Red Special Guitar Body (Lower Section)

Please see attached video and pictures of milling a test cut Red Special guitar body lower section from custom made blockboard using a 2.5 D toolpath generated in MeshCAM.

There are three non-contiguous parts which I had to join together because the Canon Powershot G15 compact zoom camera is limited to 4 GB videos at a time as many are. The total toolpath time was 1 hour 44 minutes. I think this is plenty to give you a flavour of how it all works. ;) Basically there's about an hour of roughing passes. I think that's pretty much all you see here so it's a bit repetitive.
