My 50s reissue P sounds and feels great. I currently have it setup with a relief which looks around 0.13/0.14 at 7th fret - checking with automotive gauges - and an action around 2.5mm at the 17th fret for the E string. Quite in line with Fender's setup guidelines (the neck has a rounded 7.25" radius) and to me ATM feels just right with standard tuning and my Elixir Nanoweb strings. The neck is what you find in 50s P reissues: an old-school large chunky maple neck with a single-action truss rod accessible at the heel. I have managed to get this relief and setup which seems to be stable with the truss rod "fairly" tight - I would not turn it clockwise any further at all, it would seriously force and potentially risk being damaged. As I mentioned, the neck seems to stay fairly stable throughout seasons - if there are minor movements it's not something that's that perceivable or impacting my playing at all. My main question is: would you just leave it like that by serendipity or would you rather bother going through the process of gaining some truss-rod action by straightening it on a plank with back-bow and the truss rod loosened? I'm mainly referring to the method used in the great Dan Erlewine video on YouTube about straightening a similarly made neck: I previously applied some vaseline/petrol oil on the nut as well, so I guess the nut screw is not stuck. For all pro or experienced luthiers here: with a rather healthy neck like mine (I guess), how long would you leave the neck under tension on the plank? I can't get from the video if the editing cut a lengthier process or if Dan left the neck under tension just for a few minutes, while reinserting and gradually tightening the rod nut. I read around that some people leave the neck on the plank for days, I guess for seriously bowed necks. How much pressure/back-bow would suggest to apply in case?
