Luthier CNC

[bluesking]

Made a few minor updates based on the useful comments to date:

Upped the side plates from 15mm to 20mm (I've changed my mind about using reinforcement ribs here - seems like these might increase the risk of snagging on something or someone whilst the CNC is doing its thing)

Changed the front and back from extrusions to solid 20mm plates. Added 3 foot-like features to these so the base of the machine is basically a tripod to prevent it wobbling on the workbench.



Added some heavy duty steel brackets to the centre of the bed - I can't afford the cost or weight of a solid aluminium bed so this is my compromise. It'll all be connected to an MDF sheet lying on top of the bed structure with a 2nd MDF sheet on top of that as a spoil board.



Most everything else will be achieved using long screws into the extrusion cores, attaching them to the various plates.

Won't be able to machine my big plates on any CNC I can get access to but I am hoping to get access to a Bridgeport mill so I can at least drill all of the holes in precise locations (assuming I can figure out how to use a Bridgeport!)
