[TheForge] Need some help please

[Barking Crow]

I need to make a cup washer for a post vice I'm restoring and don't know how
to do it.  I need to make the washer that fits curved side against the ball
of the screw that the handle goes thru and fits flat side against the
moveable jaw.  I think I've seen directions for making one somewhere but
can't, naturally, remember where.  Any help would be appreciated.

Thanks,  Jeff Valentine
