There are lots of questions about oven doors, but no official door thread. I thought it would be useful to consolidate a bunch of examples that showed different ways to build oven doors.
I'll start it off!
Door material:
Face is HOT ROLL SHEET / PLATE 0.060" (16 GA) Hot Rolled STEEL
Thermometer protector is HOT ROLL TUBE - SQUARE
0.625" OD x 0.065" Wall A36 Hot Rolled Mild Steel Square Tube
Insulation: Two inches of ceramic fiber blanket
Handles: Gate handles purchased from Home Depot. I was cautioned about using metal but they don't seem to get hot.
Cost: ~$55 if I don't count the welder. About $25 for the metal from Onlinemetals.com; $5 for the handles; $25 for the thermometer (from our hosts); Insulation was leftover from build
Weight: 10 pounds
How it's built: I cut the metal with a metal blade in a jigsaw. Outside plate was based on my entry arch form less 1/2 inch all the way around. The inside plate was based on my oven opening arch less 1/4" all the way around. I cut a 2" strip of steel to go around the outside and welded the whole thing together with a HF cheapy welder that I bought off of craigslist. The door was the first thing I ever welded - and it took a lot of grinding to get it smooth, but it came out pretty well. Took an afternoon to weld it.
How does it work: Pretty well. My temperature ramp about 100 degrees loss a day from the oven; third day temps are in the 250-300 degree range. Thermometer reliably reads 50 degrees lower than the temp my IR thermometer shows for the inside of the oven.
Favorite thing about the door: the weight.
What would I do to improve my door design: I could have made it deeper. Making it 2 1/2 or 3 inches deep would have given more insulation and not cost any more or taken any more time. And I still might add some rope gasket around the door to get a better seal.
EDIT: I finally added the gasket and let me say, it makes a HUGE difference in heat retention. I used a single strip of Lavalock felt gasket tape, and my oven is now hot a week after i have a fire. It's 600 degrees the next morning, Incredible difference!
