Crack in the soundboard, by the sound hole
Instruments- discuss specific features, luthiers, instrument problems & questions
By the way, at the upcoming Pocono Club Dulcimer Festival in Stroudsburg, PA (April 27, 27) I will be teaching a workshop for builders and repairers on how to fix cracks anywhere inside musical instruments, including aligning the two sides of the crackand cleaning the inside surface across the crack in preparation for glueing an interior reinforcing cross cleat.
All this is done from outside the inside the instrument! I pass all interior materials though the nearest soundhole, and clamp the crack with interior/exterior matching magnets, and clamp the cleat with a system of springs and stops. The workshop title is "Laparoscopic Crack Repair."I will be repairing a crack on an old dulcimer that was such a failure that I cut it in half to use for this sort of demonstration.
Attached is a photo of the interior cleat glued and clamped across the crack inside —all arranged with a thread passed through a small hole drilled into the crack and later repaired.
This workshop isn't on the website's schedule yet, as Norm Williams and I just talked about it last week. Builders, please spread the word!
