[LUTE] Re: Alcohol as glue breaker.
I for one see myself as a amateur lutemaker but I use animal glue throughout. Cheers!

[LUTE] Re: Alcohol as glue breaker.
Alcohol will only damage the varnish if a spirit varnish has been used: oil based varnishes (as used by most professional makers) are untouched. Alcohol quickly evaporates so there is no significant residue to block further gluing.
