I have started on a large project; 5.5" with a 4" motor mount. I am adding an Aeropack "flanged" motor retainer, and I am getting a bit antsy; I have my rings prepped and ready to go, and then I noticed that the screw holes in the flange are barely larger than the screw mounting through them. To make things a little hairier, the match marked and drilled holes have zero room for error. if one hole is drilled a little off, the hole flange mount is wasted.
What is the best regarded method for insuring proper alignment for drilling holes that all 12 will mount without issue? Pictured below is the final ring assembly, and I have marked the hole centers with a Sharpie. I have one chance to get it right, lest I have to scrap the assembly and start over...
