Here is my first neck build attempt. I bought 1" X 4" X 6' poplar from HD: https://www.homedepot.ca/en/home/p.poplar-d4s-1x4x6-feet.1000172689.html In reality the poplar is a tiny bit over 3/4" or about 19mm and that's what I needed according to the Crimson Guitars guy videos. I started with poplar because it's much cheaper than maple and my first few attempts will surely go to waste . Here are the 2 necks after a quick jigsaw cut. After that I used my plunge router to cut following the neck template, and finished the headstock with my spindle sander: I've had several tear outs on the long straight lines, and probably this is due to the fact that the router bit I used had long cutting length. How do I avoid tear outs when routing, do I just do it in very shallow passes with a short router bit? Was what I have done so far a good approach, or should I have done things differently? Next I need to route the truss rod channel. I have a new router table that I'm yet to assemble, however now that I think about it I don't have a straight edge reference on either sides of the neck anymore, so I can't use the router table fence as a reference . My neck template has a truss rod channel cutout - is there a way to use that somehow with the router to cut the channel properly? How do I cut the truss rod channel after the neck sides have been cut to shape?
