Ok, so I bought a bass on CL for $50. It's a P-bass knock off. The action was pretty high, when I got it home I found that the truss rod nut was stripped. I had a friend machine another nut for me. Even after adjusting the action is still way high, so I've got a warped neck. I've thought about it, and I'd like to try and repair (straighten) the neck. I have access to an environmental oven ( basically I can control the heat and humidity). Here comes the onslaught of question I've for you guys. 1. How do I clamp this thing up? I know I need a straight edge to clamp along the fret board, should I remove the frets or can I do it with them in? 2. Should I remove all tension on the truss rod? 3. At what temperature should I set this at and for how long? 4. Should I use humidity? If so what level? If I'm correct with my research the wood will move more with higher humidity. What I was thinking was to run it at about 75% humidity 160 F for 12 to 18 hours then reduce the humidity, same temp for about 6 hours, Then take it out of the "oven" and let it sit at ambient temp and humidity for 48 hours, then unclamp. I'm only in this thing for $50, so if I screw it up it's not a big deal. Any experienced suggestions are much welcomed.
