Hi Barbara-
I have a number of cranks and knobs scattered around here, some of
which I've made, and some I haven't. Most of them have a diameter,
at the widest point, of right around 1.5 inches, give or take a 16th
of an inch. The lengths, i.e. measurement between the crank and the
end of the knob, vary more, the shortest being 2 inches (old ivory
knob from a 19th century French instrument) and the longest being
about 2.5 inches (a modern European instrument). I make them 1.5
inches in diameter and about 2 and 1/8 inches long, but there is an
1/8 inch gap between the inner end of the knob and the crank.

Hi, all,
I need to order a new crank knob for my little ruin of a gurdy my
husband is working on. I have a source, but I need to specify a
size. The old knob is too small at about 1.25" or 3.3 cm in
diameter. I don't have any HGs around to compare and have limited
playing experience. I don't have dainty hands, but they are
lady-hands. Is another half-inch, or 1.2 cm, too much? It needs to
have some "neck" to it, how long should that be? What is the current
ergonomic wisdom?
Thank you for any help,
Barbara
