Starting to rebuild the Allen distributor machine

I was thinking of making a distributor machine for a while. So far all I got is an old small drill press (mount it upside down) and a large degree wheel. Need to figure a way to modulate rpms maybe with a small motor. Got the tach/dwell meter. Got a couple of old timing lights too.
This is great! I'm getting ideas (although some of this is outside of my ability to understand). One of these days i'll figure it out. (Kinda a back burner project). Like the mopar module idea (or the hei for that matter).
