I do basically the same thing. I got the first die from TCD and it was not the right size and it was set up for a clicker press. I specifically wanted a die 1 and 9/16 x 5/16 and just the bottom portion of the die, no handle or top portion. Then I welded a socket onto the die and I use my shop press to punch the slots. It goes through multi layers of leather very easy. I punch top to bottom. Only the bottom layer has to be edge beveled. I will try to post a picture of my set up tomorrow if anyone is interested. I vary a little from Denster process - I don't wet the leather before punching.
