adjustable throat

[PetesMeat]

Hi Everyone,

Thinking about doing an adjustable throat opening on my centre feed.

Just wondering, how is it used, and what does it do? Close it off and improve fuel life?

I believe Frank and some others have built cookers with the adjustable throat. Hopefully one of them will chime in soon.

Centre feed....where's Gizmo ?

Gizmo made one with an adjustable throat a while back but I don't think he had any luck with it. In theory if your recommended throat was 50 sq in you would make a 75 sq in opening with a plate that is hinged or slides over the throat and you could increase the max temperature in your smoke without building a raging fire. I think RC has one on his smoker and he closes it of while he has his smoker open so he doesn't get smoke in his eyes. It will probably take a lot of trial runs to figure out what each adjustment does but I think it may be worth the trouble.

When I had asked Gizmo about his findings, I was at that stage of the build. His advice was it wasn't worth it. I am reasonably sure he'll be here to clarify his points

Where is Gizmo? I have one and it does work, I can close it if it is windy and I'm adding fuel to limit ash issues. As Big T mentioned I can close it to keep smoke to a minimum while checking the cook. But I can open it all the way and it will allow for a quicker initial heat up, then choke it down to the recommended size for smokin. I think the experience Gizmo had was because it was a thin plate being used and the heat transferred right on through it. But as some of you know I don't go thin on much of anything and it works so that is my rational.

I think RC is correct on the one I built for Earl.

But - on a centerfeed it must be a little different.

Edgar had a happy temp of 225 to 230 when I first built him per the pit calc.
I wanted something higher.

So I cut 2 - 2" X 4" openings - one on either side of the top hat (first baffle)
I then put controllable doors on those openings but discovered after several burns that I was always leaving them wide open because it gave me a happy temp of about 260. So I put them in a sack and gave them to his new owner in case he ever wanted to play with them…..

One time I met a lady who had an adjustable throat.
