So a couple days back, I tried to put a hole in the CIM shaft corresponding to the position of the set screw hole on the Versa collar. This didn't work at all! Because I was using the Versa as a sort of guide for the hole I was drilling in the CIM shaft (and I did center punch it), I couldn't see that it was far too close to the edge of the shaft. By the way, the reason I was doing this was to put a roll or spring pin in through the Versa hole and the hole in the CIM shaft.

This resulted in a chipped 5/32" black oxide drill bit, a CIM shaft with a diagonal hole in it (luckily I was using an old one to test with), and all-around poor results.

Today I tried putting a tapped 6-32 set screw hole right on top of the Versa's keyway. This endeavor was more successful. The reasoning behind this try was that if we compress the key between the keyways of the CIM and Versa, it is less likely to slip.

Did anyone come up with anything similar? Did it work? Thanks a lot guys!
