don't think that this Vise has the clamping power that the fireball has and after seeing what happened in the fireball I think that these bolts are just going to Shear off the Jaws I doubt it's even going to get to a hundred let's turn this thing on let's break some vices here three two one let's go [Music] it made one these are already loosened up after one hit all right it looks like we're ready to keep going there we go okay I'm gonna leave it on something looks awfully bouncy doesn't it but that table moved a lot saw something broke we've already sheared a vice jaw bolt off and it's starting to get kitty Wampus oh something's messing up here stuff's already breaking we lost the center bolt in the jaw let's just keep going three hits let's tighten the swivel base up all right let's keep going number four I'm gonna stay next to the off switch this won't last long something's twisting in the Vise here this is getting dangerous what was that six hits seven hits swivel base is completely loose I'm just gonna keep tightening it up just to keep it safe I'm bending the handles this thing is about ready to come out I gotta keep the handle tight I didn't have to touch this on the fireball okay let's just keep going oh we got a failure it just broke that's exactly what I predicted that cheesy piece of cast iron in there snapped the base off you know I'm a little disappointed let's just keep going see what happens see if we can make it another couple hits we'll tighten this one up 10th hit in three two one go oh busted 10 hits 10. that's it only 10 hits you know I really wanted to see this thing Go the Distance I mean this is three thousand dollars let's take a look at that on the high speed whoa the whole bottom broke out too ten hits what did I not predict that this one the threads snapped I've never seen a cast iron bolt before this makes no sense to me why not just make this a steel piece and then tap it with a real steel bolt there's the jaw screw it doesn't look like we lost any more of them I mean technically it's still operational which is a good thing just the swivel base took the brunt so after further assessment we did we lost two out of the three bolts those are pretty disappointing for a vice this size let's get the Morgan off the table and let's put the Wilton on here and see how well it can do Wilton has the worst swivel base out of every one of them boy this is a design I mean they don't even give you enough room for a bolt head I'm gonna do that with the wrench they don't even give you enough room in there to put the socket on that's just crummy these are all the things that nobody talks about can't even get a wrench around it come on let's put the bar in here so these handles are so tiny and they're so sharp on the end that I'm gonna cut myself basically forced to use my little cheater bar here now we're gonna tighten this up as tight as I can get it everything looks good and lined up you remember those little teeth that were in the swivel base that little piece of casting that little tab that holds it on they're gonna snap off this thing's just gonna go flying five to eight hits that's my prediction Wilton 600s destructive testing in three two one go oh gosh the first hit something's already broken oh oh it's already broke one hit I'm going to tighten the handles up a little bit okay it's it's snug back up again but this one's gonna go flying so hit two this is actually really disappointing I was hoping to get at least a 10. here it comes Hammer oh yep hit number two smasho oh my gosh well look at that see it broke right where I told you yes I understand nobody's going to be hitting their Vice with a 75 pound Hammer but over time this is a fatigue point if you do hammer on it the swivel base just won't last I don't think that this is bad manufacturing this is just poor design let's get this thing off here the first hit was already destroyed so after hit two the jaw bolt snapped off so it wouldn't be long before bolt number two snapped off a little disappointing there the good thing this is a replaceable part positives the vice seem to grip in the Jaws pretty well nothing really came out let's take a look at all the coupons together I think this tells a pretty good story of how much abuse it takes now what I often see in my line of work you need to remove a sleeve from a shaft and what happens is there's no way to really separate these sometimes except for a big giant hammer and a lot of heat I see mechanics myself included go to the Vise put it in the Jaws and then we will Hammer the shaft out using the Jaws as a set of parallels the problem with this is vices weren't designed this way so it puts a lot of stress on this jaw area right here and this is prone to cracking I've seen a lot of Jaws snap off this way so this is going to simulate the downward force that a jaw experiences so I'm going to make two immovable objects the race and the shaft by welding these together and then we'll put it in the Vise and then we will hammer down with a big giant hammer and theoretically try to separate them and see how many hits it takes for the vice to give up so let's convert the rig over to hammer in a different direction got everything lined up ready to hammer I'm just going to go one hit at a time and see what happens because the vice doesn't have a grip on this test bar here I'm just going to safety wire it feels pretty good the coupon can still float around but it can't come out so my prediction on where I think it's going to break I