Today I installed the truss rod following LMI's instructions. The video will also show you what it looks like and how it works. I got the double acting one because of the tremendous amount of uncertainty in building my first guitar. It does no harm but costs a bit more.
I used a 1/4” router bit to mill a slot 1/16” deeper than the rod. Then I milled down a piece of hard maple to cap the slot as instructed with epoxy.
Before installing the truss rod I gave the bottom of the slot a thin bead of some leftover silicone caulk and I masked around the threads and installed the rod with the tape on it. LMI suggests doing these things. The caulk is prophylactic for vibration noise and the tape is obviously to prevent jamming the threads.
Since the fretboard blank arrived in the mail last night I can begin prepping that for binding tomorrow.
