BOLTR: Skillsaw 77 | Made in USA vs. CHINA

gentlemen come back this job today a treat especial I kind of got cornholed by my old procrastination what you thought I was gonna weld well so did I but some old codger came out with a Skilsaw to jail what piqued my interest enrico should probably move this and likely we're gonna get some gravity in there that's when the men were men and cheap were scared Jesus so what we're gonna do is get two birds stone one bush we're gonna send this off after we do the compromise ation betwixt in between the new and the old we're gonna send this to the tool restoration channel and he can have a go at it or throw it out or whatever the [ __ ] he wants I own some other parts as well yeah that's a great channel but what brought this on is the craftsman Channel I forget the name anyway you know a silver-haired foxy fellow there been working in the trades for here's the thing when you when you work in heavy industry for any amount of time right off the hop you can tell the [ __ ] goofs from the quality and this guy that is absolute goal to be able to look over the shoulder of a master and pick up you know stuff that was hard fought for him 30 years ago and you just you pick it up for them for the cost of a subscription which is [ __ ] all it's free it's just it blows my mind so I actually really enjoy this channel kinda longer form a bit of a rambling chat and you know and the thing is about that also class act right you can watch him and your mother's Hacienda on her on her Chesterfield her vinyl covered Chesterfield no problem wouldn't say [ __ ] if we had a mouthful of it the warm Norman Rockwell glow of false nostalgia side while this was completely metal as witnessed by how heavy the geez list thing is pity the poor car painter what's got to climb up on the rafters to wake everybody up at 6:30 a.m. on a cold fall morning look at that aluminium magnesium that's aluminium that would just sink the heat right out of your hand you'd be whoo oh ho my knuckles are aching just thinking about it so there's something to be said for newfangled plastics at least they don't heat the sink yeah or sink the heat nearly as bad as metal now once you got working her though of course the heat from the motor would sink into the handle and actually keep you warmer so to be one of those things you just just have to have an extra-long dart and cinch up your belt an extra notch or your suspenders and give her until the saw actually warmed up much fun to be had also on account of this metal bodies what for sending a tingle through your Dingle you send the apprentice up to cut some rafters not to worry just just hung onto that TV antenna you won't fall yeah now even you're working this in the rain this is like you up like a Christmas tree because any the brushes of course are open any kind of moisture what gets in there is going to turn this whole thing into a hundred and twenty volts so what we do is we add a ground lug so that allows the voltage to go from here to the ground instead of going from here into your body and into the ground so they've added a little wire here this must predate that ground lug and I guess you would stick that on a metal and close your box you know where you plug it in or something like that to prevent this from being at 120 volts AC when you go to grab it yeah get a nasty surprise that's for sure well it's built like a triple coil or [ __ ] brick it's still not indestructible got a little snag here and this must have fallen and broken the casement also would not surprise me at all if this is completely seized up on account of well a clue a clue so something has been leaking for to make that fudge let's see if there oh no okay we're still good we're stuck I cleaned over this this is the model 77 I don't believe it's the mag 77 I think this predates the magnesium this it would be aluminium I'm assuming but it would still be very well they're both very light magnesium is a little bit lighter but still they would be very rigid this would be cast of course with a whole lot of silicon in the material so that when the when it's solidified in the mould you would have small small grains so that silicon allows the crystals of aluminium to to form very quickly to crystallize quickly and and has they don't grow too big so you reduce the ductility you increase the strength you reduce the ductility that means it's not as bendy it's not as bendable so we see here they haven't gone with a magnesium or aluminium foot it's it's pressed steel why is that because very high ductility is high strength as well but it's very ductile that means you can bend it so if you drop this and you bend your foot you can bend it back and it's not gonna break now part and parcel of having a very fine rigid grain structure is it's very strong but it's not very ductile so the essential craftsman at what the fellows name is the essential craftsmen how to question it his mind that he was going to check out just by testing whether or not these magnesium bases well first off these are diecast so this would be injection injected into a die a tool steel die probably age 13 and then solidified solidified deferentially so cooled in different sections if you were to cut this I'd be willing to bet there be some spring in there because there's internal stresses they do that on purpose when they cool the injection not the injection mold but the die casting when they cool these they cool them differentially so that there is some spring in there that they're more rigid than they would be if they cooled at the same rate so if we cut this it would very likely spring a lot but you get that if you ever if you ever are able to cut an alloy wheel off a vehicle you'll be [ __ ] amazed the thing will literally go from straight you get the saw in there and then it just goes poing and that is because there's so much built-up stress from the differential cooling they do that by purpose now long story short this is going to be not very ductile at all just by looking at the manufacturing the die casting and the material it's not going to this thing is going to break not bent essentially is what I'm telling you it's gonna break it's not gonna Bend and once it's bent you try and bend it back it's gonna break at the end of the vjo