Algodoo

Nice 👍

Thanks.

While inserting or removing the various shaped work pieces, if I happen to bump or nudge the small blue snap-in tips (I don't know the technical terms for the various components of the vise), the blue tips fly out of the yellow snap-in holders and float away. I was able to make the blue tips stay put more tenaciously by increasing the adhesion of the various components. You might have a different way to correct this issue.

Other than that, the scene works quite well. Nice work.

I paused the simulation when changing attachments. I was thinking that in real life they could be snap-in but didn't design it into the Algodoo scene. I was also thinking that the green, pink, and V attachments would be the only items a person would need to snap in and out. I don't see any advantage to taking apart the yellow and blue components. I just tried snapping the parts in and out. Snap-in works for some. Snap-out doesn't seem to work at all. I will update the description.

Thanks for the feedback. Sorry about the misleading description.

Yup, pausing the sim when changing attachments seems to work just fine.


This looks to me a bit like a low-resolution version of your "fractal vise".

Yes, they both work on the same principle. I was trying to make a lower profile and simpler version of the fractal vise. Also, the pink, green, and yellow intermediate parts could each have one center ball and three sockets on a common circle so you would end up with (27) blue pads. The fractal vise adjusts in 2D whereas this vice could adjust in 3D.

I like it. If I were into woodworking I would likely make one, but I happen to be mostly into metalworking as a hobby, and so this type of vise would not be precise and rigid enough for that type of work. It is cool though!

Would a 1/2 fractal vise against a flat steel jaw be precise and rigid enough for that type of work? If so, then would a spherical (as opposed to cylindrical elements)1/2 fractal vise against a flat steel jaw work?

I believe Kirk and other vise manufacturers already use a spherical element against a flat steel jaw in their vises. Even my Chinese mill vise uses that type of design. I believe that it's a better design than a simple lead-screw pushing against a flat steel jaw which tends to cam out of position when applying torque to the vise crank.

You may mean "Kurt" vise. A perfectly rigid and precise vise may not work as well as you would expect unless you are clamping parts that have two perfectly parallel faces. A vise where the linear guide angular play is slightly larger than the angle tolerance between the two almost parallel faces of the typical part would work better. Ideally, the moving jaw would conform to the part and provide high uniform pressure in the direction perpendicular to the face of the fixed jaw while providing high friction and high shear resistance in the direction parallel to the face of the fixed jaw. That's what I was attempting to accomplish with the whiffletree vise jaw. An improvement to the whiffletree vise jaw would be to have the elements return to their nominal position when unloaded.

Yes, of course I meant "Kurt". That's what happens when I try to compose a text message when I'm half asleep. LOL

Quote: "An improvement to the whiffletree vise jaw would be to have the elements return to their nominal position when unloaded."

I agree that would be an improvement. Probably can be done with 2 springs on each element that would force them into a center position when unloaded. Another possible improvement might be an over-center cam of some sort that would lock the elements in their loaded position. But that might overly complicate the design. Keep in mind: I'm not an M.E., just a weekend hobbyist, and so some things I suggest may seem silly or impractical to you.

Thanks. Good suggestion, I may use it.
