→Friction pegs: Sorry, this amounts to "how-to" or prescriptive maintenance information, and we all know that "Wikipedia is not a how-to manual". Beyond scope of article. Your other stuff is good. |
Kind words, thanks! But dude, this is not a how-to, not even close; more of a cursory description. It's something that players find on pegs that have been in service for a while. |

Line 7:
Friction pegs are most often used on [[violin family]] instruments (not on the [[double bass]], which typically uses geared tuning machines.) They are also used on older instruments, such as the Bulgarian [[gadulka]] and the [[hurdy gurdy]], as well as on [[flamenco guitar]]s.
A properly working peg will turn easily and hold reliably, that is, it will neither stick nor slip. Modern pegs for [[violin]] and [[viola]] have conical shafts, turned to a 1:30 taper, changing in diameter by 1 mm over a distance of 30 mm. (Modern [[cello]] pegs have a slightly more aggressive 1:25 taper. 19th century and earlier pegs, for use with gut strings, typically had an even steeper taper of 1:20.) The taper allows the peg to turn more easily when pulled out slightly, and to hold firmly when pushed in while being turned. Since the typical wear pattern on a peg shaft interferes with this action, pegs occasionally require refitting, a specialized job which amounts to reshaping both pegs and holes to a smooth circular conical taper.
