That's a very good tip, thanks. I have lots of 12 AWG around my garageFor the size of most of the small work I do, I use the solid copper wire from a standard 12 or 10 AWG romex cable. The ground is easiest, but the white and black are also easy to strip out. Easy to bend it to hold on the jaws. Professional machinists I know usually have a couple of larger ball bearings with one side ground a bit to use for one side of irregular work.
