We decided to change the cross-sectional shape of the wood pin from the initial plan.

I am currently learning from an old cello, which I am using as a reference for my cello making.

“Old Italian Cello” 1700年頃 (  F. 734-348-230-432 /  B. 735-349-225-430 / stop 403 / ff 100-167-231 )

It is important that the cross section of a wood pin is an irregular shape close to a hexagon, rather than round or square.
