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
