I'm making a solid guitar body for another luthier that will have a radius on both the top and back along with (an expensive, chippy) 0.125" veneer glued to each. The back will have a different curvature and is tapered so that the bass side is much thinner than the treble side. This makes for some challenges in material holding and re-registration. I also have to mimic a compression bit by changing tools in the middle of the cutout tool path to get clean edges.
I did a test cut yesterday that involved all the steps I will take on the real project, but I instead cut out a hockey puck with a silly guitar shape:
It's involved, but workable - I can't think of a way to eliminate any steps here or register/hold it in a better way. Can you?

I did a test cut yesterday that involved all the steps I will take on the real project, but I instead cut out a hockey puck with a silly guitar shape:
- 8' radius the back
leaving four cylindrical feet at the corners with 1/8" registration pins - 12' radius the top
leaving four cylindrical feet at the corners with 1/8" registration pins - cut wiring channels and control pocket
- glue up veneers one at a time
- make a cradle for the back out of MDF - probably best to make it support the back periphery edge all the way around
- glue the cradle to the back veneer, run through the thickness sander to get down to level
- re-register and cut the pickups, neck pocket, control pocket
(I skipped this step) - cut periphery in two stages - down-spiral to half depth, then switch to a up-spiral bit for the remaining cutout
It's involved, but workable - I can't think of a way to eliminate any steps here or register/hold it in a better way. Can you?
