    I was thinking last night (could be dangerous) about my plans to modify Gunny into a smoker and thought I may be trying to hard to perserve the original 1944 military oven parts especially in relation to the exhaust damper. Bbally had figured I needed 10 sq. inches of exhaust for this thing. Drawing on experience in other areas (I certainly have little in pit building) I came up with this.

    This is a all metal 4" blast gate for dust collection systems. My concern was the galvanized blade. SS is available but very expensive. This one can be bought for 12 bucks. It is already flanged on both sides for pipe. A 4" has the equivalant of 12.556 sq. inches of opening. As to the galv. the entire unit is outside the cook chamber of a smoker being designed to run 375 F max well below the 600 F gassing temp often talked about.

    The housing is aluminum and can be taken apart for cleaning with screws. These screws in the housing would seem to make it possible to run a high heat sealing compound around its parameter and bolt to the smoker. What do ya all think?

    Rick I cant see the pic, sounds like it would work.

    I used a regular stove pipe damper for both input and exhaust. I was lucky and found some 3 inch stainless tube, and extended it with aluminum dryer duct. I would not be affraid to use the galv outside and at low temps

    Keep the ideas rolling, I just picked up an all aluminumn food cart. Its not insulated yet but has lots of potential.

    Not exactly shure why i need another smoker, but somehow it just makes sense.


    They are available in 3, 4, 6, 8, inch

    Just heard from ebay and purchased this SS Gate for 20.00. Had 9 bucks shipping but for all SS well worth the money..

    Looks like a vacuum slide gate???

    That was a steal at $29 for SS!

    Yes that is exactly what it is. It is also called a blast gate by some. I am happy with the purchase. Thanks
