Stainless smoker build - Page 2

post #21 of 34

Kory,

Unfortunately there are no calculators for insulated smokers.   

Best to get it in the ball park range with Dave O's reverse flow calculator (click on the reverse flow section).

 

If you could figure a way to insulate the heat exchange tubes would be good as that's where a bunch of heat loss will occur.

The smaller the tubes, the more friction you have.

 

 

2 x 3" tubes probably will be ok or even go to 4" on a  20 chicken sized cooker like yours.

 

yes a water tray will help just try everything you can so hot flames are not blasting onto your brisket.

 

i would make the chimney anywhere from 1/2-3/4 up the CC.  

 

You want to get good airflow through the cooker

Thanks for the advise bro, I was thinking 3/4 down may be to low and the hot in coming air would escape the low exuast. I think I'll go 1/2 to 5/8. I'm gona go with 1/4" wall tubing or so , not sure if I'll be getting tube or pipe but I may wrap them in header wrap insulation.

You can buy 3" mandrel bends online for exhaust and yes header wrap will work. That stuff usually rusts regular pipe but with stainless you will be fine.

That stuff would be spendy and only 16 gauge. I'm going with 1/4 and I'll just be pie cutting it and tig weld. Thanks tho. I'm also no far from Columbia river manderl bending
