Toolmakers Adjustable V Blocks P2

[Music] all right next up we're gonna poke some holes in these pieces here and we're going to use symmetry into our to our advantage here I'm sure I'm in the right place so we're just going to do a little spot growing it will start to make more sense when Oh sometimes moving the part is faster than moving the machine to a new coordinate so on parts that have some symmetry to only you can take advantage of that quality got to be careful gotta be really careful ask me how I know that screwed up I'd screwed up every way that you can probably screw up on stuff like this [Music] all these holes will be counterbored here all we have to do is do the counterbore from the right side [Music] [Applause] we're going to cut these these little scallops here and I'm going to start with this annular cutter you can do this with a boring head and in fact we're going to finish him with a boring head but I'm just going to take most of the material out with with this annular cutter then I'll come in with a boring head and cut the correct radius in there they're just just slightly larger this is one in fifteen sixteenths I think and it's a two inch two inch diameter that we need clamp well and these are [Music] these are nice because they they don't care whether they they cut a half a hole or a portion of a hole or whatever and they make quick work out of it you'll see here finish even looks okay all these scallops do is when we have the the knob it allows a little bit of clearance to grip the knob and rotate the knob so I'll just turn this one around like so we clamp and I'm just hand feeding this you can feed it with the power feed to if you haven't tried these annular cutters you know let's see them you know for a reasonable price get a few and you may have noticed I have the second one over here and that's just the stabilizer set up a little bit here because we're clamping something skinny right to the make sure I don't trap any chips there we go alright so we're kind of ready to go here the way you set the radius here is you you know where the spindle centerline is right so you move off of a known edge that's that's a zero datum and then you run the boring tool over and in neutral like so and you you you adjust the boring head until you just scratch a line in some sharpie and then you know that the the radius that the boring head is sweeping is correct and then what we're gonna do here is now we're positioned over the the center of the desired radius and you can see that it's going to take a little cut right there so we should be good to go here I think I'm gonna try it in one in one shot and see see how it works here [Applause] some love on their behave there's I'm gonna shut the feet off and then I'm gonna stop it and then bring it back up because I don't want it to leave it oh yeah that's a nice finish I don't want it to leave a little spiral mark coming back up and then we just do the same thing turn that around and push it up to the stop lock her down okay and I'm just rotating it around so I can get close to the start of the cut engage the feed and you're gonna need a boring head to do this you can do it with a fly cutter and then you can just move the tool bit to the correct radius using the same map well we're putting this we're putting this chamfer on this this radius here and we're using a tool in the boring head that's good and I'll swing around so you can see it here in a sec you can see it so it's just a tool bit that's welded to a shank here you can weld high speed stainless or steel when you need to make something like this it's pretty straightforward so what we're doing in this case is we don't want to down feed with the quill what we're gonna do is up feed with the knee in this case because it's this does we get a smoother smoother feed and it's just a little steadier there's a big bird on there right now gonna knock out there it goes [Music] I'm looking at the big guy up chatter at the last bit there I'm just gonna go real slow on the last bit okay and then back it up support for it squeaks on me and a couple more and we get that this next one we're gonna do here is this the nut that's what I'm calling it and that's this bit right here in the assembly it's right here number five and this is actually threaded for the the knob here and it fits into a little recess here in the Vblock okay you know and you can see it's a small piece now it's got a kind of an interesting setup problem and I think I mentioned that I used this as a well it was designed as a kind of a training project and so this small piece has some little some little angles on it okay and it kind of like that right little reliefs underneath and it's kind of an oddball angle and it could be almost any angle it's kind of the angles irrelevant it's just to make it look more interesting okay that's all you can see here it's just so that it looks more interesting in there right you know it could be straight I just didn't want an edge a straight edge on one of these these corners to kind of come together right and still leave some some meat in the middle - okay so it ends up being this oddball angle in fact I've had a mistake on this that I had so the angle is here and it's OAD 8 by 200 which is twenty three point seven five degrees like I said it's kind of irrelevant it could be thirty degrees and then be fine or it could be 20 degrees and probably be fine - okay but we're going to go ahead and do it at the the angle that I set it up at okay and I'm going to show you a couple different ways to set it up that's what I'm getting to here with all this happen and several choices that you can make on how to hold this piece so that we can mill that know that little angle off we're going to show kind of from the simplest I don't know the simplest to the most complex I don't know I'm just going to show some different ways to do this so functionally what we're doing is we're gonna we're gonna hold this part at a little angle like this and then we're gonna mill that off that's what we're going to do and what I've done is a and you won't be able to see it there's a little scribed line that's a hundred thousands off of this edge which matches the the step in the Vblock that we're doing so that's my guideline as to how far down I'm going to take that angle but we have to fixture this at the right angle and ideally since we got one two four corners to do that it's a little setup and we can drop them in there and just repeat the operation right that's kind of the thought now that you know you can buy tools through you're blue in the face but a lot of these things you can do with with very simple tools this is probably one of the more simple ones okay is you just use this and then we can set that at that angle and these are actually pretty accurate you know if you use a magnifier and set these it's pretty good okay now you might go oh well how the hell am I gonna hold that up right well okay let's extend that a little bit let me grab a pair of some height let's get a little bit of height yeah that's probably about right okay so we drop that in there like that let's just go ahead and pin that up pin that up there with it okay make sure I get