Another aspect of the luthier trade of which I have no clue.

I would like to create a gently sloping dome end on my pegs.  I thought of three ways where it might be done.

I could drill a hole at the center of a wood plug, ream it with a peg reamer, insert a peg and file it in a lathe (the plug diameter being larger than the peg flattened projections).

I could cushion a piece of sand paper on a wad of cloth and hope that a curve would form from the deflection in the sand paper when bearing on it.

I would try to place a piece of adhesive backed sand paper in a small soup dish and sand in a curved peg end in this manner.

All this is theory.  Any wisdom from someone that has actually done this would be appreciated.

What's the advantage you see to having a dome ended peg?

Mine only stick out 2-3mm from the side of the pegbox and the perpendicular cut to the dowel has been ever so slightly sanded to avoid a rough edge.

--  @Irv -that's what I did (red highlight) - seemed to work just fine.

@bocaholly - makes no odds really - it is (I suspect) simply aesthetically pleasing, making the peg protrusions look just like little "bumps" on the peg box outer walls.  I mean, that's fine when the pegs are new, but they'll eventually (over time) wear-in and protrude once again - mind you - if driven by some sort of compulsive disorder, you can always trim them down and round them off again once every few years of adjustment ! LOLOL  -  P.S.  I only bothered doing it since I have gone the whole-hog and reamed out a pegbox, shaved the pegs and cut them to size, then thought  - Oh - let's make it look pretty !  The sandpaper on a cushion of towelling worked fine !

I seriously recommend not copying my mistakes. D'oh - guntohead.JPG

Please make your own, different mistakes, and help us all learn :-)

thanks, BillyG... I'm not that OCD 🙂

Love the way my pegs look but I keep coming back to the idea of Wittners. one day maybe... but by them I might get the gist of tuning while holding my violin in playing position!

Thanks BillyG.  I generally just saw off the exposed ends of my Knilling pegs, but I just purchased a Glasser carbon violin and I love the way they dressed up the peg ends by putting a slight dome on them.

@bocaholly - If you are interested in the Wittner or Planetary pegs, we'll hook you up.
Felix might protest but that is just tough..... LOL

@Fiddlerman Pierre, if you have a violin set up with the Wittner pegs, I'd like to give them a "spin" next time I'm in the shop.

I made a mistake on a previous post, which I have just edited.  The Glasser carbon violin comes with Knilling pegs.  The Wittner pegs offer finer adjustment, but I find them more difficult to install.  If you like to use synthetic strings (and who does not), an interesting (and inexpensive) compromise would be to use standard pegs on all strings except the e, and use a Wittner on the e string.  The 8:1 gear ratio on the Wittner really shines on the e string.

I'm a bit late on this thread but I know that you both tested the pegs and ordered some fancy ones. 🙂

It'll be exciting to install them on your Sima 🙂
