Tuning New Chrony, Opinions on #'s and Prod Regs

So that's a spring inside of the original hammer srping? What are the specs on it? On your gun I see the allen screw protrudes when cocked, is there some kind of stop inside that brass piece to allow for that travel? Thanks for the tip on the chrony, I'll try cutting off the fluorescent lights overhead and see if that clears up the error problem.
 
I'm not following how the allen screw in your gun is moving then. How does it make contact with the hammer when cocked. With the single spring how is that different from the stock set up? Is it a semi friction fit inside the spring on it to deaden the bounce? I believe I can make that part, I've used my drill press as a "lathe" before. I really appreciate your time and help.