this going the right way like that okay you're starting to see the picture okay and now I would probably use a parallel that's a little thinner or I'd use a block across the top to to to catch that actually I probably use a parallel it's a little shorter in this case okay so that's one way you can hold hold that part right so you can do something like this and in clamp that part okay okay so that's one way super simple if you don't have a selection of these little protractors get some they're pretty handy for double check and sign bar setups and things like that so it's measuring tool angles that kind of stuff okay number two what's number two what was I going to Oh number two is is let me get number two going here hold on number two now remember I've tapped these these mounting screws just for these kinds of silly little operations like this or you end up doing weird stuff so we're just gonna can't get a parallel going here and I can still move so that's pretty close still oh actually I'm not gonna I'm not gonna use that so what I'm gonna use them to use this silly thing here that's what I forgot this is number two we're going to turn that on hopefully you guys can I don't know if you can see that but what this has the ability is I can I can set a zero anywhere okay all right so they're at zero now I'm just gonna attach it to that I'm eleven point four they say I was twenty three seventy five right twenty two twenty three to six seven eight nine let's go back a little bit eight seven okay so I don't think this thing reads and I just lock that down and now we can put that in there like so and what I probably do in this case here is do something like this so I had a little uh a little repeat stopper there right just to give me a repeatable stop okay and then and then clamp her up like that okay now this head sticking out so we need to we need to put some across there like that but then that gives you access to to do that work right these are either actually pretty good and they're handy for a little quick setups like this they're nine bucks or something like that and actually this one came from Harbor Freight I think it was a little more than that but electronic level with the ability to set a reference zero right is actually pretty handy tool okay so let's let me get going for number three I'll show you the the third and final way we're gonna do this so I'm a big fan of of sine bars and this is I think I showed these in a meatloaf a while back these are some swag items that I had laser-cut and these will be these are actually available for sale and they're five bucks apiece okay that's pretty cheap right so but it's actually a pretty damn good sign bar I checked them on camera I think and I was surprised how well they came out and so never feel like a sign bar is let's go this way here is too accurate for the job they're so simple to set up that's the one of their great beauties are the power of these right now I've already done all the calculations so and you know you take the sine of the angle and you multiply it by the the roll distance and in this case it's five inches and this is particularly set up to work in a tool room vise like this and you don't need gauge blocks under this end so what I generally use for you know run-of-the-mill work or it's not super fussy accurate as they use adjustable parallels which you can measure over with a micrometer now in this case I need a little bit more than I get out of that so this is already set just to save time here on the video alright so make sure that's bearing nice alright so there's my my little weird angle right and then what I'm gonna do is I get this little insert vise which is actually a real sweetheart for holding a little little cred like this so I'm going to do that and I'm just gonna use a little stopper on the end here to to set the and this is my only complaint about these kind of ices is the whoa the little chingus always drops out of the the Chingiz see that it's just it's just bad needs to be walked in there better okay alright so now I got it I got the plunger in there now okay so reference it and okay crank that down and then just to help support the device here drop it in there like so then I'll slide down until I'm sitting on the parallel and there we go Bob's your uncle yeah you can also use the level cuz this vise is magnetic you can use it right on right on the vise so you could just you don't need all this other business you can just twist this till you read the angle and then off you go so we can access that now and then we can flip it around without disturbing our setup and and do all four of those sites what we're gonna do here in a minute after I quit talking okay we got a cool little our fun little setup here and let's see if we can screw something up here yeah I'm gonna I'm gonna go at this I'm gonna go at this pretty easy you know we don't have a we don't have a death grip on this thing okay so I'm gonna be pretty mellow here for a mellower than my normal my normal self so what I'm what I'm looking for is this flat that I'm creating to to just eat that line that I've scribed on there my old man and magnifiers here to go there derelict Widow and then I'm gonna boy [Music] [Music] come back nice and smooth and then get out of our way I'm just gonna leave the cutter there is that level okay alright now let me flip that around and we'll we'll do that again I chickened out I used an L wrench on it I was just gonna use the screwdriver type I sure didn't move but I kind of chickened out say go for it one whack what do you think [Music] [Music] never cease like I might might even have you guys faked up I know what I'm doing huh okay alright alright so there's our little angle angle of the dangle there okay all right let me do the other one and then we'll poke a hole in the middle of that so that you get out the the thin parallels there because we're tapping a quarter-inch the parallels are eighth my normal parallels are eight and that's a half-inch wide so your your right knocking on the door they're asking for trouble actually you know what I'm gonna put this one on the other side here just for fun yeah they got two of them oh yeah okay so I mean Everett's bought you [Music] I'm not going to center drill car they gonna I got a good stuff drill here [Music] this drill was kind of dull me or I don't think I have anymore number three stub girls [Music] [Applause] [Music] [Applause] you go now you'd be a little bit careful when you're working with these thin parallels it's it's really easy because there's not much of an edge there to to get your part caught on the edge of the parallel so just be aware of that that problem and you know before you tighten that advice up fully cuz it'll put a nasty mark on your part now how do I know that I saw somebody do it once I'm still in the right place wonders never cease [Applause] I'm gonna sharpen that drill to felt kind of dull little lick of love there [Applause] [Music] you [Music]

I love this dudes channel as he has a lot of interesting machining content but damn I just can’t get over his verbal tick of “mkay”. I find myself ignoring his words and just waiting in anxious anticipation of his next “mkay”.
