Chimney Temp for construction
 
Can anyone tell me what temperature the inside of a chimney reaches as I am looking at making the transition to the flue and I am looking at braizing it with easyflo. Would it reach over 500C.

No, nowhere near it. The inside of the chimney remains black and that burns away at around 330 C. Unless of course you overload the oven chamber with fuel and you allow flames to roar up the chimney. Even then I doubt if you would reach 500 C.

Thanks for that, I am going to go ahead with the fabrication with brazing which I can have a crack at myself. will post some pics of the process.

Stainless steel is difficult to braze. You will need oxygen/acetylene or oxygen/LPG. Good luck.
An easierbalternative would be overlapping joins using stainless pop rivets.

I was thinking of making the base part of the vent out of normal steel that can be brazed and have had the flue and chinaman's hat cowl made out of stainless steel. I have attached a pic of someone else's from FB which I think would work on mine. Any thoughts on having different metals?
Thanks

With that sort of set up in the pic you will probably get more smoke out of the door than up the flue. :(

ok, yeah that will work, but mild steel will corrode. if it's thicker as it appears to be, it will last longer.

yes, a much steeper angle would collect the smoke better.

More smoke out the door that chimney, why??? Definitely not the desired outcome that I want. With all the work put into the oven so far to fail on the chimney would suck..... Please send me some suggestions...

you need a funnel to the flue pipe.
