I’ve started doing some more precise projects and I’ve been focusing on dialing in my lowrider. I’ve got the xy square .04 diff on diagonals and .02 accuracy on x/y cuts on a 150mm square which far exceeds anything I could have dreamed of. My goal has always been .5mm accuracy.
My z on the other hand is ugly. I’ve never surfaced my spoil board and I’ve got hills and valleys up to 1.5mm in my bed, I tried making a box with half laps and I ended up all over the place on my doc +- 2mm.
I def need to surface my machine… my question is would it make sense to surface the plywood bed prior to installing the spoil board to provide a flat reference for the spoil board and reduce the amount of material removal for future spoil boards?
