I've got this electric brew kettle: http://www.maltbazaren.dk/shop/elgryde-rustfrit-staal-1454p.html
The problem is, the hole for the outlet valve is too small, and the spigot is this crappy plastic thing. I need to upgrade to 1/2" fittings (at least, I think I do) but am not sure of the best way to go about this, having never done it before. My understanding is that there's a conical attachment you can get for an electric drill that's supposed to ream it out to whatever you need, but I have no idea if this is the right thing, and if it is, I have no idea what it's called. Any thoughts?
Thanks! Headed to the hardware store today to get way more copper piping than I probably need.
