bent neck receiver + broken screw

Attempting to drill a hole into the original end of the stump very easily winds out that stump. 2 minutes at most.

"maybe 30 minutes work and thats drilling out the busted screw and retapping. "

Retapping!!!??? Why!

Hopefully the technician will have a replacement of the right thread, or one he can thread to the right thread (say from 10-32 to 8-32)

More time will be taken in re-aligning the parts the screw goes through.

I've often wondered why it hasn't wrecked the magnetism in that tiny motor inside my watch. Good advice. I've been late because of it, and nobody believed my excuse.

"The use of a steel sphere as close to the tubing diameter you use will give superior results"

Definitely. 1" won't do much.
