And I should have mentioned that I have the 1 13/64" drill already...
I got very lucky with that, a friend who's now 86 and no longer able to use his workshop gave it to me. He, in turn, got it among a stack of other tooling when his employer closed down back in the nineties. So the most expensive part of the operation cost me nothing!
You have what you need then, as the prints have already been posted. It is helpful to drill a pilot hole to the proper 0.660" depth first, I usually start with something around 3/8" or 10mm.
