Greenlee step drill
A step drill (Greenlee Cat#36414) worked well. I used it for the throttle and mixture cables. Bought it at Lowes, Found it in the electrical aisle.

Bob Avery's Rotabroach tool is a delight to use for just this purpose. A little 'exe' but hurts only once.

Unibit worked here.
50 caliber is not quite large enough or it could be an option.

Follow-up: I used my trusty Uni-Bit tool and a touch of coolant to make a very round/neat 0.75" hole. As expected, it left a pretty good-sized burr on the outboard side of the hole which was quickly smoothed with a Dremel grinder bit and deburring tool. Thanks for all the input!
ps -- While an interesting idea, use of a 1911A1 was considered but deemed not legal - this is California don't ya know.

Yeah, full wadcutter, not an SWC since it can be hand chambered. Low powder load, like 4 grains?
