    Hey both have their place, if you want to disassemble something in the future, sheetmetal screws are best--I know that you can drill out pop rivets but screws are still better! But that is only my opinion!

    I didn't make a plan. I just used the inner arch form as the starting template and allowed a small clearance for the inner skin plus the thickness of the aluminium angle. I used that as the template for the outer skin adding an inch on each side and top to close against the reveal.

    I cut the angle so I could bend it at the corners and have no sharp edges at the corners and fitted the inner skin inside that. I used short pieces of the same size angle attached to that to attach the outer skin, drilled the holes for the rivets to assemble the two skins and then screwed the outer skin to the timber portion before assembling that part. The insulating ceramic fibre was then stuffed into the cavity and a strip of aluminium riveted to the top edge to seal the deal.

    When I attached the metal outer skin to the timber I left the timber about 1/8th of an inch proud of the metal so when it was put into the inner arch opening it is inclined to lean a little into the reveal to seal it.

    I know this sounds convoluted but the beauty of the rivets is that if you get the assembly sequence out of step you can always drill them out and make a recovery. (Learned wisdom )

    I have a couple more pics but they don't inform the process any better than the ones I have posted. I am a prolific photographer but for some reason I didn't capture this part of the build in any detail.

    I hope this wordy explanation is of some use to someone.

    Greenman - Do you have pics of the flat cut metal pieces -or maybe a drawing? I think it would be great to show the process here for other builders if you have those available

    Thanks for the compliments. I went for the simplest construction method and since lego melts then pop rivets and aluminium were the next choice.

    Great door Steve (Geenman).
    So are those rivets? I thought welding is beyond me but I don't know a thing about riveting either.

    pretty cool door (and thanks Russell Utahbeehive) I also checked out the Michigan builds door too. thanks,

    That is a sweet door. I plan on using rivets too....I've got a ton of SS rivets and no skill at welding stainless.

    That is a very nice door, one of the best I have seen.

    I too took the 'no weld' option and fabricated my door from aluminium sheet and angle. I left the top so I could stuff it with ceramic fibre and then rivet the strip that forms the curved top last.

    The metal part of the door is an inch and a half thick and the wood part of the door is the same.

    All up the cost was minimal as it was aluminium from the scrap metal yard, leftover CF blanket material and half a wooden step tread. The handle is wood as well so that part of the door is barely warm.

    I am very happy with the performance of the door and it is not particularly heavy with the timber constituting the major part of the weight.

    The pictures are the best narrative.

    Dino,

    I just saw this door that looks like no welding needed. But not sure how he did the back plate though.

    Re: Show us your Door Thread

    Here's my door post I just added to my thread - re-posting here for relevance!

    I finally got around to building a door. I used two pieces of 16 gauge steel front and back, and then some 1 1/2 inch wide steel channel for the sides and floor. For the top piece I used a flat 1 1/2 inch bar that I curved to fit. Inside I put a piece of 1 1/2 inch ceramic fiber board that I had left over from the floor of my oven. My plan was to weld the whole thing closed - but I started using stainless steel sheet metal screws to "tack" it together - and found that they worked so well I may simply keep the screws. I used high temperature caulk to seals the cracks so that none of the insulation will leak out.

    After cooking last night I put this door on. This morning, 13 hours later, the temperature of the walls and floor were still 550 degrees! Wow! Without the door I was down to 250 degrees after 12 hours.

    Also the insulation in the door seems to work well - I can easily lift the door out with the handles without using gloves. The temperature of the front of the door is about 140 degrees.

    I didn't think about it and used the same form for both. It is on the list of "next time". Utah, that is a mineralized nautilus sawn in half and polished. There is a one at each end of the counter.

    tscar,

    On your door pic it that a fossil in your concrete pour? If so nice touch!

    I agree. I wasn't really serious about the angle grinder option. If the outer arch is not bigger than the inner one then access is compromised. If made too much bigger then smoke escape out the front becomes an issue. There is a happy position between the two somewhere.

    Penny just dropped .... No room for revel. Yep I'd do a 2 piece door before I'd take an angle to the front of an oven like yours... It's to nice to butcher
