Also a tube is much stronger than a flat plateIt’s the cooling effect of the secondary air that keeps the tubes from sagging and the SS alloy.

Why not just use the baffle that came with the stove?I will keep updated as we start to burn more. If it's a failure I will gladly share that with pics. Good news is they are a perfect fit so easy in and easy out
I like to tinker, I think I can do better than us stove co. This stove has proved itself so bad I'm factory form there is nothing to lose by experimentingWhy not just use the baffle that came with the stove?
No secondary air at all? I wonder if letting a little in would help with a little more efficiency and cleaner burn? I know the EPA doesn’t care about efficiency or burn times they just want to see a clean burn. I think many manufactures know this and just dump more air into the stove to achieve the EPA requirements. They tune the stoves to run on a 15’ chimney in ideal weather conditions. There’s just too many variables for every setup so I can see where some stoves will not act as advertised. If people had more control over primary and secondary air into their stoves they could fine tune it better to work on their own chimney. Blaze King has a thermostat to control air, PE has an EBT to control secondary air and a few other manufacturers are tweaking secondary air as well.@bholler I admit defeat on the baffle idea. We are doing a small fire tonight and with my genius mower blade baffles alot of heat was going up the chimney. Original baffle back in. Gonna buy another cut to fit ceramic fiber board to put on top and extend forward a bit to slow it down more. Still dead set on the "smoke dragon" conversion for now. There is no air to secondary tubes and she's running nice and steady. A much more controllable burn I have a feeling I will get some long long burntimes like this but time will tell when the cold weather comesView attachment 315413
See what others have done here. Secondary combustion I think is always a good thing of you can keep the correct primary/secondary air ratio correct. In my tinkering with a stove that has only primary air control a damper or three was the only way to keep the ratio correct.@bholler I admit defeat on the baffle idea.

Yeah that stoves is really dialed in! Seems like most of the stoves he’s tested are like that. Those slow lazy flames are hard to come by on most non cats I see but I’ve seen them often in cat stoves. The cat also acts as damper or restricts the flow from the firebox. I think he’s good on clearances, he has a how to video on his hearth.That control over the flame is extremely impressive. I also found it a little funny how he said it was a large stove where over here it would be considered tiny. I wonder what the clearance requirements are on it as it’s only a few inches off everything with no hearth pad or protection.
Nope...you need the fuel (woodgas), the heat, and the oxygen (preferably superheated) take one away and you just get smoke.A "secondary" flame will naturally happen whenever a fire is burning clean enough. Like a smokeless campfire. Isn't the smoke burning all that a secondary is?

DIY turbulator anyone?
So I’m considering a DIY turbulator. What is it? See Jotuls diagram #73. It’s a structure that increases turbulence above the baffle to increase heat transfer to the stove top. Why? I’m trying to dial in a self diagnosed over drafting insert. It has a damper but I’m still not convinced...www.hearth.com
If you have a fire burning correctly like a campfire all the smoke is burnt anyway. I guess that's what I'm having a hard time understanding. If a smoke dragon style stove is burning correctly there shouldn't be smoke, so how are the tubes any more efficientIt burns the unburnt woodgas otherwise known as smoke. Getting you more heat from the same amount of fuel and burning cleaner
A campfire is never really that clean, or efficient...if the fumes were collected you see plenty of "smoke" and unburnt fuel.If you have a fire burning correctly like a campfire all the smoke is burnt anyway.

Running the way you have it now, you will have to sweep the chimney often.
I'm talking about with no baffles or anything...just a "campfire in a steel box".I would disagree, as long as his wood is dry and his fires are hot enough he won't be producing excessive creosote just because he doesn't have a secondary burn. It's certainly not running as clean as it would, but shouldn't be making more creosote than it would.
So make your secondary air regulated...many people who have added secondary air to old stoves have some sort of valve on the intake...often a ball valve. How does having secondaries make a stove more efficient? With the unregulated air blocked I can make it run slower.
