Hi all --

I have finally decided (after ogling the bread photos at cookingwithcrack.com) that I MUST assault a pressure cooker for my own personal benefit.
I am awaiting my $8.99 ebay prize now, but am hoping that someone here might humor me and tell me WHAT tools to use to drill the hole in the lid. I've got a drill and a set of high-quality bits, but -- could it be that simple? The thought of drilling metal is kind of scary.

Also -- how big is the final hole? The size of the fittings? I DO wander around the hardware store just to stare at all the nifty assorted hardware pieces with infinite project potential (what could I do with THAT?), but I have no experience with plumbing gear. All of the stuff at http://www.cookingwithcrack.com/bread/steam/index.html is stuff I've seen, but I couldn't tell you anything about them, and if I go shopping right now, I expect I'll be confronted with too many choices to get it right! What do I need, fitting-wise, for the ends of the braided line,and to connect that part to the copper tubing? And are they both about 1/2"? I definitely know the bit over the hole is NOT called "a hex-shaped nut-lookin' thingy with an eyeball."

I've found my oven vent, right where it always was, but can't figure out if I should unscrew the little screen (attached inside the oven) so that the copper tubing will go all the way inside -- it sounds logical, but will it wreck something? Is the screen there just to keep crud from hitting the oven floor? I don't think I'll have to drill anything back there, at least.

Eternally grateful for any help,

Tara
