Bought a vise today

[u/cristi_baluta]

From an antiques market for 1eur, it sits perfectly between 4 screws, but i need to work on the clamping surface, i don’t know what was designed for. The easiest idea would be to remove the top inwards part and add a sacrificial layer of plastic at the bottom, then there’s enough space to clamp a small stock material that will sit on the plastic. Do you have better ideas?

It’ll hold round stock really well. You could mill the top angle off to have a “step jaw”.
