Placing Hole on curved surface

I’m sure this is easily done but I can’t find a tutorial that explains how to do it.
I have a ring (shaft collar) and want to drill a hole for a set screw. The best I can do is land on a facet. Methods I’ve come up with are very elaborate.

Just searching “hole on curved surface” off of your title gives several if not more methods.

I don’t mean to sound nagging. but sometimes it saves to search than waiting for a response.

Good point @josephkim626. This thread in particular.


My apologies!. I did my search in the knowledge base and didn’t give it much thought as to why there were so few hits.
