    Kind of a recap for those who have considered how to lower chamber temperatures , hold in the smoke, and get a longer wood burn.

    I installed a valve using adapter fittings to join a 1/4" NPT valve to a #6 SAE flare fitting. Made a cast iron chunk pan using a chinese cast iron 10" skillet and carriage bolts for legs. And sealed the doors with some nomex 1/8" thick gasketing. This smoker is my main go to for small batches. I use the big PS4400 for large loads.

  2. I am heading to Home Depot later today to purchase the additional parts.  Should be an easy tweak.  Thanks for the info!
  3. i bought some parts at HD but didnt hook up bc im not sure if they are the correct parts.  Did you buy any other parts other than the 1/4 NPT and #6 SAE flare (assuming 1/4 male on each end too)?  I buying off amazon now.

    Thanks for all the help.  My temp is still running high.  I realized too my unit doesnt have sidevents either

    I've been reading about these needle valves. Where do you get them? My main concern is that looking at my lowest flame, how much lower can I go without worrying about "blow outs"? I have nomex seals on the doors, and just leaving the door set open a little keeps the temp at roughly 240.

    The bbq store here sold me a ball valve and said it would work. Do you think it will work as good as a needle valve?

    Not at ALL!! Ball valve is meant as an on-off device. Needle valve is for adjustments. You can get there with a

    ball valve, but a very small movement makes a very big adjustment.

    I agree. It will work in a pinch, but VERY tuff to adjust. I was doing some chickens, and my needle valve didn't arrive on time. I installed a gas shutoff valve in a pinch. The tiniest adjustment on the valve made a big difference in the flame. I was constantly adjusting to keep temps steady.
    I swapped it out as soon as my needle valve arrived. Very easy to keep temps where I need them.
  8. Do you open the valve on your tank and the valve on the smoker all the way, and then just use the needle valve to control temp?

    I open tank about an eighth of a turn then burner on high to light. Keeps the excess flow valve from triggering. Then I open tank about a half turn or so. Adjust main burner valve to low. Then I start using the needle valve. So I tune the smoker control with the needle valve. Has been working well this way on both my smokers for about a year now. Needle valve takes about 3 turns or so from wide open to start effecting the gas flow to the smoker.

    What kind of needle valve did you buy and where did you buy it?

    I have not done a thing but put a cast iron pan for wood chunks and played with the top vent and I'm holding at 235 and I'm doing a 15 pound prime rib and auju in my smoker

    The trick is to let it be I run it for an hour before I put it in

    Has anyone tried using an adjustable regulator like this instead of the needle valve? What are the pros/cons?

  14. Froman, should work the same. $20 regulator, or $5 needle valve. They do the same thing on my brew equipment - I use needle valves for my hard piped multi burner stand, and a similar regulator for single burner set up.
