Toolmakers Adjustable V Blocks P1

[Music] you welcome back box tools I'm Tom so what we get here is we get a cool little project and this is a great project for you know beginning tool makers and I say that because it involves some some precision some grinding machine work just kind of overall shop skills but it's also I would say a forgiving project too so and I'll explain that a little bit more too so what we're building here it's it's actually a a training project that I designed I don't know quite a few years ago actually looked at my notes and I think it was 2016 or something like that and what it is is it's an adjustable well it's gonna be a pair of adjustable V blocks so the idea is that maybe you have a shaft in the vise or you need to change the attitude of a piece of shafting or a piece of stock or something like that and you can set these up and then it has an adjustment screw that runs the Vblock up and down okay pretty simple so it's got some interesting operations on here and we're making this out of tool steel so it'll be some grinding and some heat treating and stuff like that so it's it's a really good training project so now here's the funny part is that I designed this and I've never made a set of these myself so I figured you guys would appreciate going through that process it may be making some for yourself now I'll make these PDFs available to folks that want to build their own and that's all fine and dandy so it's all it's all been modeled up and and in fact I tweaked some stuff recently that that I that I wanted to change so got some stock cut here let's let's get down to it let's start on this and get going six so don't forget when you're done with that when you're done with the piece so left over please be sure to just take that opportunity to market what it is now I like to mark both ends that way if I do forget at least I have a second chance that I have a marked piece of steel so if it's unknown you got to treat it as unknown unless you're a one-man shop so good habit to get into the first thing we're gonna do is you know we got these saw cut and we want to just bring them down to our basic dimensions of the different parts and what I like to do in this situation is and I've already done one end here I just kind of cleaned up one end from the saw cut and then what I'll deal with that is set apart up just loosely like that and then set my stop like so that's why that has a flat blade screwdriver slot in and so then we'll but that properly now clamp and then we'll take a pass across there to clean it up no I got a fair amount of stock on there so what I'm gonna do now is without moving the the AXI at all I'm gonna take a measurement and sometimes you gotta get a little further out of the way and we'll just do a caliper one here so I got one inch 524 and our number is one inch one and a half is what we want so what I'm going to do is actually plug this number okay so I plugged that number directly into the Dro so now I can follow the Dro right down to my dimension now one nice thing about this particular project is that none of this is like super hyper fussy okay the only there's only one fit that really requires some care so and you get a couple chances at it is what I'd like to say and what we'll talk about that later so let's go ahead and and get these two lengths and get all the rest of these pieces to their nominal lengths and then we can start doing some real work here this is a pretty efficient way to do this if you got a bunch of pieces that sighs up here and you shouldn't be afraid of climb cutting it just doubles your opportunity to remove material [Music] there and I'm going kind of gentle here I could probably take this all off on one whack but no particular reason to do [Music] [Music] okay so the next these blocks here I need to take this this distance down here and I'm going to do the same thing on this DRO trick here is to I'm just gonna set I'm gonna zero the quill dro on the on the parallel oops that one make sure they're good zero yeah it looks good I'll touch a few places here so now like I'm reading zero on the on the top of the parallel when I come up my my quill dro actually reads the the dimension that I'm looking for okay so another little trick you know speed up these kinds of operations where you have multiple things to do and you know you can spend your time melon or you can spend your time measuring depending on how you want to do it these roughing in males really there's no this stuff the wait is a great way to use less horsepower to remove material to just a lot of surface area and these cutters [Applause] so I'm gonna lay out the V the V's and the notches and on this - and then I'll ban solve some of that material out of there and then mill up to the lines so this is this is this helpful when you have a feature that you have to locate all right so what's the next one for 50 you know when you're when you're when you're removing some materials so I like to do this this helpful helps me make less mistakes let's put it that way all right all right so that's the bottom that's the bottom we're gonna come up for 80 there okay yeah so I think we can put the we can put the angles on it now so what these are I marked the intersection with that edge where the where the 45 breaks out onto that edge so we're gonna use this little magnetic block this thing's pretty cool check this out it's an old brown and sharp magnetic block but it belonged to the curtiss-wright corporation that's marked it was part of their inventory I got it off eBay I thought that was cool I really kind