Now you have a pattern, to locate the hole.

For the bigger geeks, I then scanned the outline, brought it into my CAD software, and copied the cover shape, and put a center mark on the hole. Printed it, placed it over the cover, and drilled.

Note, I managed to use the words "shaft", "inserted" and "hole" without giggling...

I laughed at the words "locate the hole" but good looks with the paper. I was on the fence about using pieces of painters tape adhered around the shaft but didn't think they'd hold the same placement when I'd have peeled them off but I'll give the paper-method you suggested the next non-rainy weekend
