Small hole, just spot with a center drill and have at it with the pre-ream size drill in one shot.
This Thursday a 30.25" Dia. X 3/4" thick plasma cut disk, 304-304L stainless clamped to an aluminum faceplate
Center drill, had to use a taper extension to get across the gap which I had to remove followed by a 1/2" drill thru.
Drill thru with a 3" drill, this is not a pleasant operation with the tail stock.
Bore 5" thru, counterbore 9.83" X .550 deep, turn OD 30.00" and face entire part, it turned out reasonably well.
So have at what you are trying to do, if you worry about every possible detail it will never get done, if you bugger it up so what, make another one. Above all other considerations have fun and you will also learn a good deal in the process.
