Let's drag this up - I've not posted an update for a while. As you may be aware this is my "back burner" project. Anyway having finished getting the ebony headstock cap down to thickness, last night I had a go at routing the truss rod channel. I borrowed a jig from a "class mate" - it leaves a bit to be desired in terms of stability & clamping options, but with some suitable packing was fairly useable
Fixed to the top runners are two curved fillets to give the bend for my old-school conventional truss rod. Unfortunately the instructor that made those pieces for me while I was aligning and clamping the neck in the jig didn't quite put enough curve in them, meaning I only have a 1.5mm drop rather than the 3mm I need. Anyway, using a 6mm half round bit I at least have a tidy curve to the correct depth at either end.
I'll now use a 6mm chisel that has been rounded over at the tip, to scrape the centre of the channel to the correct depth. I'll have to get that done this week as I've borrowed it from the class and need to return it. The classes have now finished until September, but one of the instructors lives not far from me. Needless to say, progress on this guitar will slow even more while I get the Nozcaster finished off (which I just noticed has photo-bombed that last picture! ).