think it's going to fail with the Fastener right here on the back of the jaw that's the worst case scenario it's going to try to lever this jaw up and it's going to Shear the bolts off let's turn the machine on and pound away okay first hit three two one hammer falling oh gosh that was solid okay first hit I don't see anything that was a pretty solid hit and just to clarify I have put new bolts in the Jaws from the previous test to repair it so we're at stroke 50 and I see nothing coming apart on the Vise and I really don't want to be here for the next three days so let's add another 13 and see if we can get this thing to move tack it on Hammer some more brings us back up to 88 pounds okay let's keep going I'm pretty happy with the results so far if it broke right now I'd be happy I don't know if this thing's ever gonna break to be honest at least the other way kind of like felt something was loosening up we were seeing some progress uh things so destructive oh the metal keeps flexing let's just try some wood make it like a springboard just keep going [Music] 121 hits here's the top of the Impact Zone I'm just going to rotate it hand snug the Jaws so it just won't come flying out let's just keep going look how far the table's moved I can see it jumping over here it's it's moved that way it's hitting so hard it's cracking my concrete golly dang it foreign [Music] just hit 400 and I'm completely exhausted so I'm gonna call it quit let's see how well she did okay so our bolts are loose but nothing's broke that's pretty good sign still moves that's an even better sign I feel like it's loosening up a little bit but that's to be expected but overall she's in one piece I like it let's put the Morgan underneath this hammer and see how it performs so I got the Morgan Vice ready to go I have the screws replaced in the Jaws because remember they broke in the last test my prediction for this thing breaking I think the screws are gonna go popping out we're gonna see it split right there at that sharp corner and once it cracks we'll stop the test remember this is just Loosely fit in here there's just enough wiggle room just to keep it from not falling out not enough to add any extra clamping pressure three two one Morgan smasho did it break what you've got to be shooting me I'm kind of disappointed let's just send it one more time we'll give it the benefit of the doubt here we go getting ready to yank the extension cord out of the wall oh man kapowi what a cheese ball does anybody else disappointed or happy actually I'm kind of happy so we don't have to keep going man these screws are so weak those are brand new sheared sheared broken let's take a look at the other side broke loose this one's wobbly cracked right there I've seen this before in pictures online of people breaking their Vice this is actually pretty common the vice is not designed to hammer down the worst thing you can do for it it's still able to perform the next test so we'll put it back together and we'll throw the Wilton on here and see if it can do any better than the Morgan okay the Wilton's ready to go its Fasteners and the Jaws have been replaced because remember they broke in the last test also predictions I think this thing is going to break in the same exact spot there's quite a bit more material here to break off but it's still gonna do it I think I think it's gonna crack just like that three two one go good I like that all right that's doing pretty good it might just make it foreign doing some speed check on the swing of the hammer it's uh 25 28 30. so if anybody wants to do the calculations 75 pounds three foot arm and a speed between 25 30. that's quite a bit of force hitting that but we're at 50 and the Wilton looks like it's doing pretty good no cracks yet I'm pretty impressed let's do the same thing we did with the hardtail and add the 13 pounds to accelerate the breakage and see if we can get it to crack a little bit faster going live [Music] after we added this extra weight after the first couple hits I'm noticing this Dynamic jaw is getting really loose right here on this cylinder it was not like that before we might be losing this whole jaw here we're going to keep hitting and see what happens I don't want it to break because I want to do a clamping force test but I do want to see how far it goes [Music] so I'm at 313 smacks and I'm starting to notice a little tiny hairline crack come off that sharp corner probably can't even see it but it's there look at that next hit we're about ready to break it here oh bro oh now we're going down the body okay the Hammer's coming around for 360. oh stop it we just got a failure well guys just made 360. and I noticed we have a failure started that little crack and now the jaw came off [Music] I'd like to continue testing with this Vice so I'm going to stop it right here 360 whamos it actually did really good I'm pretty impressed with the little Vice Wiggles back and forth a lot of backlash look at the screw moving there's some serious casting wallowing out back there so that bolt is loose broke that one's still on how the heck did that work that Bolt's still good oh I bet you that's what happened when it hit down boom sheared this one off there's our piece anyway let's move on to the next test we're gonna see what its maximum clamping force is when we turn the screw I use a probe to see how high the clamping Force goes before ultimate failure so what I'm looking for is when max pressure is reached what point and part is going to