This was the part I never understood. There was a finished CAD ready to go. Instead, it was printed out on paper and mounted to a board and modifications were made. No thought to how one gets those mods back into CAD to cut a real CNC playfield.
I’ll liken this to what I do in electronics. Long ago I breadboarded everything, with a rats nest of wires. These days I come up with the design, put it into EasyEDA, send it off to JLCPCB, even having them build most of it, and I have a testable board in a week.
The CAD should have been modified to John’s initial liking and then made via CNC. Way faster than whatever he is doing. Even if he had a flipping whitewood of sorts it would still have to get back into CAD and tested via CNC.
I know I know, I am asking for logic after 12 beers. But the thought process is so foreign to me it’s just baffling.
