Then it's out with the sandpaper. For this I use 80 grit because you need something that cuts reasonably quickly or I loose patience.
The piece used is about a foot long. It's used exactly like a shoe-shine cloth with one difference - not only use a side to side pulling action like shining the toe of a shoe, but at the same time pull it up and down the length of the neck. This way you take off the grinder irregularities without creating "bumps".
Note the
no touchy! area. Cut though this and your fretboard is no longer straight. That's what those pencil marks are for.
The neck is turned and clamped and after about 5 minutes of shoe-shinin' it's looking pretty close.
This still needs another run over with the 80 grit, but I like to walk away from it and come back the next day. You see things that you didn't see yesterday that need attention and you aren't bored with it, so you spend more time.
Then it's 120 grit and finish with 180 and 240 before grain filler.
I still have to grind this "heel" area comfortable and probably do the Tadeo curve on the headstock.
Cheers.