fail first such as the handle the screw the nut hopefully in that order we don't know we have to see if Wilton has designed their Vice properly in order to do that the test is going to be performed at the maximum opening this Vice opens up to 10. we're going to shorten it a little bit just for a little bit of safety so it's at nine and this is going to stay standard for all devices why is it in this configuration well first off it's easy to see with the camera two it's much easier to put the cheater bar on it in this configuration and walk around it instead of trying to lift the cheater bar up and over the top I've done this before it doesn't work out so well this is going to be much nicer for everybody this Vise has 362 impacts on it so this is not a uh spring chicken by any means she's got some hurt and damage to it so that might play into consideration also if we were really doing this test and we really wanted to be scientific we'd start with a brand new one I also want to see what happens when a vice is abused can it still perform like it should here's my prediction of what I think is going to fail on the Wilton Bice I think the handle is going to bend first which it should that's the first thing that should fail I also think the dynamic jaw is going to completely Bend rendering this Vice useless all right let's see what we can squeeze on it first okay that's six thousand let's put the cheater bar on it I'm gonna go forward that way if it breaks I can catch myself I've seen guys at the shop do this kind of thing and I cringe every time they do it eighteen thousand holy moly with the bar this big we should be higher than that need a bigger cheater bar okay the bar is starting to bend at the bent bar at 22 000 pounds so that's a good sign theoretically we should be able to loosen this up and everything should be okay all right so the handle bent let's see if it still goes down looks like it does yay Wilton engineered the handle appropriately what I want to see is this next part that fails if we keep going so I'm going to weld this piece of pipe on top here that way we can put our cheater bar through it and just keep going look at my new cheater bar holy moly I'm gonna have to clear the shop out 25 000. sheesh this is pretty hard to get to 25 000. something's letting loose it's getting easier maybe it's my imagination nope I see the force gauge really isn't doing anything anymore something's about ready to break 30 000 pounds this is all fight to get to 30 000 I saw guys do this with a little 14 inch bar the trade shoe bending my bar [Music] whoa dude just broke it Thirty One Thousand eight hundred snapped that jaw off okay I'm not going anymore let's see if we can back it up it's dangerous snapped at 31 000. sheesh Wilmer did better than that at fabtec didn't he that there is a catastrophic failure let's see if it'll go back oh oh no somebody broke the Wilton so let's take a look at the Wilton design and see what failed first obviously the jaw snapped off and that's right where the probe was don't clamp on the edge that's the worst thing you can do for a vise this round tube design you know it's really not that strong is completely seized up I mean it's barely moving so this is bent as we could probably see from the image and obviously the Jaws are not in alignment anymore they're offset let's pull this Wilton Vise off let's put the Morgan Vise on and see if that's a better design than the Wilton so here's my prediction on what's going to fail first on the Morgan first thing I think it's going to fail is the handle second thing I think the nut is gonna get bound up on the spindle which is going to cause it to bind and then we're gonna Shear it off I've got the Morgan mounted up let's get the probe in and let's see if the Morgan design is any good we should see this handle fail first I'm gonna see how much I can crank it by hand 8345 with a few good jerks there boy it's getting tough 23 000 the bar hasn't bent yet so let's switch to the big bar oh yeah much easier and I'm further away from the vice when it breaks I like that 30 000. I'm gonna stay clear for this thing okay so the handles failed and it's bent at 30 000 pounds so handle fails before the vice does that's a good sign so I'm gonna do is reverse it take some of the pressure off of it and then we'll weld that pipe on the top almost back up to thirty thousand pounds here pressure's going down something's gonna happen here don't know what when the vice doesn't want to go up anymore that means something stretching threads are getting stripped out castings failing wow we almost made a full Revolution only gained a thousand pounds something's breaking oh dang oh dang holy mackerel oh my poor probe what'd we get up to Peak 32 479 inspection time oh oh we broke the spindle off snapped it off broke it right off in the nut seized up good luck getting that out of there so that is a good design failure I'll have to hand that to Morgan that is exactly the way we'd want this to go I like it 32 400 handle spindle these things are repairable something to remember this Vise is practically still brand new it only has what 11 12 impacts on it from the hammer but I'm also noticing the weld is just gouging into the slide the weld is harder than the cast iron this is just going to get grooves in it over time you can already start to see it I don't think that's a good fix or repair so let's talk a design on the fireball first thing that I've engineered to fail is this handle you see these grooves