The truss rod slot

For me, building guitars is a great learning process, challenging, frustrating and satisfying in almost equal measure.

Yesterday was particularly satisfying ... there's something inexplicably pleasing about cutting a nice neat channel in a piece of wood.

Three necks, ready for truss rod insertions. From the left, that's mahogany, maple and a walnut/maple/walnut laminate.
See a perfect fit ...

Just need to get some silicone sealant to run inside the channel to stop any vibration/rattle, though I don't think that there's actually enough room in the slot for the truss rod to vibrate!
Almost seems a shame to cover that truss rod slot with a fretboard, but I think it might help playability if I do add the fretboard.
