Hi Arle, Alden and Matt,
Thanks a lot for explanations, illustrations and questions. I'll figure out
howmany left and righthanded pegs I need, and contact Brian.
Greetings from Holland, Cor

Subject: Re: [HG] images of new pegs
Hi Matt,
The mounting threads do in fact differ for each kind of peg and I think
that's the important difference. The cores differ as well, however: the
teeth on the core do not run vertically on the shaft, but instead at a
slight angle and the left- and right-handed seem to be mirror images
(which makes sense). I think that by using the proper one, there is a
tendency for the natural pull of the peg when under tension to keep the
head pulled down as a result rather than tending to force it up a little.
But I think it is so slight a difference that it wouldn't matter under
normal string tension. So I believe that the operative difference is the
threading and since I've glued them in, as you note, it doesn't really
seem to matter much. I certainly haven't (yet) noticed any problems from
having put them in backwards, and as Alden noted, their supplier tells
them to do them "backwards."
Best,
-Arle

Perhaps this is a question for Brian, but maybe some other list members
would be interested, so I'll start here.
Why are these pegs left- and right- handed? From what I understand
about the way these planetary gearing systems work, I would think that,
like banjo tuners, they would work the same regardless of which side of
the peg the string wound on. Is there something about the construction
which makes these only work in one rotational direction?
Perhaps it's the *mounting* threads which are different? The tensioning
motion of the left-handed peg (our tourne-a-gauche) would naturally have
a tendency to unscrew the threaded housing unless the threads were
"reversed". But if they're glued in...
