So I got a set of 10 bone blanks from a place called Philadelphia Luthier Tools https://www.philadelphialuthiertools.com/ I asked if these blanks were the right size for a Stratocaster. Tells me yes but the Blanks are over sized. I check them with a caliper and they are around 0.180. I need them to be 0.125 So I get out sand paper, and piece of tile to sand on and start sanding. Man that would take all day even using 100 grit sand paper. Maybe I'm impatient? I do have a spindle sander that also has a belt sander attachment for it. This one right here. WEN 6523 Oscillating Belt & Spindle Sander http://a.co/62uIajk I couldn't think of a good way to do it holding it with my fingers so I had to stick the bone blank to a block of wood using double sided tape to give my self some room. before I knew it I sanded off to much and create a wedge shaped blank that was too thin at the back. I really don't want to have to go and buy yet another machine to do this right so I'm asking for help on how to do this with what I got Any ideas? If I could get the thickness right I'd be okay on everything else.
