Guitar Building with my JazzCNC machine

Dean, you should throw in a packet of HobNobs after such a great advert

Cheapskate!.
More like a bottle of single malt (or 2)

I think Ben would appreciate a lump of Brazillian mahogany more, which I do happen to have. Would cost more than the machine to post though..

So since my last post, I have managed to cut the neck and pickup cavities for the guitar. These are perpendicular to the plane of the neck which is 4.2 degrees in relation to the back of the guitar. I built a simple jig which is angled at 4.2 degrees and fixed the guitar to it, this way, the machine is doing simple 2.5 cutting. If I were to cut it with the guiar flat to the CNC bed it would end up a mess as the cavities are essentially undercut.....



Next up to create a neck. I dont have a lot of photos of this, but essentially I cut the cheeks of the tenon joint which are again 4.2 degrees using the CNC and a 4.2 degree wedge that allowed me to simply cut a straight vertical line for the cheek of each side of the tenon and then just drove the CNC around and machined the waste wood away. I then created my G code for the neck and machined just the shaft of the neck and the transition into the headstock using a combination of adaptive, parallel and "steep and shallow" operations in Fusion....



Came out really really well , the more I use this machine the more I love it !!





Its really starting to look like a guitar now !!



I need to glue two "wings" onto the headstock to make up the full width and then cut the final headstock shape which I will do on a normal router table for speed and convenience. Once that is done I will glue the fretboard onto the neck, blend in the stock that I left proud on the edges of the neck and then we are onto the home stretch !!
