I have 4 hot roll plates 1 1/2" thick x 6" wide x 24" long. I had to drill and bore a 2 1/8" hole centered and held 21" from one end.
I used a Bridgeport mill, center drilled the hole, drilled a 1/2" pilot through to relieve the center and then followed with a 2" drill. I then finished each hole with 2 passes using a boring head to get me out to 2 1/8".
Altogether, it took me 3 1/2 hours to load, drill, bore and deburr, and I was hustling. Does that sound right ???
