DoAll Mill Gearbox Service / Surface Grinding V Blocks & New Gerstner Tool Chest

so so precision takes time therefore precision is expensive and that's why these v blocks are extremely cheap because they're not very precise it's probably the cheapest set of v-blocks that money can buy overseas fly cut rougher than a cob v-blocks now i don't have a set this size that are any that are accurate and what i'd like to do is at least get started turning this into a relatively precise set now surprisingly these are within a couple thousandths of each other and for what you pay for them that's pretty good and you don't buy these with the intention of using them on your more jig board you buy them with the intention of using them on the drill press potentially the milling machine so you know you get what you pay for so i have the tooling to turn these into something more accurate i would like to increase their accuracy by 20 times at least get them within a couple tenths of each other so let's at least get started on this because i don't have a set of v blocks that are any good that are this size and it's something that i want to do so the first thing that i'm going to do with these is grind one side of them and establish a reference and then i'm going to use that surface that i grind well i'm going to flip them and grind the other side after i do the reference surface then i'll use that reference surface to mount to my other reference surface to do all the other sides and i'll show you that as well i got to set up all my stops i'm going to mark these so i don't forget which side's the reference although not sure it'll actually matter [Music] [Music] [Applause] [Applause] [Applause] so [Music] oh so man that made a heck of a mess that shot all over me in my face and my beard on my tool box probably three gallons out on the floor and the reason why this line came off is because for one it's not set up properly when i turn off the the coolant up here at the grinder head it dead heads the pump the output of that pump has nowhere to go all that pressure builds in the line that's a pretty stout little pump and plus what i was using was a compression fitting a teflon ferrule which is pretty slippery in itself on plastic tubing so once that pressure built in the line when i shut off that valve it just pushed this tubing right out of the fitting and then we had a fountain of coolant so what i'm going to do to let me get a little get you a little closer and show you these ferrules so what i'm going to do because i don't have the fittings that i need here [Music] to do it the right way i'm just going to put a bypass in here that way a bit of the coolant always get returned right back to the uh to the tank and i'm going to use a brass ferrule instead of a teflon ferrule ideally i should have an insert in this soft tubing to hold it but i don't so this should work if it doesn't we'll just spray the cooling out on the floor again cute little so now that i've got this face and this face nice and parallel with each other nice and flat i took the block mounted it to my granite square that has the inserts in it they're steel inserts i'm indicating it in making sure that you know it's really really close and that this surface here is proud of the top that way i can set this block on the grinder because it has steel inserts in it on the side that's on the plate right now and on this side i can grind this i can flip this 90 degrees on the surface grinder and then ground this surface here then i can take this off of the granite block and then use those surfaces that i ground as reference on the mag chuck and ground in the other two so that's how i plan to get all these surfaces parallel and square with each other so there it is set up on the grinder now some people may say you probably shouldn't use your granite on the grinder as long as it's cleaned really well i don't slide it around on any goop or grit it's not going to hurt a thing all my holes are blocked up i can't think of any other reason why this would have metal plugs in it other than to hold down to a magnetic chuck and plus i don't do inspection work anyway so it'll be fine so this granite square was a gift from my buddy andrew who came down and helped me when i was shooting the roof a lot of you guys who watched those videos will remember him he brought me this along with some other stuff that he had picked up in an auction score and this thing was so dirty when i got it this uh granite block that i put it in a bucket of water to let it soak it was so greasy and dirty it probably took me an hour of scrubbing it with a brush and dishwashing liquid till it came clean so it's not in calibration it's not some super precise piece but it's perfect for this kind of work and having those metal plugs embedded in it is awesome because it like you see can be used on the mag chuck it had to be custom ordered that way nice piece to have hmm i'm freaking out yeah yeah i would go tell mommy to keep you safe he'll be full grown in the next month next few weeks so here's the setup that i'm going to use to grind the v's and the blocks now this is a sign vise a grinding vise that is adjustable it's got two rolls four inches apart this is a stack of precision gauge gauge blocks got them with to the tenth which is plenty good enough i mean what are you gonna ask yourself how accurate does it need to be for your uses and i'm not grinding optical glass so this should be more than accurate enough you could really set this up with a set of precision angles right you can buy those really cheap but all this stuff can be had pretty cheap these days especially the gauge blocks where at one time you know only big companies could afford a nice set of gauge blocks now i mean they're in the within the reach of most people a cheap overseas set of gauge blocks will do the majority of