constructing the NST Acoustic neck..
the timbers for the neck are prepared.. Bubinga in the center and Goncalo Alves on each outer edge
the G A is split down the center
and the bubinga is cut at an angle.. why have a straight bit of wood when you can have one that follows the lines of the neck..
each piece of neck is run through the planer and then planed by hand to give a perfect joint..
everything ready including the flamed maple veneers
and it's glued..
once dry the excess is trimmed off on the bandsaw
and then the whole thing is run over the planer to true up the edges
a vision of the future.. the very near future..
pretty..
the truss rod cavity is routed out
and then the fun begins.. making jigs and templates can be fun.. or infuriating.. still a good jig makes for a much more unifirm job in the end.
first off I rout around the edges with a standard flat bit to save digging in with the mitre bit
and end up with this..
bandsaw the excess off
and rout the joint in the body
a good place to be.. though the neck is a bit fat at this point
next up she is roughed to shape on the bandsaw
on all axis
and then planed to the finished size
the headstock face is flattened off
and the rough carving begins.. a long dusty process..
but we end up with something akin to a guitar neck..
the bobbin sander is used to get the correct curve at this end
and we end the day by glueing pieces of Bubinga and Padauk on to the headstock to achieve the desired width.. much prettier than your standard fare?
after cutting the excess timber off the tuner positions are marked out and double-checked.. if I'm going to go to the trouble of designing a headstock with straight string pull I can't let myself mess up at the last stage.. as my old master said .. 'measure, measure... cut'.. the only good thing he ever taught me!!
rough cut on the bandsaw
and then finely profiled using the bobbin sander
the neck is partially carved..
and then the final shape is rasped etc.. though doing this without a fingerboard on does cause some headscratching
but we end up with something which should be incredibly comfortable..
neck joint is tested out to see how the carve will affect the shape of the back..
and then the straightness of the neck is checked using the ruler down the center-line.
while the neck is clamped and glued I start work on the fingerboard.. carefully marked out
cut on the bandsaw and then fine planed by hand to size
measure measure cut.... ..
the fingerboard radius is planed.. in this case a slightly concave but still flattish curve.. for comfort..
next up this lovely little tool, made by a good friend of mine, is used to mark out the purfling
a sharp knife is used to make the scores deeper and then they are recessed using a very small chisel
the inlays are glued in..
and after sanding they are looking pretty good
the fret slots are marked and cut
and each fret glued in place.. makes for a much more stable neck in the end.. it's the smallest things that seem to make the biggest difference in this craft
the fret ends are then snipped off and filed off at a comfortable angle to the fingerboard and then finished with 400 grit garnet paper
the side dots are then glued in place.. not an easy job after the fingerboard is in place..
the dual-action truss rod is masked off so that the glue will not foul the action
and then everything is glued.. | |
