How to accuratly plot bolt circle radius?
In reverse engineering my radar scanner for mods, I am in the process of
machining an adapter, and I have run into a conundrum. I need to very accurately plot a bolt circle radius consisting of 4 evenly spaced 3mm screws, about 1/2" radius. The screws rock slightly in the threads, so I can't just mike the screw shafts and extrapolate.There is an open center, so I can't easily locate x0y0. The hole centers must be plotted very accurately for alignment of the vaveguide. Help?
