Still working on the drag knife, still having issues… not sure what the exact problem is. I am starting to think that the length might be an issue as my z axis has a bit of flex due to the unsupported wood the router mounts on, it is minor but 5 inches lower it is magnified quite a bit. I modeled this as close as I could to the Donek 1/4" knife, the blade is centered to the rotation, with the blade tip offset ~.16", using VCarve Pro drag knife gadget to generate the path… I am starting to think a tangential knife might be easier.

My initial reaction was that your blade angle is too steep or your blade isn’t sharp. It’s catching, not cutting.

Hmmm… blade is new, not sure what to do with the angle, it it modeled after other drag knives… will give it some thought… thanks.

It could be that the weight is pushing it too hard into the material. Corrugated wouldn’t be my choice to cut. Have you got some packaging card, like a cereal box?
