I just recently built one with openings from the CC to WC and FB to WC, I've only done 5 cooks on it but I really like it. I can run the CC and WC at the same temps or completely different temps with no problem. I'm not saying that you can't achieve the same results without the opening but it doesn't require a lot of extra work or materials so I feel it's worth it. If you have an opening from the FB to WC then you'll need a stack on top, if you just have a WC with no opening from the FB then you'll need a vent near the top of the WC so you can dump some heat if needed.
Yeah, makes sense. It will be easier to put it now then later. I didn't put the stack on yet, because it's much easier to move around with the eyelet. I'm planning on a round 6" exhaust on the WB and a 6" square inlet from the FB. Thanks for the input.
Eyelet is great....I cut my hole then tacked a scrap piece of heavy bar across the hole (on inside of the warmer) to allow me to pick up. Even with the chiminey attached, I could fish my chain down to the bar.
Getting started on the doors for the FB and WB. First I had to get the warpage out of the 1/4 steel. What I couldn't beat out with a maul I use the forklift.
Putting in a removable drip pan in the WC. Have a 1" pipe going into a 1 1/2" pipe that I will install a valve on. Not sure if it's the best idea, but I don't think it will hurt.
