It took about 10 hours to cut these. I cut them together until the end when I decided that I wasn't capable of making the small details on the boat. I think the thickness and the detail necessary was the problem. Thin blades were difficult with the thickness of the wood, thicker blades did not allow me the detail. Once separated it was easier, mostly because I wasn't worried about the blade diverting and ruining the other piece. I love cutting Walnut, and cutting a single layer of 1/8" BB is very difficult to control the blade. I generally cut at least two of anything when cutting 1/8" BB just because it's easier.
I have a Hegner :eusa_danc. I would not have tried this on my Delta, though it probably was possible.