stuff that most of us are going to do um this sound vice new to the shop this was a gift from joel and tessa the folks that come down from colorado that also brought the angle cast angle that i showed last week he brought me this he brought me this he brought me that nice hand forged bottle opener and along with some drills and some tool steel drops so i appreciate that i'll get quite a bit of use out of this thing so there we go should be plenty good enough for my needs so i'm gonna stick these in the vise take them over to the grinder dress them flip them and this should be done so unfortunately to grind this i'm going to have to change the wheel the wheel that's on it's just not big enough and i don't have any extra wheel hubs i hate to take this off the hub because it grinds so well but that's the way it goes right you get a wheel good and balanced you want to leave it alone unless you only have one hub i haven't yet made a wrench for this or at least if i did i don't remember making it and i sure don't know where it's at this is left-handed at least it went crazy tight so uh so [Music] [Applause] [Music] huh thank you love appreciate that i'm gonna drink my coffee first said i'm gonna drink my coffee first it's more important [Applause] so there are a few things better in my opinion than a really nice day outside that you don't have to actually do anything right your time is yours with a cup of coffee in the shop it's nice doing setups that you enjoy now this i've never ground a set of eblox before in my life so this is the first set ever i'm not saying this is how you do it it's just a way to do it that i'm sure will work never got a great finish with that wheel that's on there i have used it before it'll work fine for the for the needs that i have for these blocks i'm sure it's probably a combination of the grinder and the person running it as to why but grinding is a deep subject for sure there's a lot to it it's not just as simple as making some sparks and turning some handles that if you want really good stuff it's it takes some skill it's really nice to be able to use my equipment now as that's it feels so good to be able to just you know work in here with my machines and not have some big glaring hole that needs repaired there's still a lot to do i got to run wires to these machines to this one the drill press because right now they're just draped across the floor i have to run those in the attic i'm going to pour this front pad this section of front pad probably at the this fall maybe sometime around then that's what i'm hoping anyway finish this concrete out and then probably for an apron hoping you know finances allow if finances allow um an apron out in front of the shop that would be so nice a con tapered concrete apron with an awning over it so you could pull a car up on there and work on it if you wanted to and then potentially a little shed of some sort out back not something elaborate just somewhere to keep all my non-shop related tools like yard equipment and shovels and so on so it doesn't clutter up my workspace got cabinets left to hang and you name it siding left to do shops nowhere near done but it is good enough to use and now i can do a little bit of everything it's nice nice to be there took a long time [Applause] uh [Applause] [Music] [Applause] [Music] um [Applause] so once i'm fed all the way up to the back of the block it's really close to the edge of the grinding wheel and you could easily crash a setup like this so i've got a zero set on my dial that i just watched for each pass but it wouldn't take much to run this whole set up into the edge of that ground wheel causing yourself some some big problems so now that i've got this side of the blocks matched i can take these blocks i can flip them i can grind down to the same point then i'll dress the wheel and flip them a couple more times grinding down to the same point on each side that way the v is centered in the block and then they both match so that old worn grinder is still more accurate than a milling machine so these are nice probably within a couple tenths of each other that's what i'm guessing nice matched set that are square and parallel on every face so finish is not that great but i never get a perfect finish on that grinder so there we go they just need a good deburring get some real meat hooks on them so if you buy a set of e-blocks like that and you got a surface grinder you can turn them into a decent user set um you can consider those v-blocks that you buy a kit there you go turned into a nice set so as you can see i'm still not finished with my siding i just decided i'd stop on it until the weather got better and warmed up enough to where the ground would actually dry some because right now all this is ladder work and it's not i don't want to be on the ladder on this hillside in the mud just not not very safe but i did put some stakes in the ground drove them in i tie wire to it and then hook the feet the bottom feet of my ladder to that wire that way i can angle the ladder more i'll finish that up one of these days so check that out third and final cabinet hung above the workbench turned out really nice i think it looks really good i was concerned that it was going to shade the workbench from the light which it does but i put a light under here so not a problem i was also concerned that they would block me from putting anything tall on the workbench these are 16 inches deep so they stand off quite a bit from the wall but i was like well you know i can always scoot the workbench out in that off occasion that i get something that needs to go on this bench that's taller than the clearance that i have available so turned out really good i'm happy with the way that it looks i'm glad that i've got all that storage space now and pretty much this area other than arranging my tooling and