Best way to cut a 7/8ths hole in a stainless pot?

[GooberMcNutly]

I am getting my first full wort boil setup soon. I will need to cut some holes in the side of the pot. What is the best way? Hole saw, then clean up with a Dremmel? A punch-cutter? (Will that work on a curved surface without banging up the curve?)

Has anyone tried flattening the side of the pot a little to get weldless fittings to seal better? Or does anyone make a curved washer to go between the nut and the O-ring?

I use step bits with a little machine oil or Olive oil for lube.

Thanks Push, just what I need, another excuse to buy something from Harbor Freight.

They also have them at your local HD, Lowes or well stocked hard ware store. In case you need them earlier.

I just use a titanium drill bit thats carbonitrided. With my 1/2" rotohammer, this makes for quick work porting through a SS keg wall. Also, my 4.5" angle grinder makes quick work of taking off the top too.

Prost!

or as the pope may say...

If you have some lube thats...uh...good enough to use in sex...it's good enough to drill with...

I was wondering why no one uses a plasma cutter for cutting these things. I know that they are a bit pricy, but they do cut the hell out of most metals that I've come across. I was also thinking about this for the top of a keggle.
Any ideas why this will or won't work?