I'm gonna give this away to a commenter on the original teardown I'm gonna send them a basket case though we're not gonna put this back together we can let him put that back together so I don't want to ruin the foot but what we can do here we'll stick the dick and device and I'll just show you what I mean engage your safety squints there's gonna be some splintering you see what happened there okay we didn't Bend we actually broke a chip off so it's very very rigid it's very tough to bend but when it does Bend it breaks now closer look at that focus you fought thank you you can see here you don't get that with steel it started to give here come on started to give here and then it took a chip out like a brittle material like a teacup same thing here where the jaw was engaged it took chips out you don't get that with steel it bends it its moves overtype deal it mushrooms it doesn't chip off that we can see very rigid but you bend it you [ __ ] gotta buy another one because you try and bend it back it's gonna break no blade lock to be found but the blade does have carbide inserts so it doesn't you know it doesn't predate now let's see righty tighty except carpenters lefty loosey lefty loosey we'll get her okay we'll get her there we go there we go that's the one yeah lefty loosey you tell how much I use a circus aw as little as humanly possible Oh interesting blade look at off Wow and the seals blown right out of her clearly mm-hmm turns out it's just rusty is Frigg and the blade as witnessed by the summer teeth used for I would say by forming carpenters I know that because I stripped forms I was a stripper put me through school a [ __ ] hard work speaking of young dumb and full come my buddy got me the job and it was good pain it was like 14 buck an hour just for unskilled labor but the thing is they paid more but you had to give her now no [ __ ] [ __ ] around no no backtalk just a year [ __ ] you make the cut you're in you don't you're down the road so I wanted you know that was a good paying job in between classes so anyway I hadn't been hardened I wasn't hardened up yet and I saw the boss come around a you got those you got all that was normal that you got those two buffers all declawed and so forth yeah yeah there's two skids there some more just about finished okay well finish up there and get started on those two skids I want you to cut steaks I want you to cut steaks oh yay long real sharp pointy and then once you once you're through that big old pile come and see me I got more for you so I set to making steaks and [ __ ] day here's what you do right you cut it to length and then you bend down you sort of rested in the crook of the inside of one foot across another foot the other foot so it's kind of kind of leader it off and you're bended down you got the circ saw and you gave everyone cut like this and you flip it over get a real one cut like that so what I had been doing was cutting both sides but then the blade gets close to you you know I kind of sketchy so here's me thinking right you flip it over so about day to get in get in the crummy go home [ __ ] me boys ha I don't know if I can this is tough my back is just wrapped just [ __ ] wrapped so I'll kind of give a snigger and well you got any tricks for me yeah you're the [ __ ] fancy-pants going to school you're surrounded by lumber you're surrounded by tools why don't you knock together some fun oh [ __ ] knock together a [ __ ] workbench you idiot smarter not harder I don't know if this bit of Bonny work is by design or by the fact that it's worn right in no guillotine action on the guard that's beautiful as the evidence points out this thing it thrives on abuse and neglect but we see a material property this is aluminium and we can see it's fatigued it's it's been bent and instead of bending it's actually cracked so we can get right in there we see let's see yeah look at that you can focus you [ __ ] there you go there's a crack right there cracked right half and two well yeah that thing is not long for this world we'll have to be rather ginger carefully with a Oh helps if you or the right direction so [ __ ] tough now are ya tappy tap tap Oh hahaha would L [ __ ] hippie hair hahaha it's on my hammer now blue nothing [ __ ] grosses me out worse than even worse than dead tree carcass both people shmoo yuck look at this old tech felt seal stuffing box and see how effective it is not very well the it does the auto oil change so you never have to change the oil you just keep adding oil there is no ridges here from abouna and double lip seal no ridges at also complete nowhere at all of course with the with the nitrile rubber any kind of ingress of dust or anything it embeds in there and then where's that seal out and we see the effect of however many decades of use with a felt seal doesn't work the best but it also doesn't wear your components there's a trade-off there it's a beauty part here this would have been remember this would have been machined by a man not possibly a woman or maybe even none of the above okay yeah can Dean to assume someone's gender nowadays but somebody came in here this would have been a solid chunk of round stock bucked it off and very likely he would have broached this so they would have drilled this out then broached it in a press cut cut this OD cut this down had a little champ for your on here cut this down to size to fit perfectly in the bore cut this face here face this off and came in with some sort of grinding tool or milling tool and we can see it was quite big because of that radius there would have been a big one came in switched came in machined it switched came in machined it and then ground and lapped this face look at this face here look at that that's been ground there is a lot of soul in this little part this is very labor very labor intensive manufacturing big bronze oil light bushing and then a spring them a thing what's been anchored and index point way deep in there and see not too many value engineering sessions got put into this basically this is what you're this is what you can do when you're the only game in town this make it so friggin Skookum and not even worry about how they put it together don't worry the boys on the floor will figure that out what we need is a spring right there you