I drilled a hole in a piece of 1" plate last night started with a 3/8 inch center drill, then a 5/16 inch bit then a 5/8 then, finished it out so I could get a 3/4 inch boring in the hole with a 1" S&D Bit then bored it out to tap drill size for a 1.5 X 16TPI thread. Used a hand sharpened 3/8" HSS threading bit in a 1" boring bar for stiffness due to having to have the bit hanging out in the wind about 6 inches (had to keep carriage away for the one jaw that was sticking out of the chuck.
yep I know I probably did it wrong but I had the hunk of flat bar off center by about 2 inches.
