Toolroom Vise V Block

[Music] welcome back doc stools I'm Tom so today we're gonna you know I've been doing a particular V block operation in the the tool room vise on the mill for a thousand years finally got around to making a proper v block that mounts in the in the vise so we're gonna take a look at how I've done it before and how the what the new block does it's different and makes the the operation better so stay tuned let's take a look at this thing so what this technique is about is standing something up in the vise to do some end work on and something that maybe isn't the kind of favorable for gripping between two parallel jaws a round would be a good example right so we put this round in here like so you know it really is just touching on two little points right and it's you know if you try to mill that it's a problem and then the other problem is you know making a square with the world so you know my solution has been to use a decent v block here and something like this and I will talk about these in just a second and this pop that in there like so and then you get three point contact right boom one two three right it can't twist and it's automatically you know if you're vblocks any good it's automatically squared up with the world so you can indicate this and drill or mill or whatever and it works for rounds and squares and rectangles of you know reasonable size range now let's talk about the blocks here so this is one that I modified a long time ago and it started out as one of these here now this is a brown and sharp 7 750 B and and they have a clamp that slips in here but I don't use it anymore and you can see this one's been shortened a little bit right and my recollection was this end of this block was pretty pretty chowder DUP and I just chopped it off with a cutting disc and got it a little closer to the same height as the as the vise jaw here right okay and then this guy here this is the starett version of the block just slightly dimensionally slightly different and you know this subtly different and then the starett is interesting because it has a it has a capped hole in it that allows you to use it for creating a kind of a temporary fixture and whatnot so the starett's are kind of loose - that's a brown and sharp Lufkin made these - you can find a single block like this on ebay for you know if you hunt for a while and you know you can find one that's a little stained or whatever for 20 bucks or so okay so this sits on the these nice pads here and then what I usually do is this kind of lock it in with these these parallel clamps like this so it doesn't move around so if I'm swapping parts out then the block doesn't move and I don't lose money I might might date him so works fine I've been doing it that way for gajillion years but I decided finally to create this block here that actually mounts in here and it's kind of designed with this in mind so let's let's go through the steps here and and see how this is a how we made this and and how we got how else we can use it okay so let's let's just kind of go through how you can use this block now I've tapped these fasteners for for 1032 so and I counterbored those you know we can not that with a socket head or if we're not doing anything too radical we can dismount it with a couple of thumbscrews real quick and no tools kind of walk that sucker in there okay and then now our blocks in there and Bob's your uncle no I think you know what you guys already seen it so you people are going wow what are those tapped holes on the sides for right so let's just take a look at how that that might be used and my act together here let's do it like that let's put this little guy in here and what we might we might do in this situation here just something crazy like this and then these you know the heels of these strap clamps from my mini pallet are tapped so you can do something like that right now in this case I think I wouldn't let's go a little high lock it in so in this case you know you could do something like this right and and then what you could do which might be interesting is take this out and go to another machine surface grinder or you know change the orientation without losing your your datums and whatnot where you could just use it as a kind of a regular Vblock - okay anyway another another way you can use it I just love the smell with stuff this brings back memories hope they never change the formula let that dry for a bit then we'll do some I'll get some layout on that hey I didn't even get any on me all right yes sir here's our drawing here and I'll make this available to people that want it as a PDF or maybe a model I don't know I have a bottle too yet it's just a 2d drawing right now but what I did is I just kind of calculated up the the different intersections there to help me do the layout so we're just going to scribe this so we can be inside that's kind of the my preferred methodology on this kind of stuff just remove as much as I can on the bandsaw first and kind of get the material out of your way right and do it that way so 751 inch 362 is the next one so I'm you know I just kind of sped up the operation by make sure you did it right I'm paying attention and then I'm just gonna saw close to the lines 563 I gotta pay attention here a little bit it's 200 thousands more and then the center line I think is next yeah two-inch 438 to arrange for the okay that's our center line so I'm gonna take that all the way across the block and you know what I did not