nono we still doing the reverse flow that you gave us dimensions for :)
Thought it was called baffle plates the plate that run the heat from firebox to the end and up over back :D
i thought it was 1 full plate from one end to other. did not know about "tuning plates" :D so glad i asked haha :D

For the "Reverse Flow plate", 6mm is a good thickness....

sounds good! :D was unsure what the plate was called haha.

how big of a gap should i leave from the end plate to the end of smoker for the smoke/heat to go up?

edit.

Chord AB (~19") should be the width of the RF plate..
58 sq in. is the area... / 19 = 3" width... since that will create friction, I would go with at least a 5" wide gap...

 

[daveomak]

Volume in cubic inches X 0.004 = FB/CC opening in square inches
14547x.004 = 58 sq. in
Volume in cubic inches X 0.004 = Area under the RF plate in square inches
58 sq. in
Volume in cubic inches X 0.004 = Area required at the end of the RF plate in square inches
58 sq. in

4" exhaust stack ~36" above the CC...
air inlets to the FB, ~15 sq. in.. 20% upper .. 80% lower...
1" firebrick won't affect too much...

So upper would be say 1.6" tall 2" wide and
lower say 2.4" tall 5.2" wide?
that should be just around 15sq in right? "or 15.5 or something"

would that work for the air inlet? Im not so good with math, but i think i came up with the right numbers for them:P?
Planning on just doing slides

Getting there!
got firebox and RF plate in and exhaust on today :D

planning to have it done by friday!

So finish the small things like grates and wood basket tomorrow. then paint, and then we doing a burn out in 2 days.

so excited! and thanks dave for all the help!
