Neat stuff.
Please keep it coming.
When I first got this teaching gig, back in the 70s, I found a 16mm film of some "educational" Saturday morning kids' TV show...there was segment of a tour of the Fender factory...showing how a bass was built. I don't remember much of it, but I remember how the frets were slid in from the side...AND how the shape of the neck was cut in two passes, one for each side, by a big honking shaper bit. IIRC there was a metal template fixed to the front of the neck, and the bit followed the pattern. Like a pin router I guess.
I showed that to the kids every year...until it just up and disappeared from the library I got it from...low circulation I guess.
One of those big honkin' shaper bits would make your upcoming days a lot easier.
