The way the neck jig works is not to put relief in the neck. It’s to simulate the neck under string tension. This is mostly for refretting older guitars. After a while the fretboard often takes on some humps and dips. But they often only show up under string tension. So the idea is you get the guitar in the jig strung up to tension, and turned on its side in playing position. Adjust the truss rod so the neck is straight with no relief. Then you adjust the fingers up to the back of the neck and then remove the string tension. This keeps the neck as it was under tension. Now you can true up the fretboard. Or just dress the frets level.
Like I said in this video, I didn't use the jig like the Stewmac version. In my opinion, the stewmac tool is not necessary for great fret work with a new or used neck.This is something I tried years ago when I carved the back contour first. I used it to keep my necks straight when running straight edges and sanding blocks across the frets. This way the neck wouldn't sway down in the middle having the rods underneath. Now I do fret work before the back is contoured. I have a video coming out soon showing how I do this now. Please come back to check out these future videos. Thanks for watching!
@@lesperanceguitars8381 It’s unnecessary for a new neck with new fretwork. It’s very handy for re-fretting a neck with problems. I never use one for new builds.
Great set of videos. Explained in an easy to understand and very informative way. Exactly what I was looking for. Thanks! Also in the Intro video what and where did you get that awesome router bit that you are routing the body of the guitar with. I need that!
Thank you for the nice comments and I appreciate you watching the series. The router bit is a Mega Flush Trim bit and it comes from Infinity Tools www.infinitytools.com. This bit comes in different sizes. I have the largest size. It is a monster. It will do quick work on the bodies in one pass. I use a DeWalt DW616 1-3/4 HP router and have to slow the speed down a little to match up the recommended RPM. It's pretty intimidating but you just have to keep the piece moving. It's a little pricey too but I think it is worth it. Once again, thanks for watching!