stuff is done so i'm over here at the welding bench making sure that this torch of mine is set up proper for a cutting job that i have out here in the driveway just a quick job of cutting some 3 8 inch thick plate steel or 10 up to 10 millimeters and there's a variety of tips that you can get with these torches depending on the thickness and material that you're cutting and this says 4 3 8 material that i should be using at sc 12-0 which is this one it's a really nice torch now i've never cut steel with it i have done some brazing jobs up until this point i've only had experience with the victor torches which are a little cheaper than this do the same thing this is just more industrial version so make sure that i'm set up proper with both the tip and my regulator pressure i'll show you that on these uh these are victor regulators and they're almost foolproof almost let me show you them and we'll go out here and cut some steel so these are the regulators that i'm using on my tank setup these are the edge series they're made by victor and they're really nice because they give you on the scale they can tell you both when your tanks are full or getting close to empty and they also tell you where you should be set or at least give you a range of where you should be set for cutting heating welding you know it's all this all the same on your oxygen and your fuel so really nice set of regulators i like these a lot i mean to make it easy to get set up so there's a little closer look at the oxygen regulator now the fuel or the acetylene regulator is set up in the same manner you can see you have weld in the green you have cut in the blue and you have heat in the orange and they overlap here a bit it's going to be job specific on whereabouts you set it and then on your tank pressure gauge it shows you when your tank is full when you're getting close to empty or when you're in the medium range and then empty and it's the same on the on the fuel regulator as well so that's nice the way that those are set up uh foreign so so man that torch cuts beautifully i had the settings off just a little in the beginning but this is the first time i ever used that [Music] there we go and the circle cutters are nice but yeah plasma cutters are nice as well but you need to cut something round those will work for you so there is you a little better look at my circle cutting attachment i probably made this in an hour over five years ago probably so it's just a thrown together unit but it works well and obviously you could refine this a lot more than than what this one is but it has the basics and it works these are just sliders to keep your torch positioned at about the right height off the work this is your center so you just punch a hole that keeps you located you can adjust your radius by moving this in or out really simple shop project to make you can also buy them that's mine and it works because i don't cut a lot of circles but when i do it gets the job done so check out the new addition to the shop and i'm proud to bring this thing in here a lot of you guys already know what it is but if you don't it is a gerschner tool chest now these things are they're handmade and fitted right up north from me in ohio in the i believe the same factory that they've been made in since the early 1900s and you can still buy one of these today there's a lot of these out there and they're extremely well made tool boxes now you can buy one of these and people do to use in the shop every day as just your standard machinist toolbox and then some people will buy these to display in their house for jewelry or who knows what everything because they're just a quality box now this was a gift from my buddy ron white up in connecticut and i appreciate it and i've had this thing for about a month and haven't showed it because of what it had to go through in order to get to me and i'll tell you that story in just a minute i didn't know that i was even going to be able to keep this thing it was that much of an ordeal but let me show you the box then i'll tell you the story because it's sad to be honest but uh you know now it's part of the box's history i guess so check out how nice this thing is it's made of oak i think it was called tiger wood because of the unique grain pattern that this wood has a lot of stripes and stuff in it pretty neat all the hardware on this box is original it has been cleaned up ron is a woodworker he went over polished up all the hardware cleaned up the wood and it is in extremely nice shape for its age it's from i believe the 60s or the 70s hopefully you can see that grain pattern in this box now this is a well used box but it is in pretty decent condition the felt in it is original he did not want to have to strip that out and replace it and remove all the history from the box but you know as far as its appearance he cleaned it up as as good as what's needed now wood box is really good to keep your tools in because it seems to help keep them from rusting i guess it blocks a lot of the humidity that you would get in a metal box so look how nice that is put my machinist handbook in the drawer that is specifically designed for a machinist handbook and in the top of the box here he sent some of the things that were tucked up in behind the drawers from the original owner who's probably long gone by now i would guess so let's see i haven't even looked in this thing to see what's in it yet so just some dimensions from the from the guy that was gonna probably probably a project that he was gonna make cut up 21 and a half something some cut list a piece of high speed steel and i don't know what this oh it's a pull knob maybe maybe ron had to replace a pull knot i'm not for sure and then uh the key i didn't even look in that yet i wonder if it even works does that's nice a lot of times you don't get the key with them but