Again weekend, again some beers...
Litle more about stamping here. After ring parts has been die struck they need to be cut off excess. It's beeing done with stamping block (don't know if this is correct name in english). They need to be made for every part new. That's not cheep at all. If you do not have such blocks and the press for this (diferent type than used for die struck) you need to saw every part and finish by hand, that's more labor than finishing casted rings. Below on pic is one such block , not for TK ring, (at home garage this is the last left, ring blocks are already at new home) Hope you get idea how its work. This is bit more complicated three stage block (at one stroke it makes three operations) was used for reenactors silver dog tags.
