I got this idea from one of Beau Hannam’s videos. It gives me much better results, much more easily than what I did before when trying to get necks straight and smooth during the carving process.
Make a block with a flat side (length determined by the instrument neck size) and glue sandpaper to the flat side. (I use PSA sticky paper so this is easy.)
This is used to sand the neck cross-wise which gets things really flat, and find all those little uneven places. I get a really good neck with little effort. The one thing I do which Beau does not is that I mark pencil lines all over the neck so I can see where the high spots are, and when sanding can give those high spots a little bit of extra sanding. Also the pencil lines make sure that I have hit everything.
just starting out
half done
only a couple of low spots left.
