• Inspired to use soft jaws by Tom Lipton's Baby Bullet vise build: • Wilton Baby Bullet Build
• Explains differential screw terminology
• Explains how this design is adapted to a typical vise jaw
• Uses 10-32 clamping/differential set screw.
McMasterCarr: www.mcmaster.com/#set-screws/...
• Parting with a collet-stop in the Hardinge. Collet-stop made to accomodate pip left from parting. Holding the part by hand to prevent whipping (not recommended).
• Drilling and tapping the LH thread in the insert
• Cool-Tool 2 + Tetrahedral Boron Nitride
Unfortunately, Cool Tool 2 can't be sold in California. Also, I didn't find an immediate source of tetrahedral Boron Nitride.

I like how you want to have the correct tool for any given job, and are not afraid to make it, even to produce just a few parts. I do learn several new things from each of your videos, and your "best work" positive attitude is starting to rub off a bit on this old hack...

Rob, do you at least know it is unnatural to be able to drive two different Allen screws at the same time, inverted towards yourself, and at different rates? You've probably heard about the estimate of "10,000 hours to become expert" at almost anything, but you look like a man with 20,000 hours. Just phenomenal work and breadth of knowledge.

I hate those big azz counterbores in vise jaws... It's like the designer never used vise. When my wife first went to work for MSC, I was perusing the MSC 'Big Book', just to see what I could learn. I was checking out bench vises, and got to wondering what differences I could find between inexpensive and expensive vises. One thing I discovered which dramatically changed my shop life was expensive vises use Torrington thrust bearings instead of thrust washers. Inspired by thhe info, I decided I would upgrade my vises, to see what the difference was. I measured every vise I had, even on old Japanese vise which had become a doorstop, literally, about 30 years ago. I spent 10.00 on bearings, and swapped out 5 vises in an afternoon. My gawd, what a difference! Take a look at any half dozen used vises, and 5 of them will have bent and beat up handles, (the other vise is still the box!) They get beat on to tighten, and beat on to loosen. Not any more. With the Torringtons, all you have to do is give the handle a tug, and it will not come loose. When you're done, give it a tug, and it's loose. In over 50 years of working in shops, and around tools, replacing the bushing with bearings is the single most cost effective, and impactful upgrade I have ever done. Oh, the old Japanese doorstop? It's now a usable vise, and I had to find something else for a door stop. Try it, you will not regret the effort.

Could another approach be to cut blind key holes in back of jaws and still use same size access hole through to tighten? Then use a standard #10 bhscs in your inserts. Maybe even keep original 5/16" and increase access holes and of course larger key holes. Then you would just loosen the screws, slide jaws, and pull off.

Thinking about it mathematically, I'd put these kinds of clamping screws in the same category of 'true' differential screws. If you were to define the pitch of a thread in terms of how far a land moves with one revolution (or how far it will push an object for one revolution) right and left hand threads becomes fundamentally the same thing, the difference being that one has a negative pitch.

There are many comments about drilling through the back of the vice jaws. I can't help but think that either that would have to be done with a hand drill on the bench, or the vice would have to be removed from the bench and chucked up in the lathe or mill. Neither one of those seems as appealing to me as Robin's solution.

Nice idea using the insert screws. I suppose another approach would be to drill holes right through the vice jaw, counterbored at the far end where they come out, and use conventional socket cap screws the opposite way round into blind tapped holes in the soft jaw. Obviously there would be a (small) reduction in the strength of the vice jaws. But there is an in-between solution staying with your insert screw idea: Did you consider routing the access hole for the allen wrench the opposite way, ie through the vice jaw rather than through the soft/loose jaw? The strength implications would be negligible, I would think, and a smooth-faced jaw (whether soft or hard) is a fine thing.

@deeremeyer1753 6 жыл бұрын
Most people just pull the steel jaws and install soft jaws. Others use copper jaws that are "drop-in" and hang over the steel which provides a good solid backing. Others who do lots of vise work just have a big steel-jaw vice for bit heavy nasty work and a smaller "clean" vice with soft jaws. I don't think aluminum is really going to work too well for much. It doesn't grip too well.

Every other guy would have drilled from the backside... :-) But you found a way to leave the vice unchanged and remain compatible with existing jaws and have smaller holes. Concerning the differential screws I think this term is correct. It is just a special case where both pitches have the same value. The same is true for the rear axle differential in street vehicles which is also a special case (symmetric) of a general differential gear. We have commented about it in an earlier video: Your way to feed thin stock from the front side into a 5C collet with a back stop in it, keep the free end in your hand to avoid whipping, turn the part and part it off. It seems odd. :-) I have thought about it for a while. For small batches it has no disadvantages compared to the classic way of feeding from the backside. But I also can't see big advantages. It is just another way of doing it which works just as well for small batches.

