I’m a fairly new Luther, just a few years and in on my 15th now but 13 of those have friction pegs.
-I case harden the peg shaft and hole after final reaming and shaving with ultra thin CA then shave again, then 2-3 more times with medium CA shaving each time as required.
-In your case I would have build the peg back up to round with coats of CA if it was not too out of round and do the same with the hole. This way your peg doesn’t change its depth and can be adjusted by adding layers of CA or reaming/scraping as need be.
-I do all the holes first for good measure and set the depth with a strip of tape on the ream. Then do the same with the pegs.
-I’ve found that with care all the pegs are interchangeable with any hole if one takes the time to be precise.
-String up for a good 24 hours or more and twist the pegs every three hours or so. The following day make any final adjustments.
*This is not for your guitar but I do something different with my pegs, I install mine by tilting the string hole end toward the sound hole about five degree. If you study the peg shaft angle, the reamed hole, and the string pull angle closely you will understand that the tension and unwinding also introduce a downward force that loosens the peg in the hole. By tilting the peg just a degree past 90 on the nut side of the peg we introduce an force that tightens the peg. I think this is about 5-6 degree and it’s hardly noticeable although the purest might be offended ;)
Well tended pegs are a joy to use but they do take some care to operate and maintenance by a skilled and experienced luthier.
My aesthetic sensibilities are offended by the look of the geared pegs, the mechanic in me is amazed, and my aging hands are looking up at me and saying, WTF is your problem ;)
Bravo for sticking with the friction pegs!
ps. On my instagram there are a number of posts about pegs, how I make mine etc.