you can have you can order a key the number is on the locks and you can call up gerschner and they will cut you a key and send it to you so missing the key is not a big deal so that is extremely nice let me show you a little better view inside of the top you can see they have a nice mirror there so you can check your appearance before you start working on the lathe so there's a little better look at the mirror and it's simply pinned onto the lid looks like either a stainless or an aluminum bracket a little bit odd to have a mirror in them in a tool box but if you think about the area that these were you know designed and built in people would wear suits and ties to go to work in a machine shop and you can see these lock these little spring-loaded plungers here these lock the front cover onto the box and they even go to the trouble to put metal uh inserts in the top of the lid that way these don't wear into the lid just a really nice box let me show you the tag on this thing and then i'll tell you the story what i know about the story of this box anyway so this is an item that i can't say well they don't make them like that anymore because they actually do they still make these things and you can still buy one brand new and there's a bunch of them out there you can pick them up on the used market i've seen people pick them up for 50 bucks you know people just don't know what they have or they're all dingy and dirty from years of being handled with dirty hands or missing some hardware which is not a big deal because you can still buy all the stuff from gerschner you know and replace it with the original original equipment so if you see one you know pick it up they are impressively well made so now the sad thing about this box is that it has survived since late 60s early 70s up until very recent with no damage at all and that's a testament to the build quality of these things because anything that survives in a machine shop environment for that long you know has to be pretty well made now chances are somebody fed their family out of this thing and you hate to see them get damaged and that's what happened to this one just recently when it was shipped to me from ron in connecticut through ups it just got probably dropped or thrown out of the back of a truck and got some damage that i'll share with you but and it wasn't because this thing wasn't packed well it was in a box that's much bigger packed in a box that was much bigger than this thing foam all around it top bottom the corners were reinforced with a cardboard reinforcing ron actually worked at a packing company so he knew he knows packing it was just total disregard for what was in the box during its transit here fragile stickers all over the box the shipping companies see those so much that they don't don't pay any attention to those they do absolutely no good so unfortunately it did get damaged in shipping and whether i fix it or not you know we'll see it's still kind of up in the air because it it still functions and i'll i'll show you how how badly this thing was damaged on one corner now the reason i haven't showed it up to this point is because i wasn't for sure i was going to even be able to keep this thing or not because of the insurance claim with the ups you know sometimes they want the item that's what i was told and i didn't want to show it if i wasn't going to be able to keep it so let me show you the damage on this thing you know it's unfortunate but that's just the way it is and uh you know maybe we'll fix it so i wish i would have took pictures before i snapped this thing back together but it is split all the way down this corner it tweaked the hinges on the top of the box this thing was crushed this way it bent this screw so bad that i had to pull it out and straighten it and to bend that screw those are pretty heavy duty took a lot of force so this thing was thrown out of a truck probably onto this corner and it was hanging open it was hanging open that wide this break now you probably i mean it doesn't look that severe but trust me it was pretty bad i popped it back together to see if it would still fit back together there was chunks of it laying in the box that i put back into place they're still not in there perfect but really what it needs is this part replaced and this side replaced to fix it back to where you know in unbroken condition i don't think that i'm going to do that i think that you could probably pull it back open you know line up the grain again and squeeze it with some quality wood glue there was pieces of this thing that i stuck back in there from where it kind of splintered out but yeah that's unfortunate that you know they they did that because it took a lot of force to break this box they're they're not put together you know flimsy so here on the workshop desk is where i decided i'd keep this cursing or tool chest i'm going to use it for some of my finer tools because that's what it's designed for there's not a lot of room in one of these but they'll hold a lot of nice small precision instruments i'm going to use it for layout just drawing light inspection stuff like that and decoration because it's good at that as well but you get the idea of a nice dayton ohio since 1906 is when the company was started and i think they've been in the same building since like 1915. they're still there still making these boxes and it's pretty impressive my buddy adam booth did a thorough video on gerschner he even went to the factory head a box of his reconditioned did a tour and if you're interested in that get in the youtube searches look up ebom 79 gershner and you'll see what i mean it's pretty impressive outfit so thank you ron i appreciate the box you keep your eyes open you know you can have one for yourself probably pretty cheap if you're lucky because there is a lot of them out there so in video before