Doing Things Wrong

Superfreaky Part IIa

I finished the shaping with a big metal file and 80-grit. Then finish-sanded 100-150 and cleaned out the fret slots. 150 is good enough for now. For final finishing, I'll take it up to 320, which is smooth but leaves plenty of 'tooth' for the finish to grab onto. I wouldn't go any higher - the surface becomes too smooth.

Finally I put several coats of poly wet-on-wet on the fretboard, to build up a single thick layer of plastic. That will give a nice thick protective covering over the stained surface. That will need a few days to harden-off, then I can smooth it down, install the frets, and give it a thin top-coat, and also finish the rest.

Fretboard Radius Blocks

I make all my fretboards 12 inches, guitar or bass, fretted or fretless. I just like that, and also, it doesn't matter that much as long as you stay away from the extremes. 12-inches is a nice comfortable curve for chording on, and also doesn't require as much work and mess to carve as a smaller radius. I find it is a good compromise overall. I can make a 12-inch radius from flat pretty successfully with just a sanding block. StewMac's pre-radiused boards are 16-inches and are quick and easy to re-radius to 12. Although I made tooling for everything from 7 to 16, I don't use any of it. Luckily, I made extra tooling for 12 inches before I broke down the manufacturing plant.
