And the binding on 30s and 40s archtops - though not as commonly as the pickguards. Why are some nitro based plastic parts affected while others appear impervious to rot? Any ideas?
Is it worse if the guitar is often kept in a case?
The buttons on the tuners on my '59 ES-225TD are fine and appear to be original. I have seen others that are pretty bad.
seems most button tuners hold up fine
I think better than others though I've seen some that are really bad.
I bought a 1956 J-45 from Grun back in the late 70s (still have it). The tuner buttons crumbled after 6 months. I fitted Grovers, which is what you did back in the dayIme, the small white buttons on Gibsons will rot...I have replaced them on many Gibsons. In fact, I need to order another bulk bag of them since I just used the last.

I subscribe to the theory that when the plastic deteriorates there is an off-gassing and the off-gassing can accelerate further decomposition. Some ventilation might be advisable at least occasionally????
the worst being keystones ...small white buttons, I haven't seen any that were in near the bad condition as shrunken keystones
Mind sharing which brand of button fit on '50s klusons? My junior buttons just crumbled.
Also of note, I have '50s Kluson from before '59 where the original keystones are just fine.
I have. Far more round buttons used, but I have replaced them over 10 to 1 compared to keystones.
I'm sure a lot of vintage owners with shrunken keystones would prefer to leave them stock and not have you replace them
Tom...
RE: off-gassing. Somewhere I have a Vintage Guitar mag from the '90's that discusses celluloid deterioration and off-gassing....and they name the collection that was in a vault and suffered massive celluloid deterioration. I don't know what science was behind their conclusions or hypothesis, though?
Re: Drilling of replacement buttons. I suppose that I got tired of having buttons break. Perhaps the modern replacements are better sized, but when I first started doing replacements over 20 years ago, there was a problem. Dan Erlewine was the source of the heat treatment suggestion, iirc. And...the Ivoroid bottuns are harder material. They will burst everytime unless they are 'sized' with a drill, ime.
No matter...however the buttons can be replaced is workable, right?
