My teacher has Wittner geared pegs on her 18th century viola, which is interesting, as there are threads on v.com which complain about how intrusive and destructive the process is.
Hidersine do an off the peg geared-pegged violin outfit.
I asked their main setter-upper why they don't do a viola too, and they said they'd do one specially for me, but I've read poor customer reviews about that particular luthier, so I don't want to risk it, as the quote was about £700.
I'm sure Fiddlershop would be great at this.
The fact that Hidersine offer it as standard on a violin makes me feel it must be OK.
Or failing that, if it were so bad an idea, Wittner wouldn't be able to sell the pegs.
I doubt if geared pegs are glued in, and I suspect it's easy enough to reline a hole to reduce its diameter (or maybe you get peg blanks and make a peg with a slightly larger diameter). I guess you should email Pierre direct for confirmation. OK, you tagged him. Maybe he's busy and he'll respond in a while.
@Mouse - seriously, I wouldn't overly worry ( in fact not at all ) about installing geared pegs on the violin
I have NOT done that - but I HAVE used a peg-hole taper-reamer to fix seriously damaged peg-holes on an old fiddle I got from e-bay (along with a peg-shaver to reduce the new (intentionally) over-size pegs to fit)
I *believe* (could be wrong though) that one of the two main manufacturers of geared pegs suggest they are "glued" in - but - it will be a "breakable" bond I imagine - using appropriate glue should they ever need to be removed - probably (and I'm guessing) by a sharp tap on the far end of the peg - dunno for sure - so take this with a pinch of salt as they say....
As regards the widening of the peg holes by the reamer and possible weakening of the peg box again I wouldn't worry - (a) it is a TINY amount (much much less than the amount of material I had to remove on the old e-bay fiddle. (b) Peg holes that end up (eventually) oversize can be corrected by various means of bushing ( and re-drilling and taper-reaming where necessary depending on the type of bushing )
You appear to have confidence in your luthier - fire your same concerns at him, along with the feedback you get on the forum - I'm sure it would all be fine !!!
Good luck with the upgrade !
I seriously recommend not copying my mistakes. D'oh -
Please make your own, different mistakes, and help us all learn :-)
Hi @Mouse and others. Wittner makes theirs for fractional sized violins and they do not recommend glue. I mainly use Knilling pegs and, although they recommend the use of urethane glue, I do not bother with it. The shavings from hole reaming is very small, about the same as a pencil sharpening on an already sharp pencil. Oversized peg holes resulting from years of use can easily be bushed.
But I detected another issue from your original post that others have not commented upon. You are not availing yourself of one of the major advantages of the use of geared pegs by not removing the fine tuners on the tail piece. The lengthening of after length and weight removed may have a significant acoustic effect. No benefit if you make use of a cello tailpiece like the acousticus.
