CNC Project - Guitar Neck (and the rest if I can get away with it)

Hi Rob

Yes I have seen those guitars - they're really nice.

That Harpejji looks interesting and looks to be more 2D than a Fender design so should be doable if you can find a design/blueprint somewhere.

The Harpejji board should be simple on a CNC router, it is just a matter of getting the fret distances right. The formula is something like 1/17 of the remaining distance to the bridge (but I would check it out properly). Electronics are more of a problem, I think you will need a sustain circuit for each string and that, in turn, means individual pick-up coils. The Chapman Stick works on a similar principle.

Yes makes sense - there's a couple of scale length/fret calculators out there (Stewmac and Manchester Guitar Tech iirc have them).

I must look into Sustainers as well at some point - I'm guessing they are similar to my beloved e-bow?

I've always fancied having a go on a Chapman Stick and didn't realise they use a separate pickup coil per string. That's very similar to the Gittler, which is another concept I've had in mind to incorporate into a guitar design.....so many ideas...so little time :)

If you want to trigger MIDI you need separate coils like on the Shadow SH35. Roland do a similar pick-up, but I can't remember the model number. Otherwise I suppose you can get away with standard guitar pick-ups.

My experience of MIDI guitar was a little fraught, to say the least, and I have the Shadow kit sitting on a shelf doing nothing for a number of years.

Hi all,

Some CNC for the Jaguars whilst I wait for the lacquer to harden:

Part 15a - CAD/CAM



Part 15b - Machining:

Hi all,

Latest video in the Jaguar saga is up, but no CNC this time:



So by way of compensation here's another scratchplate machining video and CAD/CAM walkthrough from another guitar project I'm getting to the end of:
