Since it 'on my list' to someday make a clock, this interests me.
Would it be acceptable to do a simple scale factor, keeping everything in the same proportion? If so, I could generate the geometry in a CAD program, then the wizard would simply scale the job based on the outside diameter of the wheel. If I let the user specify the individual widths and arc radii then it gets a lot more complicated.
Would 3, 4, 5, and 6 spokes be enough?
I assume the wizard should allow for a rough pass and a finish pass, select a cutter diameter, and set total depth of cut and steps depth.
I can do this, if there is interest. Show of hands please, for those interested?
