Insulated door ideas
I'm sure many of you have made a functional door for your oven. I'm ready to throw away the charred piece of plywood and make a real door.

If you have any pictures, plans, ideas, please let me know. All the best ideas come from this forum.

Over time, I've made lots of doors for lots of ovens from lots of materials. Early ones didn't work all that well; some caught fire, etc., etc. The attached pic shows a multiple Beta version. Very simple and cheap to make: two inch thick high heat board (K-Fac 19 in this case; SuperIsol works too) cut to shape, half inch birch plywood, cut to shape; wooden handle from a concrete float purchased from a box store; high heat automotive primer ready for paint color of choice. The plywood was spread with a very thin layer of high heat mortar (SuperWet 3000 in this case), and the K-Fac was screwed to the plywood using large head concrete board screws.

Used a bandsaw for cutting to shape. In use, the plywood gets warm but not hot; the seal is excellent (careful to leave the factory edge for the bottom).

For future reference, I've uploaded the same pic to the gallery.

The details on how I made mine are here.

Hey Jim, nice-looking door! Probably nice and light too. Did you coat the insulation board with something to seal/protect it (or rather, to protect your food from it)? My SuperIsol is very crumbly, so it would be nice if it didn't have to be encased in something.

Re: Insulated door ideas
Jim, doesn't the insulation board give off some nasty stuff? I know the board I used would get ground down sliding it in and out.

Re: Insulated door ideas
SuperIsol, the current door material for my own oven, is getting brittle after about three years of use. Time to replace it. It may be that K-Fac might have some shredded fibers given off if it was roughly handled, but this doesn't happen in practice. It's pretty inert, and the face side is coated. Don't think it should be a worry. The cut top and side edges do not face into the oven.

Re: Insulated door ideas
You could sandwich some insulation board between 2 sheets of metal using bolts. Pacific Industrial Supply has lots of scrap they could shear for you. The only difficult part would be cutting the radius with a 4" grinder.

Re: Insulated door ideas
Alternately, and perhaps more easily, the board could be sprayed with high heat BBQ paint. It might have to be renewed from time to time, but the application would be quick.

Re: Insulated door ideas
Great responses all!
Jim - does your door slide into the oven opening and has a lip that butts up to the reveal or does the whole just sit against the reveal?
Wade - How's the RV 8 coming along?
John - My wife won't let me near Pacific Supply until the recession improves... Great stuff.
I appreciate all the input!
So this is how we spend our time at the office.....

I missed your original post - I'm sure you have seen this, just another approach.
