Well, just curious about Stewmacs hotrod truss rods. I have six, so I guess I should be more curious about installing them than most people ;-)
So, with the brass "blocks" at either end being near as damnit 15mm deep, and the rods 14-15mm from the top of the rout in "relaxed" state (thanks to that PVC wrap), what depth should I curve the truss rod rout to? My instinct tells me 15mm for the brass blocks with a curve dip of about 17mm in the centre of the rod. Now, how much wood should be left between the rout and the outside world here? 4mm would seem "stable" enough but that leaves a neck depth of 21mm plus the depth of the fretboard - one fecking fat nuck!! *cough*
I suspect I've already screwed up one awesomely made (for a first neck) mahogany and purpleheart neck with a truss rod install which has insufficient recess curve, so advice would be gratefully received. BTW - what happens when you have NO recess curve for the truss rod? *cough* Sorry, I must be coming down with a "cold" or something.
Your respects to the (potentially) deceased party please:
FYI, that mark is sweat from hard consciencious work. Wooha!
