This is the bottom plate for a Thien-style dust separator project.
The link is to a Easel SVG import that I shared (hope I did it right). I need to carved out a dado 3/4" wide by 1/4" deep between to two light gray rings. I intend to use a 1/4" bit.
I cannot figure out how to set the depth for the area between the light gray rings.
Additionally, how to close the paths to cut inside and remove the ‘C’ shape with tabs instead of setting to carve the entire section?
