Theo, that video was AMAZING! Thanks for sharing it! When I first clicked on it and saw the time (27:29) I thought I would watch it later, but I couldn't bear to stop watching. It seemed like it went-by in five minutes. That dude is a CRAFTSMAN in the truest sense of the word. I saw he is bringing-up his daughter as an apprentice and she appears quite skilled, as well.
I had been wondering (because of an upcoming project we have) how carbon-fiber could be utilized "hand-in-hand" with wooden construction. This guy is quite practical and I noticed that the two of them are extremely precise in their measurements and proportioning of the epoxy glues and sealants (using a gram scale). He used a well-thought-out mix of modern and old-fashioned tools, and especially made frequent use of a rasp!
At approx 20:00 his video quickly passed-by an interesting drill-guide for use with his hand-held drill. It appeared to be a simple block of wood with multiple strategic holes - possibly made with a forstner bit or two. I noticed he was using a folding rule for some of his measurements and precision calipers for others. I feel confident that he has built enough harps to know where approximate dimensions work - as well as where he needs precision dimensions. Anyone has got to admit that metric dimensions work best for things such as this! Regardless the number of strings his customer desires, this dude has some extremely well-honed skills.
Theo, I need you to help me to keep a SECRET: Joy is a collector of musical instruments and she can play all of the instruments that she owns. If she EVER SEES this video, she will want me to build her one of these, and I gotta tell you now: It would not come-out so nice, GUARANTEED!
Thanks again for sharing that video and THANKS EVEN MORE for keeping my SECRET!
