i dont really have a way to get the t rod channel straight, so the only thing i can do is make a fence with a big piece of wood, but it is really inaccurate. its not exactly the scarf joint itself, its how you cut a 2" neck to profile width and how you cut behind the scarf joing to keep it at an angle. also after the fretboard is glued on, to reach the truss rod nut. do you have to rout it deeper under the nut? because i diddnt think of that and now the t rod tool doesnt fit under the wood to fit on the nut. TOTAL CHAOS! i know its my fault for not thinking of everything, but after months of planning i diddnt see anything left to plan. i guess im not fit for this stuff. i think i will stick to making bodies. those come out great. i knew i shouldnt have tried it again. wasted a good 30"x3" piece of mahogany. dang. i hope i learn eventurall
