Toolmakers Adjustable V Blocks P3

[Music] we drill all the way through here accidentally crack at the depth so we're going to come up close to the notch but certainly not all the way [Music] [Applause] Zippity do that out here [Applause] we're cutting this little relief in the bottom this little steps has two bearing pads underneath it I'm sure we have to go on the right way and it's pretty I would say uneventful but the the only thing note here is that it has a 30 degree angle that blends to this surface here and we're gonna use a little be bit cutter you can set it up at an angle like that too and and mill that you can do it that way but I'm going to use a little D bit cutter because I found one that has the right angle on them so all right check my yeah that's good so this one is fifty five thousand steep I'm just gonna go about forty to start with Niagara stabilisers Denis Nolan gave me he's saved a pretty awesome I've been using this one for quite a while actually and it's just hanging in there [Music] so fifth year and we'll leave a little bit for a finish cut [Music] and I want to use a little bit of oil and it gets a nice finish that some liquid love [Music] we got it here bring that down so you can see it this is a we call it a debit cutter or I don't know it's a single flute cutter that you make on the deckle or debit grinder and you split around [Music] tool in half around shank in half and then you grind a profile a desired profile in there and they're really handy because you can put oddball angles oddball radius you can make full radii custom sized ball in Mel's so they're used a lot in the mold and tool and dye industry for stuff like this now we're gonna put this this little 30 degree lead in on on that edge and what I want to do is I don't want to drag across the bottom so I'm going to touch off on the bottom and just zero my mic will read out and then I'm gonna come up like a sow okay just know just so I leave a nice scratch like that in there all right I guess I didn't get a good bit well I guess I'll be grinding that to the surface huh well I was gonna grind it anyway but come up for whatever reason I didn't get a good good zero there okay and I'll just do one side here and go to town you know you can't hog material with the single flute the single flute cutters and you know they only have one effective flute and you got to feed him real slow to get a nice finish because they're they're slapping away like a fly cutter bit and but you can their advantage in a case like this is you can get any profile you want and like I said before you can you can stand this up and do it with a regular end mill - I'm just doing it this way because they can [Music] there it's going on there [Music] and what we're looking for we're just looking for a good blend in those intersections in this case it's just the with the decorative little thing [Music] will that off you get a look at it yep I'm gonna stop there and then you know you can check it with a something that's got an edge right and see if it catches in the Dozen here [Music] [Music] and I kind of know what my number is in case you're wondering all it every time [Music] and they're closed now [Music] [Music] my number [Music] and feed real slow Bob your uncle [Music] yep just whip it's just like a slide there does nothing catches you don't feel anything all right so we're gonna smack some champers on here on these corners and we just have a four flute 90 degree chamfer mil in there and what I like to do on chamfers is I use a fence I guess I call it a fence or just a reference hedge for all the edges right so in this case it's the back jaw the vise there so we'll make a cut to make a cut and then we'll close the vise and then we'll cut the long edges but I'm always referencing this fence so the height the height of the tool in the position and in relation to this edge is what's important and I I just keep going to the same numbers as opposed to trying to work it out and match match it on each edge now this is manual work okay see and see it's like you know it's a trivial thing to drive around that and do that okay but what you want is you want these to match up real nice and so they look good because if they don't they it's they stand out pretty badly okay so let's just go ahead and we'll do a couple here I'm not going to torture you with watching all of them here and I've already you know I did one so I'm going to back off I'll back off some amount that makes sense for leaving for a finish cut right and then once again with chamfered tools you want to you want to feed them slowly this thing you get a nice a nice smooth finish you feed them too fast the look Nachi okay so there's one all right okay and then we'll flip it around and do this edge since the vise is already open to that that dimension and back off a little bit make sure I'm back mr. ruff you cast I can feed that faster by hand I'm taking a fair amount off feedback by hand well the main we're using that single edge is our reference that's the main thing at for these parts to do and they have a little groove going through them these are the verticals that the V blocks run up and down in and I kind of want to do them all together you know run the slot all at once this saves work but some of you may have experienced when you when you put some parts in if there's any kind of minut variation in the parts width wise you don't get equal clamping necessarily on the part right so this is always a danger when you're doing this kind of work so there's a couple ways you can handle that one is you can use a little bit of paper you know you can cut a little strip of paper and put it in there and then that helps take up any of the anomalies between the parts now these they should be pretty close okay but there's no guarantee that they're exact right and you don't want to find out the hard way right my preferred method in this case is they use a