I can remember those disks by Kavan. I think at the time though, most of my needs pretty well dictated a need for 90 degree or 180 degree holes. There was a poop sheet that went along with them to let the builder know how to calculate tne position for drilling the holes.

So who then wants to mark and drill for special holes?

I sort of wish they can ready for currently available servos, but there is such a variety of mountings available now. Square shaft, splined, and just how many splines too.
