I'm cutting the 6th fret... all are cut to the depth of 3/32" with a simple guide block clamped on the left of saw. It gets a little harder to saw through on the last 1/32", so the parrafin (white) helps lubricate the saw a bit.
After all the 19 frets are cut, the fingerboard is tapered from nut width of 50cm to 12th fret width of 61cm. With the lines drafted, the fingerboard will be carefully planed to them.
Here's work done so far...
