![]() ![]() ![]() Then a screw and washer could be installed to provide a new bearing surface on the inside end of the base. I'm guessing that tapered diameter at the bottom of the post may have been straight when initially assembled, then peened to expand within the a tapered hole in the base? If you could remove that base, then the shaft could be chucked in a lathe (if you have one available) and a hole drilled at tapped in the end. Tapping in to the large diameter and installing a bolt as a puller may work just fine as well, but if you were planning to repair this one it seems the small diameter hole in the bottom would be the more important one to preserve. It seems finding or making some sort of expansion plug to grip the inside diameter and use as a puller would be least invasive, but may take a good bit of time to create and still may not be enough to pull past all the glue it seems covered in. I'm sure the existing peg can be repaired, but it would certainly be much easer to repair with the sleeve removed from the neck. It's a 19th Century instrument, and friction pegs do fine with light gauge nylgut strings.) (Please don't say I needed a geared peg anyway. (There's a lot of visible glue it's certainly not original equipment.) If forced to remove it, I'm inclined to tap a thread into the brass plug, insert a machine screw until firm, and heat and wiggle. That taper and the round little hole at the bottom of the base plug are visible in the photos. The end of the square shaft has a tapered round part, with the taper angled to be held by something in the base plug - now, presumably, worn and/or broken. The question is whether there is any way to make it work again, or is removal and installation of a new peg required? In fact, the knob and shaft assembly just slipped out. With the end of the shaft no longer held in the plug base (? - i.e., the brass thing glued inside the neck), tightening the screw on the knob produces no friction between the various parts. The square steel shaft simply came loose. An attempt to tighten a banjo 5th string, beyond where it had been before, produced a catastrophic failure of an old tuner.
