I purcased this mold from a fellow CB member some time ago and just got around to putting my design thoughts into action:

The pin holes are not quite where they should have been, but a little time on the milling machine should cure that problem. The primary task was to figure out how I was going to hold and position the pins. I had pretty good luck with the Lee HP molds and liked their simplicity, so I used that as the base design for the handle modification:

I used the factory pivot bolt for the handles, then used a shortened coupling bolt to secure the handle halves together, which was locked in place with a setscrew. This setscrew prevents the handle nut from working loose and forms the pivot point for the HP pin carrier.
The pin alignment and protrusion is set by the pair of locking nuts on each pin. The pins were cut with a 5 degree taper and the bullets easily dropped off of them when the mold was opened.

And here is a picture of the results. The offset cavity is clearly evident, but casting the HP bullets was as simple using a standard 2 cavity mold.

Hopefully next week I can spend some time in the shop and recut the mold pin holes and make a new set of pins.