never yeah look at that how the [ __ ] do you assemble that in a hurry all that construction talk jostled my memory this is funny as [ __ ] and her MA Shawn this is how corporate YouTube video should be all of them I've been doing this about four months and I'm certainly learning a lot that's what people tell you when you work construction they say stuff like wow it's real work you're gonna learn a lot doing that and it's funny cuz none of those people actually work construction and I think it's for those reasons it's real work and you're gonna learn a lot soon and I've certainly learning a lot I'm learning a lot about being an adult you know stuff like powering through emotions being hungry all the time and a shart I've never had a shart before but I know I'm pretty well now if you don't know what a shart is the ingredients are overexertion and gas-station cookies you can make one at home if you want just pound three of those and try to lift a stack of two by fours you'll figure it out but first I didn't think I'd fit in because some of these guys they use phrases like a C hair and I came in using phrases like a wee bit and a smidge gonna be direct when you talk to people on the job but you don't have to be good with like words because that first you say about three things you say yeah and then that laughs people do and they almost die like sometimes a paste and press for a framing make for a tense work environment right you might be given very bad instructions and be yelled at for following them or be given very specific instructions and then be yelled at for following those what's under here Oh a nice cork gasket look at that cork like they grew from a tree and the problem of course with cork is it's impermeable it does leak it loses shmoo and yeah that's a little bit gnarly but nothing compared to an actual human hair speaking of value engineering here's the way they properly did it they retained the bearing not with three little four it's like in the new one where is that part yeah yeah look at so what they did was they took a first nerd just with washers and it's actually proud of the housing so they got the washer all cantilever it's real goofy arrangement this is a was a sixty two oh three RS so double lip seal sixty two or three that's the but that's a benchmark bearing for me it's the twelve is chasing after the seventeen to tell the forty that it dropped a thousand-dollar bill so this'll take a thousand pounds static oh [ __ ] I lost it is a static or dime no static and it's 12 millimeters thick 17 on the ID and 40 on the OD very standard bearing you see that in a lot of stuff they'll be interesting to see what this bearing is we can see the retention much much better they've got a pressed and formed well a die over a mandrel they formed this punch pressed steel retainer oh just give me the shivers but so we'll get that a part and see what kind of bearing is in there I got a feeling it was bigger back in the day a little mild steel punch here very short well that's bronze Oh hmm now what do we do maybe aluminium maybe I'll go find an aluminium stick sometimes you get lucky even a Blind Pig am i right just fell right out of there there's meant to be this little barren cow made in the u.s.a n.d 3200 series made in the USA that ha ha that's a museum piece right there now you want to talk about a beautiful part this would have been done on a hobby machine and ground look at the surface finish triple start touched by human hands broached turn the OD ground this our work cut then cut the [ __ ] and then ground it that's a that's a beautiful part right there oh [ __ ] yeah you know it's a good when there's [ __ ] Schmo everywhere stickier the better this is interesting because I'm going to show you here value engineering at its finest you never know changes ever get made just for the sake of making changes the reason someone makes a change to a tool or design is money either they want to make the component cheaper or the component failed prematurely and they're losing money because it's not it's not reliable enough and the customers are getting wind that it's not reliable enough so the marketing department says hey listen we got to increase the Chooch factor on those because we're not selling them anymore they're too cheap you see this all the time now look at the drill I just took apart from the hazard fraud the hercules one it advertises on all-metal gearbox now if you go back in the vid i took the gearbox apart it's plastic housing so when they introduced the tool it very likely had all-metal gearbox but the value engineering team came in and said okay right these are selling okay let's reduce the price how do we reduce the price more plastique everybody wins so in this case we go from the ancient design to the new design and we see just how much they pair off in each iteration I don't know how many iterations this has gone through betwixt and between these two but we can see there is a market difference in where the rubber hits the road have a look at this so here's the olden expensive part beefy whoa look at the bearing on the back here's the new one same thing ostensibly looks the same there's the bearing on the back okay a little bit different there on the front side this one's got a spline very robust design expensive to manufacture it has been ground on the OD these splines need to fit perfectly when things need to fit birth they're more expensive to build here we have just a turned OD in a bearing and the drive is a square drive no more splines it's just come in with the CNC right right right Don son well look at that everything because there's more gear teeth that means the gear teeth can be smaller that means that this worm can be smaller here we have a four start worm looks to be quite a bit more fine that would mean that this would need to spin a bit faster in order to get the same speed out of ER now these old motors don't spin them a thing nearly as fast as the new motors in a lot of cases here's the old one though it is a three start lots and a lot of meat there lots of meat on this guy you see the difference I think probably fifteen gear teeth on this one twenty nineteen gear teeth on this one quite a bit different quite a bit different so this to manufacture this part well