I'm after doing a bit of a test-assembly to make sure that things are lining up right. The neck when screwed in is sitting slightly lower (maybe a mill?) than the veneer. I was going to try sand until they met but, I'm guessing that might be a bad idea??
Also, just to check my logic is right. I've only put one string on, just to check everything seems to be sitting right. I'm getting buzz on the first 5 frets and I'm noticing that the neck is ever-so-slightly curved back at that point (truss rod too tight). I'm guessing that that might correct itself once there's 5 more strings on, and neck is under full tension??
