We are almost done with our first cue, not that I consider myself a cuemaker.
Anyway, 13-years ago I watched Chris Byrne remove the pin from my McDermot D-3, after I screwed on a 3/8-10 shaft with a brass insert.
Chris has this cool very expensive little heat gun that allowed him to remove the pin easily and quickly.
I didn't over tighten or cross thread anything.
Something must have galled with dissimilar metals because it was almost welded on and not coming off.
I didn't think to check it at the time but a couple years later here on AZ someone said they used some aluminum pins back then.
Chris installed a stainless steel radial pin, made a new shaft, and I called the cue a McByrne.
