Re: crack repair

1. Fill the crack with super penetrating super glue. Do not fill all the way to the surface of the wood. Let dry. (If crack goes all the way through, I use a gel super glue to keep it from flowing inside the instrument.)
2. Mix up instrument grade epoxy (Ferree's is a good source) using some of the black coloring. Mix in ground up grenadilla dust.
3. Fill remainder of crack to surface. Let harden overnight.
4. Sanding very lightly, remove any epoxy on the wood beyond the crack. Smooth the epoxy until it is even with the surface. Don't sand too hard or chunks might come off ruining the even appearance of your repair.
5. Use fine steel wool as last abrasive.
6. Apply a bit of bore oil to the wood where sanded.

Crack should be nearly invisible.
