Hi guys, looking for a bit of advice here. I'm building a parts caster mainly using odd bits I have lying around, so I'm not looking to buy new parts. However, the neck that I have is slightly too big for the body that I have. The neck pocket measures 55.6mm (2.19") and the heel of the neck is 56.5mm (2.22"). So it is slightly too big. My question is this: am I better of sanding the neck heel or the neck pocket in order to make it fit? And will this badly affect the allignment? Thanks!
