Think about it this way. No matter what gearing the output of a VP is spinning at, the input will be spinning at the free speed of a motor. If that coupling has held on at high speeds to motors for years, why would it fail now? I'm not saying set screws in general are the best idea, but the VP design is tried and true. The VP will also provide a much better supported output shaft than you would have otherwise.

This is a horrible idea. How do you cut a slot in a 3mm wide shaft? How big would the slot even be? Maybe 1mm?
