Got the oportunity to flash the oven up only 3 times since the new door was made, due to rain, general business and more bloody rain!

As you can see the silastic doing its job and the doors still together!
Theres a coupla dings and chips , but I expect that. I noticed that the bright white colour has deminished a bit and its starting to get a lite brown colour in sections...the old door was well browned off. Its also lost the powdery white residue of freshly cut hebel gives off.
I'll now take off the extra layer off plywood and replace it with a hardwood face and oil it. I'll also carry a strip of wood around the edges to protect the hebel edge but just off the brick so it won't burn. I also scored some new handles to replace the old ones off my tool drawers.

Finally got around to fitting that hardwood face (only taken me 6 mths)

A nice piece of blackbut come my way with the handles it looks pretty good.
The doors still together the silastics held up. I now realise that the oven door usually goes on with the temp about 350 C so the hebel must protect it to that temp at least. With no bolts through the door these no hot spots and the surface of the door and the handles are always cool. The only disadvantage is of course the hebels brittle I have one small chip in one edge it doesnt effect the doors operation and you certainly can't see it so I can live with that. I made a wood door just out of a packing crate as I could find little about them on the forum. It was a lot of fun and it worked well enough so I have the following link which might be of help to somene ( the wood doors at the end of the thread)

Hi Dave & Others,
I found this thread describing how to make a door from an aerated cement block very helpful and it has prompted me to start my own project - thank you all. I do have a question about the suggestion to use "roof and gutter silastic" as an adhesive. Did you use straight roof & gutter silicone (which I always assumed was a sealant only) or did you use something like liquid nails (not sure this would be safe?)
If any of you could let me know what product you successfully used that would be a big help to this newbie!
Thanks,
Phil

Phil, I think any high temp silicone adhesive for fire place installs etc. would work. The handle screws I would think could be screws into the blocks just not all the way through? Not certain on that just a thought I was considering. May transfer to much heat to handles.

G’day
works with silastic because you have the airated cement sheet to protect it from the heat! Used gutter sealant because it’s designed for exterior use. Mines still together after 8 or 9 years now battered yes but still doing it’s job.

CobblerDave,

Your oven door inspired me. Although not exactly like yours, your use of aerated concrete reminded me that I had a few insulation firebricks laying around that I might be able to use in a similar manner. I cut the bricks in 1 inch thick slices and glued them to a wooden door structure. Then I glued a cake pan to the IFBs. The pan fit perfectly into my door opening. I filled the pan with ceramic fiber blanket. I used 700F capable gasket making silicone as the adhesive. The door works great.

I attached some pictures.

cough cough sneeze …… this threads getting a bit old and dusty like me and the oven.
Well the sons put the door just out of sight beside the oven. By the time I found it it had been in contact with the ground and got the dreaded dry rot.
Used it a couple of times then the boards came straight of the rotten ply. The hebels hopelessly cracked now so I built a new hebel back to go on the hardwood boards directly as they have no rot.
Oh bugger $20 for the hebel not $5 and $9 for the gutter silastic. Recon it’s worth it as I hope to get another 10 years out of this one lol
