Hi Prostheta,
Basically, after the routing was done for the T-Trem, H/H & neck pocket, I fine tuned the outline shape to where it needed to be. From there I used a 1.5" roundover bit/ with 1/2" shank. This felt like the router could have taken me on a flight, so I made very shallow passes with the router until it the bearing was flush against the side of the body. This left the body with very rough shaped corners. I then hand filed & sanded the rest to even everything up until Trynyty gave the go to stop. The end result is an even radii with no body/belly contours needed. From there I filed and sanded the neck/heel extension & contouring. I would do it the same way again, basically you use the roundover bit to get the bulk of the wood out of the way & then it is carving/shaping from there.
I hope this answered your question,
Rick
