Awesome work, and thanks for sharing! I've messed around with modeling the carve top using NX, but I don't have the CAM license for NX, so once I eventually build a CNC I will have to lean Fusion so this will be very helpful!

I would also assume that he is talkin about a thickness sander, but I concur that a thickness sander is really not needed for guitar building. It would be nice to have one, but it's certainly not necessary. A spindle sander on the other hand is pretty much a necessity IMO.
I've also got the little porter cable jointer and it has worked well for me. I recently picked up the 8" cutech benchtop jointer with the spiral cutterhead, so I will be saying good bye to the porter cable.
