So making a radius is not easy for the... tool challenged. That is, if you don't have the right tools and we all don't at one time or another. So I devised a clever tool to sand down a fretboard to the radius I wanted.
I picked this idea up from watching some luthiers sand down the fretboards on a Youtube video. They had a long block with an interior radius and sand paper in and ran the fretboard over it. Ok, I don't have that tool, but I do have a sanding block. Well, a length of 1x2 poplar.
I thought about it and then came up with and idea that uses tape layered in a fashion so that there was more tape on the ends than in the middle. The block is flat but the tape creates the 'radius' Since the sandpaper smooths out the ridges, the final fretboard looks REALLY great (pic to come).
Hey Guys, please forgive my ignorance but Im not getting the concept. If there is tape on the edges of the block with sandpaper in the middle how does the sanding block not make a U-shape on the neck?...looks like you are getting the opposite desired effect, Im just not following. I realize Im overlooking something obvious...thanks!
