Here is arguably the most commonly referenced build out there:

I patterned the HT oven I built from this design with some changes. For instance, I used angle aluminum for the frame and built the sides and bottom of the body out of one folded sheet of weld steel to improve heat retention. I used a PID and K type kiln thermocouple from ebay. Here's a few pics of the oven I built a while back. It will hold temperature to +/- 1 degree according to the PID once soaked at temperature and has a max range of close to 2300F. It's about 14" deep.
The door's not that pretty, but it insulates very well. The seal is made from high temp tadpole gasket fastened with stainless stripping and stainless screws. The door itself is filled with high temp glass fiber insulation.
