Aren’t those springs? In your pic, they look like screws? I have seen that thing for a while now. Always wondered about using it on a really angled project. And having the project squirt out of the vise. I’m like you and use the round aluminum rod. Using a steel bearing ball is OK I guess. But I would be concerned about the divot/dent it can leave in your work and or jaw…DaveOk, I just took it out the box. I take it back, it's not ground. It's made for 6" vises so on my 5" vise it sits above the vise jaws slightly. One day I'll take it apart & mill it down so it sits below my jaws. Pretty cool idea but I definitely could live without it especially for the price it sells for. Oh well. I'll keep using the alumn rod that I've always been using.
I like that, but question, does it hold steady, being that it is round. Whenever I clamp round I wind up using a V block to steady it.I made this, from some 2" aluminum round bar , to hold tapered tubes for bicycle frame building, but you could use one half to clamp any uneven material in the vise. The V-groove is obviously not necessary for clamping flat objects.

It has worked well for me, but I haven't tried any heavy milling with it. I just use it to hold the tube for slotting or coping the end with a hole saw. Another framebuilder makes a set of blocks that has one flat v-block and the other round, but that forces the tube to be angled with respect to the vise jaw.I like that, but question, does it hold steady, being that it is round.

I'm pretty sure your fingertips to elbow, along with the grinding device needs to be calibrated.How are these very hard BB's flat ground ? I don't have a surface grinder and I would like the flat to be, well....flat.
It's said that the ball bearings do indent the work, so maybe I'll try brass or bronze (if I can find bronze spheres).
... If you don't want your work indented, couldn't you put a piece of square brass shim on the work? or will this affect "squareness" on the vise?