@ROBRENZ 7 жыл бұрын
Thanks ER! My digital has 99 tool offsets. The drill chuck is tool #1 and is on center at X=0. I use an indicator in the lathe spindle to set center height and X offset once and then its good forever. Thanks for watching and commenting.

Just started watching your videos and really enjoying your work. Not sure I get all that effort to avoid a counterbore in the soft jaw, but that sine bar is really cool. If these were for the Kurt would you have fly cut them flat and square? Don't mind your fingers by the saw but that all long piece of all thread hanging out of the 5c worries me (as you said). And your collet tension sounded a little heavy :) Keep up the good work.
@ROBRENZ 8 жыл бұрын
Thanks Gus, I just don't like having to avoid the counterbore when gripping things. And I would have finished the faces if it were for a milling vice. I find that gipping a short length on all thread it pays to be a little heavy on the collet pressure to actually deform the crest a little. If you don't then the all thread has a tendency to easily crush into a barrel shape under side loading. Thanks for commenting and watching.

What is the purpose behind the long toolpost stud / cover? I was considering to drill through the vise (a bit ugly), or pin the jaws with roll pins when I get round to actually doing them, but this is a great idea. Not sure if the pins would've held when clamping on the edge. That drill chuck in the toolholder is nice. There are so many details I have to watch more than once. Recently I find myself wanting a vise with the clamping surfaces parallel to the table, not sure what I'll do about that.

I made an indicator arm that mounts on that post for all lathe indicating. That way I never have to stick a mag base on the lathe. You will see it in use in some of my next videos.

A complication is that if you were to build one now, you would have to get a used unit. That model that I think is a rebranded Ryobi is no longer made from what I can tell. Bosch made a similar unit too but it looks like it might also be discontinued. I am thinking the easier route if you wanted to start with a new machine. Is a benchtop belt sander.
@ROBRENZ 8 жыл бұрын
***** I do a lot of hardened tool steel work where I want to do a very precise chamfer after finish grinding. The abrasive belt works on both hard and soft material. The axial grind lay of the belt leaves no burrs on the chamfers and I can change grit size to suit the job at hand. If you do a lot of large chamfers > .06" the belt sander will NOT be the ideal tool. Most of my chamfers are < .03"

Also this whole swapping out the jaws of a vise is something I've wanted to do for a few years now, and after watching this I think I can do it. I do have a few questions, when choosing a soft metal, copper or aluminum, you obviously need to be concerned with cross contaminating the soft metals up against the steel of the vise, you used Blue molly and something else I didn't catch that you sprayed on to the vise, I want to know what it was, and lastly would that spray be the same material to be used for copper, or would it be different?

No contamination or electrolysis issues with jaw materials I am aware of. I think I used LPS3 for long term rust protection on the jaw interface

Is it a good idea to make a set of jaws with tapped blind holes in them and then screw them on to the vise from behind the jaw seats? Or replace the screws with pins, flush to the surface and press them in place (lot of work to undo though).

Hi Robin. I wanted to ask a question about the Boron Nitride you are adding to other oils and greases. In this video you called it Tetrahedral, but I can only find Hexagonal, Cubic, etc. Previously I had assumed Hexagonal is what I needed. Stan mentioned you also mix it with Dart CMD Extreme Pressure Lube for using on dead centers, if I'm not mistaken. Hoping you can clear up my confusion.

I should not rely on memory! Cubic is the abrasive, hexagonal is the lubricative also called white graphite. google ZYP coatings for info.

I am going to add an oscillator so the sliding carriage moves slowly back and forth over the full usable belt width all the time.

Enjoyed it. I noticed you milled the aluminum to length, but didn't true up the pieces facing the jaws (the backs against the cast iron) and the space (faces) between the jaws (facing each other where stuff is clamped). Is it just because they're "soft" jaws, so they're going to get out of whack anyway, and you'd never use it as a reference surface for measuring, so no point?

Perhaps a dumb question, but why don't they tap the jaws and put through-holes in the front and back of the vice? Surely that would be an easier way to avoid ugly holes in the jaw faces?

Nice job...looks like insert clamp down screws...seems a little small and wont last like the original, especially in aluminum. To accomplish your dilemma, [too large holes in jaws] better way to remedy this is to have blind holes in jaws, [no holes in front and no dirt getting inside] screw in from the back of vise, will hold better with same size as original.
