Re: CIM to 3/8" Coupling?
Andymark and Vexpro offer shaft adapters that take 5/16" keyed CIM shaft up to 1/2" hex.
My team has made similar adapters using 3/8" hex stock drilled through in an accurate lathe chuck, then cutting the keyslots through by hand with a Dremel. The 2mm key height needs to be reduced by about 0.01" (filing in a vise works) so it won't extend beyond the 3/8" hex.
How will your bevel gear set-up handle thrust load on the CIM?

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
