Serum,

Thanks for sharing. My father is also a precision toolmaker and until just recently when he retired he was the chief manufacturing engineer.

I worked with him for several years in various positions including quality control (granite surface blocks, dial indicators, etc., etc.) In the tool room machining parts to print specs using lathes, mills (horizontal & vertical), drill presses, EDM, and dozens of other machines both CAM and manual. I would kill to have a lathe & mill in my garage to make parts but my wife would probably kill me!

Cars were the same. I started doing tune-ups with my dad at age 7. I painted my first car at age 13 (and a 14 more before I was 18...all successful too).

Your point is well made on the steel set screw contacting the aluminum output shaft. It will deform with shock and general use and tightening it only solves the problem temporarily.

A potential solution would be to use a flat tip set screw or perhaps even a nylon tip set screw for secure attachment but without the deformation inherent in a pointed set screw. What do you think?