look to see if you guys can see the scribe lines there you're not seeing the scribe lines very good I had the exposure turned down so you could see the the white paper so once again one of the challenges of filming on YouTube is a dynamic range of the photography that you end up doing so I'm just gonna that's our our groove there to a half there see the side of our relief groove alright anyway you get the idea so let me get this laid out and then we'll do a little band song on it transfer some of this stuff down center line okay so this line is the overall thickness so that makes any sense to you guys at this point but these are big V and then oh you know what I need yeah I forgot that choice half the H all this do it let's do it the old-fashioned way here it's like oh yeah I miss I missed one all right it's 4-h 125 yeah it's okay we have the technology here okay and the next one is that that two there I always like the the kind of the drafting aspect of layout like this you know all these intersecting lines okay so there's our outline and then this is our little of our little grinding relief there all right so we have enough to to do some serious band sawing there and and then we can do some rough machining heat-treat and then grind [Music] [Music] [Music] [Laughter] [Music] pretty good pop that with what up yeah of course [Music] [Applause] [Music] at this point I'm just getting close to the lines and visually there and then we'll do some measuring and we want to leave some to not that it mattered that much but we'll leave some for grinding after he treat [Applause] [Music] [Applause] [Music] [Applause] [Music] we're going to use these these add-on jaws here and these are for holding stuff at a at a 45 degree angle kind of like this right and the way these mount actually I don't even have to take the my fixed jaws out what I've done is drilled and tapped the mounting screws in the center for a 1032 in this case stick appliances on there without having to actually remove the hard jaws so so I'm just gonna install these or this ones I kind of I already locked down the the on the moving jaw here and there's no particular reason you see there's a little bit of wiggle so what I want to do is put something in there that's kind of a known square right and then use that help okay we're still is use that to help kind of align the jaws right so that seems nice and settled so I'll clamp that and then now all this tight needs up a little bit and you don't need a lot on these are just mainly the locate parts actually these screws should probably be a little bit longer than you know this is okay so now this kill myself line there so now I can just kind of plop this in there like so and this is this is not a new idea folks so but perhaps the the mounting scheme is a little new but [Music] not particularly new okay so now I can work on this surface and they can work on this surface and then what's nice here is because these are fixed right I just flip it and I'm referencing the ends so everything there's symmetry okay this is a common practice in grinding and some machining operations where you you flip and then you maintain a symmetry so what we're gonna do here [Music] [Music] [Music] [Music] to only grind this what we really care about is the perpendicularity between these surfaces in in the bottom so when we put things in there we want to make sure they stand up square that's one of the uses of this technique you know if we're holding stuff in the vise so when I clamp a rod in here I want it to be straight up and down with the world anyway that's the goal so okay so now I'll flip this over deeper this that sits in there nice and then I'll go after those other two that's flat [Applause] [Applause] [Music] the well this is the grinding relief so I can get in there with driving or not or and I put that on sinner what I did is I picked up both sides of this and and once again cemetry picked up this this went to the center of what's there the material that's there [Music] [Music] [Music] [Music] would use counter boards like this bottom um in the in the Chuck that's just a good a good habit to get into so I'm gonna set the quill dro here I'll make this like cream cheese and then always you know your stuff like counter bores I always run them in countersink seemed like that you generally run them kind of slower than you then you need to that way they just kind of last forever heart yeah buy new ones and these particular counter bores are a little bit looser fit than then you might do normally right this is a Phyllis Tourette counter bore here so that a point by grind some material off of the reference surface the screw holes will still line up we're doing now is I've got a little basically a little relief in this backside here where this material is just relieved a little bit so that there's to basically bearing pads bear against the vise so all set hello here I'm just gonna define the edges of it right now this this helps me sort of pay attention to make sure I'm doing it right I'm just gonna dig a real light pass across pretty close to my finish eggs same thing on this side so what this does for me is [Applause] this gives me a nice visual and now I can go down and take the bulk of the material off and not have to look at numbers I can kind of mill with impunity I guess it might be how you would put it so I got a nice edge [Music] we're ready for our finish pass now I'm going to go down to depth now right there and I go to my number not a