What do you reckon the Baja neck will fetch price wise, bearing in mind all its hardware has been taken out?

 

Honestly. Maybe $100-150 if it’s pristine with no dents dings scratches or fret-wear. Just a guess without any research at all

 

What grit sandpaper did you say to use for the peg holes?

 

First off. Tape the face and back of the headstock surrounding the peg holes. Preferably with painters tape - or a light tack masking tape. This will prevent you from scratching up your finish on the face and back of the headstock.

With some double sided tape or Elmers glue, attach the sandpaper around a spare dowel rod or something like a writing pen. Or you could also buy adhesive sandpaper instead of using tape or glue.

I’d use 250 grit & then smooth it out with 350 or 400 sandpaper.

Don’t go very aggressive, check your progress often & make sure to hit the inside of the holes evenly.
