Indeed. And thank you for your response. I appreciate your ‘first build” skepticism and will take it as a complement. Life long woodworker and 4 year hobbyist CNC’r with desire for perfection (rarely achieved) result in a lot of chips and kindling haha. I went through 19 design iterations to come up with the final one, posted above. I am not an artist like so many here, don’t even do stick men well, so I’m thankful for CAD, despite the painful learning curve.
Re truss rod, I have a “u-channel” from StewMac, 0.4” wide, so I guess wider then most.
As for pots, I ended up ordering a couple of 500k and a couple of 250k. Pretty easy to swap around so, why not? Also, as you mentioned, a 3 way slider.
A question about fret wire, is any particular size more suited to a beginner? Also, fret board thickness? I’m going with a radiused design, ~ 1/4” thick at center. Is thickness critical?
