Last week I refinished the neck of one of my jazz-type basses, a 5 string, since it had a VERY thick poly coat on it. I sanded off the finish and applied several coats of tung oil, and the neck was absolutely beautiful and perfect, UNTIL I tried to reinstall it on the bass. Stupid me, I should have left the neck-pocket area of the neck alone, now it seems that I have a 1.5mm gap all the way around the neck, pocket is now too large. New neck isn't an option, I was considering some sort of filler. Ideas thusfar are injecting some epoxy into the joint, wood filler, bondo . . . what would you suggest? Would it be best to insert the filler with the neck on, or should I build it up in the pocket first and re-route it to fit the neck perfectly? Thanks a bunch.
