I recieved some feedback about the layout and spacing of the keybox vis-a-vis the wheel, and realized one more iteration would have a positive effect. I built a third keybox, and incorporated the criticisms; I also lengthened the outboard extent of the keybox so I could dress it up a little. Instruments that look good sound better. I don’t know why, but it is so.
This week, time permitting, I will try to mount the wheel. Once that is done, I can figure out the top layout and bracing design.
