This is a very simple jig, it has a base and two fences. The bolts allow fine tuning of the centerline and also hold the neck blank in place. Watch the video to see all the details.
Based on comments, feedback and a few of my own ideas, I redesigned the jig. Three major updates are:
- the inner dimension, between the walls, is now 6″
- the bolts are held in place with t-nuts which makes it much easier to turn (see photo below)
- a nut is used on each bolt to lock it in place (see photo below)
T-nuts to hold the bolts on the truss rod channel routing jig. Once the position of the neck is set with the bolts, the nut can be tightened to prevent the bolt from turning.
