I found a convenient stainless pot with handles and set about converting it to a temp controled HLT.Bought a mashmate from mashmaster, an immersion heater from Beerbelly, a 22mm bimetal hole saw and some fittings from Bunny's. Oh and a 20mm thick camp mat for $12 from the reject shop.

The only particularly cute note is the sight gauge to make it harder to run it dry with the heater on. And the result:

Who's a happy boy then?
