A violin bow was recently brought into the shop for some rehabilitation. Both holes for the screw and button, including the nipple, needed to be bushed and remade. The process is explained in detail here.
Bushing the Stick of a Violin Bow
Frog Bushing
Over time, the eyelet in the frog can become worn out and needs to be replaced. After several replacements the threads in the frog that the eyelet screws in to can become worn out as well. This Bausch violin bow has been well loved and well used over the years and needs a frog bushing.
