This morning I pulled out the spokeshave and got at the rosewood fingerboard. I have noticed that cellos, violins, bass viols, all have radiused fingerboards. Seemed like it would make this two string creature easier to play-so radius it is.
The basic radius has been cut in with the spokeshave. Now to smooth it up with this radius sanding block
Then to the finer grits, First 120, then 180,220, 320 and 400
Finally the 600 grit. and this fingerboard is slick as a babies bottom
