As a rule I get my bearings from USA bearings 10 at a time, the crank I made from 2 dle -30 cranks, it worked out very nice.

Hi Karol right now this is just a proto type, I have some high hopes but untill I see and hear it run and get some data accuired I don't have anything planned out for the future.
I was up in the air about the width of the engine and was thinking about going with the 1/4-32 mini plugs, but for now I will run the CM-6 and go from there.