piece of this is aluminum welding right here you know TIG welding ride this is 40 43 I think nice soft stuff and what I like to do is those are slightly magnetic up in there oh I see what's going on I got the I got the rubber band on the okay now what let's let's regroup there the the parallel is they're moving out of the way can they get the I got the rubber band on it right so let's let's try that again bring this up close like so okay and then what I'll do now I don't have the rubber band on it so the parallel will stay there now okay so what I'm gonna do is I'm gonna put this between the vise jaw and the part here nice and high okay and then what I'm gonna do is clamp that and what that does is it it come it compresses this and flattens this aluminum welding rod and takes up for those anomalies and I'm going to smack this down a little bit too and since it's round you know it's a point in point contact so it deforms a little bit real nicely so it finds a good equilibrium this is what I'm trying to say there a lot more words okay so now this is a pretty safe and secure setup here and I still have a good a good datum reference against the side and to do the milling anyway that's what we're gonna do without the rubber game zero now this is an anti bozo move because I know myself pretty well I get this this rod sticking out here and I just cut it off with a pair of pair a pair of cutters so it's just it's just waiting to it's just waiting to stab here's scratch me or gouge mirror poke my eye out horrid right that's better and put it this way well it won't quite hurt as much all right so let's let's take a fifty thousand Scott your debt looks like pretty friendly chips look good this is one of those Niagra stabilizers again I'm gonna increase the feed rate a little bit okay the chips change color a little bit when I increase the feed rate at least I think they did so we're going to machine the width of this slot less than the width of the Vblock that way we can grind that those sidewalls so they're nice and straight and smooth and all that nice stuff all right not another the see those n melts is cooperate look along pretty is [Music] imagine Armand see where we're at so to do that we're gonna use is I always like to measure this kind of stuff with an adjustable parallel because it really you know you can wedge it in there nice and tight and you're pretty comfortable you got a good you got good contact in there and then you just measure over the top of that with a with a my kilometer here all right 485 okay I'm gonna go a little bigger than that and question is how much well grind we're gonna grind this first when we grind after these are hardened well grind this first so that they're all cleaned up and nice and basically phenomenal the pieces that slide in here are over thickness but getting the thickness to match this is easier than getting the width to match the thickness I hope that makes sense so that's what we're gonna do [Music] I'm just moving over to I should have done this from the beginning but I forgot but at least I remembered it's better if you do this first then I forgot this is a anchor loop here [Music] one characteristic of a - it's a little interesting I always think right there okay is when you use these spiral flute apps the material is not real ductile so it tends to break up into little chips and stick to the tap so you can kind of get away with power tapping pretty deep I guess is part of it you know the chips break up into small pieces which is make a curly stringy chip you know like you would in mild steel or stainless or something like that [Music] so here's the setup for putting this little angle on the on the vertical guides here and amusing this is actually an interesting little sign bar I got off eBay I was gonna do a restoration on this one and it's it's nicely made and it's actually pretty pretty accurate I checked their roll centers and they were pretty good it's getting a little bit of corrosion on it so it needs a little rehab but it still functions fine for this kind of application the reason I use this one was it has a little stopper on it and it's a little less than 1/2 inch which fits us this groove here and so we get a kind of instant stopper out of it anyway it's just this happen to be kind of right for the job here and so it's all excited this is typical of me right it's all excited that I could use this tool I was fiddling around with it and I chased all the threads so I could move the stop around the Delta and then I went ahead and milled one right you know I thought came out great and then I realized oh you dope I forgot to do the and you know this is the danger right there's a little grinding relief that goes in in these corners here right and it's actually a hell of a lot easier to put in when the thing is is orthogonal like this and not angled now it's not the end of the world I I realized that no way all right what do I do and I went and looked and I got a way to hold this that's not too that's not too bad that'll be kind of fun too to put those those little corner reliefs in there for the for the grinding so we're gonna proceed with this operation here okay and you see how it goes up against the stop there real nice and then we get it get a nice amount of clamping still push it down a little bit on that snag it down okay and we're using this big roughing end mill here although it leaves a nice finish on the bottom that won't take much to grind off after the fact okay so let's go ahead and do that [Music] hey I got a little little witness mark they're hard to see be able to see it on that one just to you know it's a kind of a oh oh he'll deal there alright let's go down with it about 5:00 I'm just going to put a little liquid love on there drop it down speed it up a little for the finished ass speed nice and slow I don't leave a bunch of lines in it does this cutters moving pretty slow so [Music] [Music]
