I took a look at Mr. Google and see now what you are talking about Ed. Two pictures right out of the gate show the hold downs angled upward away from the base of the vice. Yeah, I can see where that wouldn't work out so well.

I bought a set of the Mighty-Bite fixture clamps for my mill table a long time ago. Unfortunately I didn't realize at that time that the type I bought did not provide any downward force to the part. I don't trust them.



I have seen similar types of hold downs as the 54's for magnetic chucks that have serrated cuts in the edges that compress against the work when they are pulled down by the magnet. Also seen that done in wood as well for preventing kick-back on table saws or joiners or something....

Sometimes I'm just leery of the "aspect ratio" of some parts, where you can only grab on 10% of the base of the part, and the other 90% is sticking up above the vice jaws. Kind of like holding a 12" piece of round stock in the lathe with 1 inch held in the jaws - and no tail stock. Somehow you just know something is going to go wrong.

That's why I'm wondering if these things really help - or not.....
