I am currently rebuilding an old Russian harp that had his neck snapped without notice.
I am going to use beech ply wood for the new neck. Right now the question mark I have is the Tapered drill for the tuning pegs. I need to know which type of cone there is for the original pins but I don’t know how to measure the cone’s step and convert to the conventional sizes.
I would be most grate full if some one could tell me how to do the measure or just point me out to the right size of tapered pin reamer.
