My customer gave me a Cuetec shaft with the insert damaged beyond use. I used a damaged Cuetec shaft that still had a good insert as a donor to repair my customers. Will be testing it out tomorrow. I’ve had this repair done by a now deceased cuemaker, and I’ve been using the cue for 20+ years now without a problem, so I expect it to test out fine. I’ll let you know if it does not. My tool box is a little short on taps at this point, so making a new insert was beyond my ability (tool wise) at this time. I let my customer know before I did the job that I had other Cuetec shafts I could sell him if this did not work out, and he agreed to my terms.
