Things get quite involved over the next few steps so pay attention. In this step I'll show you how I install the truss rod. You will be using your router with the straight cut bit again, a good quality painters tape and epoxy. Also, you will have already partially completed your fret board, so you need to kind of move from this step to the next and back again. The truss rod itself was made following another web site (http://www.veddermountainhardwoods.com/2009/03/30/how-to-make-a-guitar-truss-rod-video/) so I won't repeat that process. You could also buy a ready made one if you want to, they are not very expensive.
