Steve, I didn't set the Max cut depth. I should have. The large diameter (3/4") bit digging in so deep is exactly what caused the slip. Tomorrow evening, if I get some time, I might give that one another try.
I'm certain the spiral Hollow will carve using raster carve. I want to try that too... That is what the jig was designed to do. But I agree that if it would do the vector carves, that would be another "tool in the box" so to speak. I see no reason why it wouldn't, if I had changed the Max depth like you suggest.

Thanks...

Ed

The weather is cooling off,, so I guess if some more firewood is in order, It might as well be pretty firewood.
