I just measured up my McCoy 049, thinking that whatever the mounting dimensions are, they'd round to some easy fraction of an inch.
I was wrong: it looks like the radial mounts are on an equilateral triangle, 0.837 inches (+/- 0.005 at least) on a side. This doesn't seem to round out to anything sensible.
So -- anyone know for sure? I'm really not good at measuring hole centers, as I find out whenever I finish drilling something up and go to try to bolt it onto something else.

Frankly, I tend to have the same problem whenever relying on measurements to locate mounting holes. Just set the backplate, or tank back, or whatever carries the mounting lugs, where you want it and mark through the lugs themselves. I do this with beam mounts also. (Almost) foolproof; if only I weren't so good at doing fool things...

Well, you're too late. I've already drilled my test stand from measurements. I can't say I nailed it, but everything fit on the first try (using a 3/32" bit instead of a #43 helped).
