Meanwhile I'm making stringholders for the cover plates.
I chose a piece of mahogany (or possibly that other wood, sapele) and ripped a long piece on the small table saw. This will be enough for all six of them.
The rabbet for the knots and the slope at the front edge were also made on the saw and cleaned up with small planes. The wood has a quite lively grain but planes nicely, getting a very smooth and hard surface.
Not much left now. No deliveries before christmas but early next year.
