Thanks. I have one more to make – for the key-hole blade that came with the assortment. Need to tweak the design for that.
The tool path for the outside of the handles, with the filets, was mysterious to me. Fusion 360 seemed to be responding to the isoparms (isocurves?) at the inflection points on the outsides of the model (the bottom of the assembled handle). On a couple of passes it reversed the feed direction there, then it retracted the tool, drove back into the stock a few millimeters away from the edge and resumed the cut. I am trying to figure out why it did that, and how to stop it.
