A bit of help please

Post by earlgo »

My friend bought these parts at a garage sale because he can't pass up a bargain. We had a discussion about what they are used for. I think they are milling vise inserts for holding small parts. He wasn't sure. I am sure one of you fellows know exactly what they are called and what their use is.
The thick edge is not perpendicular to the flat face making about a 95° angle with it, so if these are put in a vise with something in between the thin edges the vise jaws will tend to tip and push the part down clamping it firmly to the vise bed or whatever is there.

Any help would be appreciated.

There as you thought vise jaw hold downs Earl. In use the angle helps force the parts down and against the parallels. Starrett and I think a few other company's made them. Lufkin and/or B & S maybe? Today with most mill vises being or using some type of Kurt angle-loc design to pull the moving jaw down they might be a bit less important. Still a handy and useful item though. After a quick check apparently Starrett still makes there version. https://www.starrett.com/metrology/product-detail/54A

Yep. I've got a set, but have never used them. They are suppose to be handy for holding thin material in a vise.

Thanks Pete. My friend has a new Kurt vise so these may not be too useful as you pointed out.
