It's always a good idea to give the truss rod nut a turn so the rod is not placed in upside down by accident. It happens!
Squeezed the truss rod in and run a line of glue each side of the slot. Then the plug is coaxed in - by coaxed, I mean rammed because that bugger is tight - and that's a good thing.
And the clamps are tightened very tightly so any natural bow in rod's aluminium sleeve is flattened.
Now we need to address that big nasty router goof where the template slipped. First, the surface is hacked at with the world's rustiest razor blade so it's keyed in for the epoxy to bite. This stuff is pretty good at bonding to rough, porous things like wood, but it never hurts to over-engineer.