precision feature [Applause] I just want kind of a decent finish on that I'll probably grind it'll you know just to take the toolmarks out of it after it's be treated [Applause] and I added a little bit of oil just to improve the surface finish for the finish passes for people in wanting why I didn't use oil previously [Applause] so that the mantra ruff ugly you know roughing can be ugly there's no no requirements on surface finishes and things like that while you're roughing the point is to make good parts in the end right so how you get there is there's lots of ways to do it [Music] [Music] [Music] this next bit so these are pretty much all the features in this in this block here are this V block I do in the drawing I have some holes here there are nice round ones anyway that are kind of in the middle of this mass here and what I did was I just I drew a circle that was tangent tangent and tangent you know like this and then at the center of that so it's kind of in the center of that mass there is a the reason for that now these are kind of optional holes and the reason for them is you know to lighten this up a little bit and you know I don't they don't have a specific function I guess is what I'm trying to say so I kind of don't need to put them in there but I kind of want to put them in there to just make this lighter and I don't know all the tool makers out there will know that you know you start getting enough stuff like this in your toolbox and your toolbox gets pretty heavy right now that said I'm probably gonna go ahead and put those holes in there and then this is a juncture where you can think about other uses for this block right what you might use or might you might what might you want to anticipate right so I think what I'm going to do is I'm going to add a series of tapped holes in these flats here on both sides like that and what are their for I don't know the first thing that comes to mind is maybe I want to use something like this on there right and I that's a little too small but I got a big round in there and I might want to hold that in and take this somewhere else or hold this in a certain way or create a stop or I don't know right so the features are almost free at this point right they add these holes like I said these don't have a specific use other than to take some of that mass out of there it also gives me a place to drill into so that I'm not dealing with blind holes too you know I'm just what I'm trying to do is I guess is uh you know before you finish up and get all you know start shaking your hand yourself right let's think about potential other uses for the thing and you know this doesn't certainly doesn't hurt anything and oh wow it would be really handy to have a little stop like that because you're gonna know what you know you're doing something else yeah that's all I'm saying and I said it [Music] so I'm going to step these up and then I'll run the boring head through it just to get a nice finish on those holes so you know it's something you'll be able to see so it's got a scraggly finish in there it's not so cool [Music] [Music] and maybe I'll run a reamer through instead it'll be faster yeah dreamer just run it through there um I power fed the the reamer for a nice smooth finish see what it looks like here oh yeah that looks pretty good it takes a little longer you know cuz you'd probably feed faster by hand if you even if you were trying to go slow let's do that again game speed and off we go where you can see that oh yeah that's sweet finishing there [Music] so whenever you want to do nice countersinks put the put the countersink in a college don't run it in a chuck because sometimes you get wobble and makes your counter Singh look like duh but I think I want the holes in the middle of that other hole I'm just gonna pick this pan up get on the center of that pin [Music] yeah over all right so that's the middle of the pin there okay let's see what are we doing here yeah okay let's do er let's start from the other side now I remember the numbers at least it's double check make sure that's a zero yep that's a zero alright so for that it's very close to the edge you know second-guessing myself originally I had the whole quarter inch from the edge I think I'm a ghost let's keep that over there drill head I know I want one in the center and I want to to the outside this is half inch white here so do I want that right on the edge or they wanted in a little bit I say in a little bit yeah [Music] [Music] [Music] there this is the anti bozo double-check that the math in your head was correct right 1:10 okay so this is a it's a counter drilled tapped hole you'll see that see that in a satirical it's all this do one complete for you okay so we're going to go through that's our tap drill hole and then I have a counter drill hole here so this is a little bit bigger than the then the body of the of the screw and the reason for that is in heat treated materials it's really easy to to pull a thread up it's really easy to pull up a thread so what you want is you want your you want your threads to be subsurface if that makes sense right you don't want the threads breaking out right on the right on the surface [Music] there you go okay so hopefully you can see that so the so the threads start below the surface right so if anything lifts up it it doesn't raise a weird bird anything on the on the surface and that's the reasoning behind that that's all I'm saying [Applause] [Music] [Music] [Music] you [Music]
