i need an idea

Because it appears your cooker is long, I would move the firebox to the rear.

A bigger fire box where it's at know will creat a really hot spot near it.

OR................

It appears you have two pipes from your fire box into the cooking chamber.

Maybe you can run one of those pipes behind the cooker to the center.

Wassup man, This pit has been giving you problems from the start right? I haven't gone back to check your other posts but if my memory serves me right (and sometimes it doesn't, so forgive me if I'm wrong) you made that out of compressor tanks joined together which can tend to be on the thin side. If your steel is not thick enough to hold the heat in your pit, with a pit of that length no matter what you do with a firebox on the far end of it you will always have heat fall off. Have you tried insulating the pit somehow? I don't really know what to tell you. Sorry.

Cheers

Mount it in the back middle and add another stack to the end.

How far do your 2 intake tubes extend into the smokebox?
An inexpensive experiment would be to get some sheet metal chimney pipe that is able to either fit over the outside diameter of your forward intake tube--or fit tightly inserted into the inside diameter of the tube. Run this sheet metal chimney the length of your firebox and cap off the end. Figure out the surface of the intake and cut 4 or five smaller holes in the side of the chimney metal that together equal the surface area of the original intake. This equal amount of air opening will cause both intakes to flow evenly, and the small holes will delay entry of the smoke into the smoking chamber and create more even heat throughout the chamber. If this experiment works, then you could hard plumb it the same way.

if it's not at grate level I'd drop the exhaust....and if the air intake on the firebox isnt large enuff you won't get good airflow. you could use a pit calculator and take measurements to make sure it's all sized right.

Turn it into a reverse flow. Your uneven temps will no longer be a problem. Insulating it will make it more efficient, but will not necessarily make the temps even from one end to the other. The heat and smoke wants to rise as soon as it comes out the burn box, the only way to get it to the other end is with a full length baffle and then draw the heat/smoke back toward the fire box and accross the meat by moving your smokestack back right above the burn box. I had a similar problem as you do until I turned mine into a reverse flow.

Do a search on the net for Pit ratio calculator plug in the numbers and it will give ya what ya need.

i've got a calculator.. PM me your email and i'll send it right over..
