Stage 5) Building the truss rod

Use 10-32 threaded rod cut to length. Use a tap and die set to clean up the threads that will be used with the adjustment nut. Be careful not to cross thread the 10-32 threading. Next we need to make the anchor slug. Make sure it is thick enough to have enough thread engagement. Find the center of the slug and use a center punch to indent the center point. We are going to drill a through hole that will allow us to cut 10-32 threads into the slug. Then we screw the 10-32 threaded rod into the end of the slug. The eBook following this blog will have more detail on making the truss rod. I use plastic straws that are cut to length to keep the glue from getting to the treading. Using 2 straws for this process works out perfect. Tape the straw joint with Scotch Magic Tape to keep the wall of the plastic straw as thin as possible. Vaseline the threads for the adjustment nut and the bearing face of the nut to eliminate unnecessary friction when adjusting the truss-rod nut.
