If you buy a bench vise at a discount store, it's not necessarily made for working with non-precious metals while making jewelry. You may need to smooth it in order to hold a piece of soft silver without marring it. So what do you do?
To solve this problem and have the best of both worlds by covering the jaws of your vise grip with copper sleeves.
- Anneal the copper to make it malleable.
- Cut two pieces of copper with the following dimensions: Width (equal to the width of the jaw) x Length (twice the height of the jaw).
- Place one copper piece into the vise closing it tightly.
- Using a rawhide mallet, hammer the copper down over the top of the vise.
- Repeat the process with the other copper piece.