in here this Vise goes so high so fast that I've had to reduce the diameter this handle is designed to fail at around 35 to 40 000 pounds so this Vise is designed to be literally operated at like sixty thousand pounds what should happen first is the handle should fail then the next thing should be this nut inside this hardtail casting should fail after that in theory like I said before all I've done is CAD simulations this is the first time we're really testing it to ultimate ultimate failure another cool design about the handle is if it does fail you can just unthread it and you can buy a new one realistically if this handle fails you've overreached my design parameters so let's put it in and let's twist this thing off and what these grooves are also designed to do see how they're close up here it should bend at these grooves first I also want to note that I should be using a brand new Vise for this test this one has 800 impacts on it this Vise has to be compromised in some way I'm going to just see how far I can squeeze it by hand there's 18 000 with the handle and I know I can do more if I refund it harder let's go with the little bar oh this is like super easy 26 27 28 29 30 40 or at forty thousand the handle is bending forty thousand pounds can I loosen it by hand foreign oh that's the beauty of those bearings in there that's incredible let's weld that on let's start this going around 28 000. 47 000 54 000. we're just gonna keep going and see what happens I'm willing to sacrifice the probe just for some sort of number so we're gonna be out closing to double the other vices here 58 000. come on ah heard some crackling I don't know what that was all about okay almost to uh 60. is that what I was hearing crackling is the bar so it's probably gonna Bend again I gotta get a stronger cheater bar shoot sixty thousand pounds what to do what to do we know we've already exceeded my Design This should really have break in the tube nut let's see how much more force it takes let's release the pressure and let's put a 50 ton hydraulic cylinder under here and let's break something shall we so we broke the bearings okay we're free okay the vice is doing good I'm gonna see how it still operates this is just the spring on the back side here compressing it's doing what it's supposed to it's not supposed to be like this in this orientation so the screw still works it's not Not Bent let's see how the Jaws line up besides that thrust bearing getting wasted what what the vice closes perfect I mean not a Bend at all look at that dude those jaws are perfectly parallel still this is going to be bad for business because then when you guys buy this thing you're never going to need another one what am I doing to myself this hydraulic jack is an air over hydraulic so I can stand far far away as we pump this thing up so I've tested quite a few bench vices 60 000 is the highest I've ever seen any Vice go there are people out there that are going to abuse it this advice is for you look at that let's put it off to the side right where we are hitting it I want to try to twist this head off I want this sucker to break okay probe gonna go into probe Heaven here I'm really excited because this is my first time actually breaking the hardtail vice to complete failure and I'm happy you guys are here with me to experience this excitement I hope that this tail pulls through the bottom that's what I'm really looking for but realistically anything can happen this is the same Vise that we hit with the hammer over and over and over again some things probably compromised in here and we're gonna find it let's go hide somewhere okay here we go three two one air thirty thousand sixty thousand seventy thousand eighty oh yeah I mean you're jumping sort of cracking eighty two thousand ninety thousand this is nuts this is way too strong the two things are happening it's not going up anymore can't break it so we got it to break let's go see what happened ninety thousand pounds oh my gosh [Music] thank you [Music] what actually broke oh yep it broke where I wanted it to that's exactly exactly where I wanted this thing to break dude seriously this is not even a catastrophic failure just pull this out this is a replaceable part insane the screw straight as an arrow looks like let's look at the slide it's too dang straight still but dang man that is impressive seriously wow another thing I wanted to look at from all the abuse from all the impacts from literally testing it to 90 000 pounds how are the threads threading on pretty nice and the threads are great now we're starting to get a little tight okay so maybe we stretch the threads a little bit right there but not bad not bad at all I'm really happy with that this Vice exceeds my expectations actually let's take a look at the other half absolutely that's exactly where I knew it was going to fail that's my next engineered breaking point right there this component's still good this is the next chain that I wanted to break the handle then this nut man it worked out perfect except for maybe this is a little bit too strong abuse this took in the hammering test also when we're trying to break the swivel base off this nut was taking a lot of abuse I am beyond words it's way stronger than I ever thought it would be I am extremely impressed so now that we've seen this Vice in action I truly believe it belongs in your workshop and now you can finally own it because I have them in stock at the fireball tool website and you can find them there foreign