here's the other thing wait a second here one thing they've done is you always want to reduce the bill of materials count reduce the amount of devices on the bill of materials lower the count the lower the cost well we actually have added a nut why would that be cheaper than just a fixing this permanently to the shaft well now your tolerances don't need to be as tight to get this to stick on so this guy you would need to heat up and you would need to press fit fitments and pressing and all this expensive production so what they've gone and done is just gone okay well what we'll do is we'll we'll have a keyed shaft or something and then or not even a key chop we'll just put it on there and then by fact of how tight they torque this down there's no key very likely there's no key in there it's this not what's keeping everything together or I should say the nut or the force that the nut is clamping down that keeps every together from a spin of a thing so there you have it 50 years in the difference in what you can see a lot of engineers have been in there tinkering and teasing around if you look at the outside though it's the same Drive but I feel if you have a look on the inside completely different I just notice this further to the value engineering this looks like a really a traditionally machined this would be a very expensive part but this is actually a metal injection molded part so powdered metal centered together they can get all kinds of complex geometries look at this though they went a little too far a little too far you see and what I'm seeing it's [ __ ] cracked right half and two at the root of the key right on that square shoulder hasn't even been used it's [ __ ] busted right half clean and two now that is well I didn't know [ __ ] good at all I done said before you do not want to be swinging this dead cat around by the tail all day it is heavy and we see why it's so heavy a lot of the weight is just in steel steel laminations for the field this thing I don't know how old it is 50 years old nothing weeble wobble and around on account of being properly wrapped and dipped no expense in manpower spared to get this thing to last a goodly long time we compare that now to the new one with the conductor's just flapping in the breeze all kinds of nylon plastic parts but it is crappy I got her by the skyhook there but I mean [ __ ] which one you want to carry around I just wish on the new one they did a better job with the field like look at these these wires are just dingle dangling and the [ __ ] zap zip ties come on come on now here's the commutator here the rotor look at the size difference look at the size difference now this is both pressed steel fans that's great that way you know you don't break a chip off you don't break all the blades off that just get Bente but in this case at least they have some been to them this is just a flat blade impeller which would work of course if this was a reversible tool it's not a reversible tool so better fan on the new one look at the size difference you can see so if you're getting the same amount of power out of less copper which one is going to last longer well this one's going to last longer obviously because there's less heat density a cute little feature how they used to balance these they just put a chunk of copper and tack it in or not tack it just um a center punch it in no that's a cold chisel like hole chisel it in place that's how they did that and blue die come die or blue die on there and that would tell you that would tell you if it was ever rubbing on the inside of here if you if you see this with worn out you know it's rubbing on the inside this a beautiful artifact of a bygone age but would I want to use this every day walk no give me a little bit of plastique and a lot less weight just don't chintz out too much like that come on this is bad this is bad another long dirt in the coffin of this value engineering now no question this this old one while it's not an everyday carry far more robust than the new one I'm gonna last a lot lot longer this value engineering is great for making it lighter cheaper but you can go too far case in point nice big bronze oil light bushing for the guard for the guard look at it I mean look at it like the amount of material in there here is the bushing nowadays a chintzy plastic duller and pee like a [ __ ] garbage look at that this is gonna be weeble wobble and in absolutely no time at all old versus new now very rarely are there improvements there always changes so that it's cheaper or they have a talking point for the market there's no changes happen for no reason right or changes hat don't happen for no reason okay moral dilemma now knowing that this is broke right - - how do I give this to somebody I think I give it away as a basket case they got to put it together themselves that way we well here what's the gray I've been trying to do do good in the world especially I got a daughter you know I got a but yeah I have to think about things as a as a upstanding or at least semi standing man now what's the greater good here cuz somebody is gonna put this back together and very likely bring it back to the store and say I didn't want it or it was defective they'll put this back on the shelf some slob will get it what doesn't know this is cracked right happened to so what is the greater good should I bite the bullet and scrap this I'm asking you now should I bite the bullet to scrap this and call her good I paid my money we had it apart we saw how it reached or should I pass this on to someone else at the risk that it goes on the shelf back on the shelf and some unsuspecting consumer gets it with this broken nut that's a tough one I got to think about that thanks for watching keep your dick in a vise I think I know what to do first to thine own self be true so I'm not comfortable having a busted tool out with my name on it out in the world so what am I gonna do I'll offer it to buddy canoe there because he's gonna need some spare parts for his new one like the foot that he breaks right half into and then it's a win-win he's not gonna rebuild it to use he can keep the spare parts on the shelf something breaks he's got the spares yeah ya know whether or not he accepts my offer that's another thing all together
