I've hear of people grinding shellac flakes in a coffee grinder prior to mixing in the solvent.
My questions are:
PS: I know I could have posted this in Project Finishing - I didn't want to miss out on any smart / funny remarks!
- Is there a problem if you "overgrind" them to espresso grade?
- Does it do any damage to the grinder?
- Should it be dedicated to only shellac flakes thereafter?
