Are you using the cap-head screws just as set screws? How well does it hold the die tops? Do the tops ever work loose?
I had thought about doing something similar with pins in the die tops and cap-head bolts coming in from the sides of the bottom die. However I was worried about the tops coming loose and my idea of a fix was going to be to ream a taper hole in the pins and then turn a taper on the end of the cap-head screw so it snugs the tops down as you tighten the screws. However it would make for more work when making a new set of tops.
