So like, I'm building this guitar for a friend of mine.. And this is the method I use to glue the fretboard.. Here are the pics: I wrap a lot of inner tubes of a bicycle (under a high tension) around the neck.. Maybe it looks stupid but it shure works.. I learned this method from the luthier who teaches me.. I was wondering who else uses this method.. I know it's a guitar but I build my bass guitar necks like this.. Any comments?
