I am having a devil of a time using the devil's can-opener.
I am trying to cut v grooves on chair legs. Once they get deeper than 1mm, my point catches the edge and skates down the leg. I have watched a bunch of videos and thought I understood the physics of this cut. But I cannot for the life of me tame this cut.
Below are my practice cuts.
It feels like I am catching the top corner, where the notch begins. The only way I can mitigate this is to approach the notch with my tool 90 degrees to the work. This has the effect of making the notch more vertically shouldered instead of my desired 45 degrees.
How do YOU do it? Any references welcome. I have already watched the Batty and Lacer videos online.
