Dude! Your work is one of the best I think Ive EVER seen, and Im only on page 5 of the (long version). My dad (many yeas ago when he was still alive) was a luthier.
I dont aspire to be one... I dont have the patience, and have certain impediments, which will impair me... however... I do have two full toolboxes of some of his tools (I think) which may assist you moving forward ? Like the canned spray can thing ☹ I think I may have a gun or two for you ? As well as some other odds and ends which may come in handy, I dont know ? Either way, I reckon with this amount of passion, I reckon you deserve to have them. Let me know if youre keen... and Ill do my best to move the beasts out of their hiding spot in storage and try get them together for you. Obviously you will just have to collect them / or someone else. Courier services may be a B*TCH. Ill see if I can find them this week, and give you a shout?
ie. Consider a Badger airbrush for finishes... Theyre worth their weight in gold.
