Well, thanks. But actually, making a little mini die shoe like the one pictured is pretty straight forward if you've got a milling machine to fiddle around with. Every one is basically the same.
If there's anything complicated about it, it's the cavity. In this case, the cavity is a simple 2 diameter hole.
I make no claims about being a super dooper machinist, but I think I'm better than average at coming up with the simplest way to do whatever it is that comes to mind.
Basically because, if I can't come up with a simple way to do something,...I just don't do it.
