I am new to smoking and have done the following mods to my sfb.
1.Raised the grate in my sfb.
2.Built a charcoal box.
3.Made a make shift baffle/tuning plate from the stock charcoal plate intended for the charcoal grate for the pit side of this unit.
4.Extended the chimney to the grate level.
My question is would the baffle/tuning plate give me uneven temps due to the fact that the "make shift baffle/tuning plate" are all one piece and push the hot air flow towards the chimney extension.
My chimney extension is a 3" aluminum dryer duct from Lowe's which I have curved to extend from the back of the cooking chamber(stock chimney exhaust) to the front of the cooking chamber.
I am just thinking of the way hot air flows and I am wondering if this may be pumping all my hot air out the chimney rather than keeping it in the chamber where I need it.
So, should I actually extend it to the side closest to the sfb on the rear side of the cooking chamber to create a better hot air flow?
Or.....Do you think I should scrap the stock charcoal plate for some custom cut sheet metal? If I did this mod I would make a baffle with separate tuning plates.
