New Design for draft door airflow wheel and Knob

The problem with the draft door airflow wheel is that when it's properly adjusted cold it's snug because of the inevitable expansion of stainless at high heat it becomes tight.. If cold it's just a little too tight, it becomes locked up and immobile when it gets too hot.

Someone here on the forum suggested a spring tensioned wheel.. Thank you.. it's been implemented in current production and a work around to upgrade for existing customer's Komodos has been made.

This is the original draft door bolt with spring and one locked on nut.

This is the new production longer draft door bolt with spring and two nuts.

This is the new char proof wooden knob with dense refractory material to insulate the bolt to prevent the wood from being carbonized.

This is the metal insert that sits inside the refractory material inside the wooden knob and gives the wood type screw it's grip inside the refractory material.

I am in the process of sending out this upgrade free of charge to all my current and past customers. These customers need to join the form as announcements will be made thru this forum via a special owner's announcement section. I also have two other upgrades coming soon.

Wow

I know Dennis is known for taking care of his customers, but this is darn near crazy talk.

The timing of this is interesting as I was just messing with this handle the other day. I didn't like how it would unscrew itself if I turned it to the left instead of the right. I decided to use some epoxy between the screw and the wood. Of course, being a new owner, I completely underestimated how hot it got at the draft door and the epoxy quickly burned up. I then tried a high temperature epoxy putty but I haven't cooked on the Komodo since then so I have no idea how it will hold up. Of course, Dennis's solution looks a heck of a lot better.

Re: Thinking out loud...

The wood is very pretty. And I know that it's The Other Thing That Dennis Does. But I wonder if an all refractory knob wouldn't work' date=' too.[/quote']

Such a knob would definitely work but I think you would give up a lot in aesthetics going that route. Wood simply has a warmth and character that is hard to match. A stainless knob would look nice (albeit a little cold) but then you have that whole burning everyone's fingers problem which may not be well received ;-)

And this is the cow that scared the dog that chased the cat that bit the rat...

Sorry, something about reading this post right after bedtime books with my daughter. :)

Thanks Dennis!

I just got my pair of new knobs and installed them. I bet they work a lot better - putting refractory material inside the knob was a great idea!

Also, thank you so much for the new spring. Somewhere on here, I saw a thread about the spring material, being changed unbeknownst to Dennis, and the spring had different properties. I installed the new one, and immediately noticed a big difference. The old spring really seemed to apply a lot of tension to the lid when closed, even though I carefully tensioned it according to instructions, such that it was a little hard to close, and the spring would creak right before the latch was deployed. But then for some reason, it would not hold the lid in the fully open position when lifted? I dont know about the physics of springs, but it would seem that one that applied a lot of pressure in the closed position would easily hold the thing in the open position. There must be some variable in spring tech called "excursion" or something like that. (The distance each coil travels from the closed to the open position - seems like that would have an effect. Anyways, the new one makes an immediately noticeable difference. Thanks to Dennis for sending all that stuff. I know the poor guy must spend a mint in shipping for parts and stuff like that. I was not sure when I would get that, but I was surprised at the fast response regarding the knob problem too.

People, if you have any reservations about sending this company your hard-earned money, don't be. I, and others here, have all received far better customer service from this one individual at this small company than I have experienced with just about any purchase I can think of that I have made in my lifetime. When I get some more money, maybe next year, I would love to get another Kamado to go with my first!

Thank you Dennis.

Free of charge factory upgrades.

Yes, the first 46 sets of rear springs and wooden knobs went out late July.. After coming up with the new spring design, I just think it's wrong everybody does not have one.. When you buy the best it should be the best.

Same with the little spring behind the knob and wheel.. it's so great, I want all my customers to have them too..

So these are free of charge factory upgrades. It's going to take me a couple of months to get to everybody but we're making springs and knobs like crazy and getting them out every container..

If you're feeling impatient drop me an Email and I'll put you on the top of the list.. the first people had written me about charred knobs..

;);)

the new spring

The new spring nails it. With fairly broad adjustment latitude, it begins opening much more slowly than the standard one (i.e. holds much less tension on the lid when closed), and opens just to fully open without rebound! Marvelous!

There is one small potential hitch to installing it, so take a file with you when you go to install yours! The new spring material is larger in diameter (and the spring itself is also larger in diameter), and on mine, it wouldn't quite fit through the space between the edges of the hinge body between the spring attachment rod and the body of the cooker.

This space is formed by two corners of stainless that have been folded horizontal. A minute of filing on the corners made the gap wide enough for the new spring to slip through, and everything was great.

New draft door knob design

Dennis:

I finally got around to registering for the forum. I picked up the tan KK in Carson and 1.5 months ago.

We have had great meals off of it.

I like the new design for the draft door knob, particularly since the knob on mine broke during the learning curve on managing the temps.

Can you please send me the upgrade?

Thanks
