Now that the decoy is basically carved to its final shape, I'll start the hollowing process. I'll do just a bit more carving to refine some details, but I'm now confident that they will be minor so I'm ready to hollow. 

Since I never did glue the two halves together, all I have to do is remove the screws and the decoy comes apart. The bottom is the easy part to hollow. I chuck a forstner bit into the drill press and set the stop so that it doesn't drill any lower than about 3/8" inch. I'll drill out as much as I can.
