This originally got started in the "Gibson SG ukulele build" thread, but I'm moving to this new thread as it develops. Building ukuleles is turning out to be pretty fun. Next up, a version of the "AstroCaster" guitar I designed & built: Today I routed & glued the carbon fiber rod in the neck blank, and made a jig to cut my very first fretboard slots. Turns out to be pretty easy using cheap materials that I had on hand- a Harbor Freight Japanese pull saw, a carpenters square, some left over wood chunks and some carpet tape. I used a piece of 1/4" MDF taped to the saw blade to stiffen it & set the depth of cut. The same setup could be used on a full size guitar as well.
