Not Everyone Uses CNC

I am building a part that replaces the bottom of the tripod on two Vixen telescope tripods: the HAL-110 and HAL-130.  They are the same shape internally, but the screw holes are slightly differently spaced.

I have historically drilled and tapped the holes in my part by using the legs as patterns.  For the CNC project, best to get the locations exactly and use the mill to drill pilot holes.  But it the spacing is different, and there is no symmetry at least at  the .001" scale.  My guess is that some badly paid Chinese worker has a pattern for the holes for each leg.  I just hope that he doesn't damage it, because then I will have to revise my program.