last we started tearing into the dual milling machine head here in order to clean out two oil fittings that were designed to take a light oil that had been pumped full of grease heavy grease in the past and were completely clogged up therefore the sections that they were supposed to lubricate would have never got oil again unless we did that so we had to tear it down to this point now that those are cleaned out what i need to do is change the grease in this power down feed gearbox and the high and low speed gearbox up here in the head because after 40 years it deserves a grease change and i've got some good quality stuff over there to use so let's get started pulling this grease out and then i'll show you what i bought to replace this nasty stuff with so so when you shine a light on this grease you could easily see all the bronze particles from those bevel gears you know just normal normal gearware after 40 years it's it's due for a change so this is diesel fuel not gas i just don't have a yellow gas jug so i'm just washing out the bottom of this reservoir i've got a pan down there i'm catching the mess in um not really trying to get this thing super clean i just want to get all the any of the debris and stuff that's in there out from the bronze gears and i called these uh spur gears it's a worm gear so while this gearbox is relatively clean and we can kind of see the workings i want to give you my best understanding of how this thing works now this is the gearbox for the power down feed so power comes from the motor down through this worm gear here into the shaft that has selectable speeds it gets transferred down into this shaft here which is connected to your handle and powers this worm which powers this shaft here that goes back and has a gear on it that hooks into the back of the quill and pushes it down so this is the mechanism here that engages the this worm gear to the quill so you can engage it and it hooks in these these teeth here which is also a slip mechanism kind of on a on a spring i guess so it can't it can't push too hard or it'll disengage or slip once it reaches the bottom where you've set on the front of the machine here it hits this lever which disengages and then you're free to raise the quill manually and reset so in a nutshell that's how it works but chances are your meal if you have one has got a very very similar setup to this you know they're not going to reinvent the wheel it's been around for a long time this kind of arrangement so there you go that's my best understanding of it so replacing the grease in this milling machine head was kind of a tough decision a lot of people had different opinions on what i should use it was hard to get a good clear answer there are a lot of options although you know a lot of those options revolve around how much heat that it's going to see how fast is the gears turning how much load does the gear see you know there's a lubrication is a huge topic and this is what i decided to go with the valvoline heavy duty palladium with the three percent molle now this is an lg number two grease that should serve our needs just fine in this gearbox it's not high temperature it's not high speed there is two worm gears in there that see a lot of shear and that's why i decided to to go with the molle and check out the molle if you're uh if you're curious for my best understanding it's like platelets naturally occurring elements really small and good for sheer or high load applications so this stuff should last and serve this gearbox for a long time the majority of the gears in there straight cut spurs but you know if you can go with the good stuff why not so this is what i chose now i went with the tubes because i want to use what's left in my grease guns and it's not that big a deal to spatula this stuff out and shove it in the head of that milling machine so that's what i chose to go with that's pretty good stuff so it looks like it's going to take about two tubes of grease for this gearbox about 28 ounces from the best that i can tell and if we use a little more than what they did originally that's not gonna hurt a thing as long as we don't majorly overfill this thing and that new grease is awesome it really clings to those teeth and moves up that old stuff had just settled all the way to the bottom of this case which this will do over time as well you know got hard now by weight i just took a male scale and weighed what i pulled out of here you know and then added a little bit from what would leaked out or what we lost just didn't get into the box so you get the idea it's close and that's all it needs to be as close this will last forever you can't probably if you barely had any grease in there at all it lasts forever so there we go so there we go i'll just kind of clean that up and that part's done so unfortunately that looks like it's it this week i was really hoping to get this thing buttoned up and all back together that was what i was planning but you know plans don't always work out in fact they seldom work out that's the way it seems anyway luckily no damage in here just common wear in the power down feed which they don't get used a ton anyway so i'm not really surprised it's good and i don't see any damage up top but there is a ton of grease in in this top portion that has to come out and there's no easy way to get that out of there other than one spoon at a time luckily you only have to do this stuff once so that's it thanks for watching thanks to my viewers patrons subscribers anybody who supported me on this project or my youtube adventures in general don't forget the thumbs up button it helps so that's it thanks for watching and i'll see you next time as the light leaves your eyes hold on to your dream oh i know you wanna scream since the day you're born you're just a flower on your own waiting for the sun to blow soon
