I bought a student grade violin from the Goodwill for $50 and was going to experiment repairing a top crack, as I'm interested in learning how to do this as a hobby. I bought Behlen's hide glue over the internet, have watched Daniel Olsen's YouTube video on the topic, and have some spool clamps and deep throat clamps.
Can I buy the wood for patches at the hardware store for this level of restoration?
I called the shop where this violin was originally sold and they informed me that they use hot hide glue for gluing their violins, but the student grade varnish is possibly polyurethane. Will the polyurethane varnish make it harder to open the top? Can I sand it after repairing the crack?
When purchasing the violin, I didn't notice that the neck has been broken and reglued. Under the fingerboard it looks like there is damage to the top plate (possibly caused when someone tried to remove it before?) that has been fixed with some glue that looks kind of yellow. Will this make it impossibly hard to remove the top plate without further damage?
Your advice is appreciated.
