OK guys. I just checked, and there are lots of threads with flex shaft problems. Why did I check? Yesterday I discovered a family-owned and operated handpiece repair business in Brooklyn, NY operating since 1979. They service and repair handpieces for flex shafts, and the owner, Charles Stuart, seems like a really nice guy. Here is a screen capture from their site:
This was a real find for me, as I have been searching for a teeny tiny screw for an ancient Italian FARO handpiece. Lo and behold, they had it! You should really check out the website at:

It is quite a specialized business, as they deal with the handpiece only–not the motor. So it’s probably a good place to get answers to any problematic questions.…