of enjoy when there's those kinds of marks on things all right so we're gonna put that there like that and drop that in and we're gonna write mr. magna yes it helps if you put it on the right side there doping that's the magnetics okay all right like so all right and then I'll get a line going in here you get my magnifier cuz I'm old and blind I should be able to just flip this little know oh yeah I should be able to this flip it over all right symmetry there yep all right looks like I didn't quite go far enough on that okay there's that Oh setup works alright what that means is did I do that right one and a half oh I did do it wrong although I di I still need that see this is what happens when you're you're trying to shoot video and you're not paying attention I still need that that mark I put this mark in the wrong spot that's what I did 480 let's go back to that one [Music] [Music] [Music] so in a lot of cases you know band sawing out a bunch of material like this is is much faster than milling now in a couple small pieces like that like this that's it's a little bit questionable so you know this material that I took out of there right these are the pieces in retrospect I probably could have milled that out just as fast so me you know six of one half a dozen of the other but as the sizes go up this thin blade uses a lot less energy than than then plowing an end mill through there so there's big sections to chop off you can gain some big advantages by band sawing in this case probably not a big advantage it's probably a wash but but now we got it and let's go ahead and we can stack these up and well not like that like that and do a little milling on them and clean those sides up and get this thing going the bozo check well yeah I'm working both sides I'm working about the center line here in this case right so equal distances equal distances each way for symmetry purposes so I take it a quick measurement here there's a piece that fits in here that okay yeah we're still fine here so once again you know if you it's supposed to be 750 wide right so if you're a little wider or a little under probably doesn't make a difference because you're gonna make the piece that fits in there and that's what I mean is this thing this design is fairly forgiving there's uh there's chances to you know you don't have to hit everything dead nuts five okay fine [Music] [Music] what I'm looking for here and I'm looking for a blend between that surface in that line intersection and this is actually fairly sensitive when you have an angle there this particular angle is not anything super precision or anything like that it's just a [Music] you know a little bit more to the clearance for the the handwheel underneath we'll leave a little on there too we want to grind all the surfaces so they look really nice the other thing okay so we're just okay so now because of reversal and symmetry here I should be able to just pop this loose sure I'm clean and pop this in the other side like that okay double check make sure I'm not doing any bozo moves there okay come over here and mill with impunity back I'm just gonna do it all in one way here [Music] there's a bozo waiting to happen there I see that that's like really close to that corner there so I'm gonna pull it down on this side here make sure that I'm touching in the corner and on this nice flat here okay [Music] [Music] it's got to get close on this one and we're going to put it in that Center I'll have to touch the other wall he's get here pretty close okay we're gonna put our grinding relief in there and I'm just using this to even these two P two pieces up okay and then what I'm gonna do I'm gonna use an edge finder here [Music] so what I want to do I'm going to use the centering the centering function please of of the Dro so i don't even have to measure the piece to find the center or anything the machines don't wear the Dro is doing it for me so whatever's there plus half the diameter you have to think about the diameter that they use the center function okay and when I come back to zero right there that's the center so you know so this is two inch and five thousandths or something like that then it doesn't really matter because I'm in the center of the world there that makes sense okay there's our little we're gonna put a grinding relief right there some folks asked about this previously this is a Harvey tool in metal extension and this is an older one here it's tapered the new ones don't quite look like this I've had this one for quite a while so it's got a 1/8 collet here in a draw screw 1030 to draw screw 1/2 inch shank so it allows you to kind of reach down into some of these areas with small tools that are normally kind of hard to get to so they don't sell the tapered one anymore there it is right there part number 800 and it's a half-inch diameter shank Harvey tool Harvey makes some pretty nice stuff then I'll give those away by the way if you go looking for them okay [Music] you know what I'm gonna bring in close to the action here because this is just a itty-bitty little tool let's win this thing up a bit 2,000 rpm yeah so what I was looking for so you know what I was looking for there is I was looking for an equal mark on both sides that tells me that it well gives me some confirmation that I didn't screw something up that's you there on this and a compressor might kick on so I'm going to pologize ahead of time for that so this allows me to get in next to that wall with the grinding wheel and get that whole area nice and flat and that really looks like enough for me [Music] you [Music]
