Thats pretty much how I got the second one to go...1/4 turn in and 1 out to clear the thread. I've been a machinist 29 years, have tapped 10's of thousands of holes and this isn't happening with ball studs that aren't threaded to the end, or at least a thread runnout where the ball stud is slightly undercut. Tapping carbon fiber with a weak screw is a bad idea, the carbon turns to dust and packs the threads into a bind.
Thanks for taking time to write...misery loves company.
$33.00 later I have more ball studs coming, and another top plate in case I cant get all the steel threads out of the other hole.
