The Tele files I bought from a guy in Spain so I can’t really share them, sorry. They are also in Vectric Aspire format. In any case, yes, I did the back carving too and it came out very nice, very little finish sanding. For the fret slots, I did not have the correct Stewie Mac 0.023" bit when I did this test, but tried it on a later Maple neck and it came out great. The only problem with milling fret slots is it is extremely slow. I mean really, really slow as the bit is so fragile. I’m going to make a CNC machine to automate the fret slotting using a 2-axis setup with a 0.021" slitting saw with a Arduino controller running grbl. I can program that to do any neck scale and accomodate anything from a mandolin to a bass neck. I prototyped it on the Shapeoko and it works great.
