OK, you guys are killing me. I guess this is where I post the formal apology to sandman and 3RRL - sorry to ever doubt your machine shop prowess.
Thanks Danno for making real the saying, "be careful what you ask for."
Shall I further highlight how handy I'm not?
At least you all will believe me when I say that I'm not so handy. I think I'll just have the dude come torch it since I'm obviously not qualified to drill this hole.
So to break this down:
1/2 inch hole, 0.5 inches, 12.7 mm.
9/16", .5625", 14.2875mm
17/32", 0.53125", 13.49375
33/64", 0.515625", 13.096875mm
Keep in mind I can't exactly plop that bucket on a press. So by
hand, holding the drill
horizontally, probably with
one hand while dripping oil here and there, kneeling over in the dried manure on the floor of the barn, under dim indirect light, while sweating profusely... I'm going to drill this dang hole??? I can say one thing with almost absolute certainty. I could drill that hole with any one of those bits and I bet CSI couldn't ascertain which bit I used by looking at the hole!!
After further thought, I think I'm just going to use Gorilla Glue.
