Guitar neck truss rod and reinforcement




A low tech, but good way to route a channel into the neck.  Two identical tables with one edge flush with some oak pallet blocks.  the neck is bound between the tables using bar clamps.  A guide on each side of the router keeps it in the channel with no chance of the bit wandering.

The second photo shows the heel of the guitar neck.  A spline is glued in to help keep the heel stack from separating.  Also note that the grain of the blocks in the heel are alternated so the grain is not in the same direction.

The third photo shows the taper of the guitar body, which, in my opinion, gives the instrument more presence when it's played.

In the last photo, you can see the taper of the neck.  The bump at the back of the head of the neck is going to be carved in a diamond shaped taper, which is a feature of some old Martin guitars.
