and not something I built “today”. I show a pic of raw wood modified to allow stock flipping to machine the curved outside and insides of the plates. Then I show some machine plates. The plate without the start of the F-holes is quarter sawn bigleaf maple and the lighter one with the holes is quarter sawn spruce. The lighter one is too thin, but I fixed that in next iteration that I have yet to machine. Quite happy with my Shapeoko. The plates are finished to 90%. I take it home manually as plate tuning must be done manually.
Hi Byrne. Using Fusion 360 which has its own proprietary format I believe.
No, I didn’t complete the F-holes because I don’t have a small and long enough bit to complete them. I need to resolve a machining issue I’m having which will allow me to use my small and short 3/64" straight bit. After speaking with my acoustic violin making guide, he told me that in the traditional method of making violins, he waits until he finishes the plate tuning bore cutting them. Consequently, they’re not cut in the next iteration of the front plate.
Hi Jim, if you’re referring to lining up the front and back plates over the mould’s block and rib assembly, CM drilled holes for alignment pins into the plates and there will be corresponding holes in the upper bout, lower bout and the four C-Bout corner blocks when the blocks have been machines after having been glued to the mould. That’s a work in progress, but it works great in my mind! I’ll start testing next week.
