Ken,


That makes for a good looking door, and it should function well!

Nicely done..

How about the exposed metal? Are some of the metal components galvanized? I think there are also safety concerns about exposing galvanized metal to the heat.

I think it is likely that the galvinzed coating will vaporize at oven temperatures as the vaporization temperature of zinc is in the 740F range. Most galivinzed metal chimney flues do not reach this temperature.

Copper and stainless are likely better candidates for doors.

I don't think any of the metal parts of the door are galvanized. The flashing is aluminum (do they galvanize that?). I'm pretty sure the expanded metal I used is *not* galvanized because it rusts like crazy when exposed.

Hope it's not galv. Zinc is poisonous at high temps. Use stainless bolts or screws that face into the oven.

Thanks for all the concerns. I stopped by Home Depot to double check the materials I used. The aluminum flashing and expanded metal are definitely not galvanized . Next time I fire up the oven, I'll check the screws, but I'm 99% sure I didn't get galvanized.

Glad to hear it, Ken. We'd hate for you to grow a third eye or something!

Alright, Ken. I've been working on my door plans, and yours seems to be the most workable for me. (Hey, I copied your oven, why not your door?)

A few questions.

What purpose does the expanded metal serve? Is that just for strength? Do you think it would be strong enough with the inside face of aluminum flashing, or is that too flimsy?

The strip of flashing that you cut for the perimeter. Is that secured in any way, or just held together with pressure?

How is it holding up? Do the handles get hot?

Let us know how it works, Mike! You are copying a pretty neat door!

Mike,

The expanded metal was used to give the screws something to grab on to so I could sandwich the insulating board in between. You could also use a solid piece of sheet metal. I figured the expanded metal would conduct less heat than sheet metal.

The strip of flashing around the perimeter has tabs on both sides and is held with pressure.

Door works like a champ! Good luck and be sure to post some pics of your door.
