Production Woodstock IS

The opening would be sized such that it could run wide open indefinitely. The size would have to be determined through experimentation.

And yep, if one is going to do things like this (open ANY door on a woodstove to 'get it going') and walk away, well then bad things are going to result. Frankly, I am amazed that your stove too 1 hour of the ash pan door open on a full load of wood without significant damage.

'Fire makes and excellent servant but a terrible master.'. Heard that some time ago and have not found any fault with the logic yet

Give that man a cheroot!

That is a slick setup with a hobby R/C servo driving the turnbuckle to control the draft. It looks like some factory parts (the turnbuckle, the draft wheel itself) combined with some home- made stuff (the holes cut into the painted sheetmetal, the stand- off mounting of the servo) put together to make a great gizmo. Something like that would be ideal although I would add a magnetic coupling and a large weight so it would be self- closing in the event of a power loss or ECU failure.

Great post Brian- thanks!

I found that photo on a BBQ forum:

He goes into detail with the set up on his own blog:

BDF , sent you a PM with info on the above mentioned subject.

 

That is a very well done hobbyist fabrication IMO! Thanks for posting that. Same thing will work on a wood stove too although of course there would be some kind of shield needed so hot coals or sparks could not go through the vent holes.

Stretched the IS legs yesterday....
Left the house at 8:15 am for church. Loaded up the stove before that... maybe 7:45-8 am. Set the draft down to 4. It was a windy, cold, snowy, Sunday. Got back around 8:30 and the stove was still warm with plenty of coals for a relight. The house was cool, but not too bad. I loaded it back up, got the wood charred, and engaged the cat when the temp came up. Let her run for a couple few minutes and then turned the draft down to 1/3 (maybe notch 6-8). Came in two hours later after clearing a foot or more of snow and it was a little hot. Stove front temps were JUST under the red line (650?) and my stack pipe temp was also JUST under the red line. The wood load was all bright orange and my andirons were a little red. Turned her down and she settled nicely.

Lately I have been loading N/S. I bought some wood that ended up being a little too small for perfect loading, and my wood from the other stove needed to be a max of 16-17". With 18" logs, it loads just about perfect for N/S. I have also been raking the coals to the front to make the coal bed parallel to the stove top. This seems to burn the wood hotter, faster, and with fewer coals. If I want a really long, slow burn I can load E/W and do a cigar burn.

 

Wow, your powers of prestidigitation are truly prescient.

Just got an email from Tom at Woodstock, looks like the first batch of Beta Franklins are going out real soon, and the second batch in a couple weeks. I've got a late winter visit to East Lebanon NH in my crystal ball...

 

This is about to get real interesting..... I really would love to see the internal concepts of this stove replicated with different exterior designs other than the Franklins. =)

Hybrid: Version 3

We are finally building beta stoves for our next (as yet un-named) steel hybrid. This will be our third hybrid: first the Progress, then the Ideal Steel, and now a high performance woodstove with record-low emissions. The combustion system in this version has some significant innovations to lower emissions.


Ivan welds the top on a new beta
The new hybrid will again be made of steel, to keep the final retail price firmly in the affordable range. It has a soapstone or refractory liner, right or left door, top or rear exit, and will be available in several styles. Firebox capacity is approximately 2.5 cu. ft.

Ivan & Joe checking fit
The first few new beta hybrids will go on our test stand to verify that changes we have made to the “plumbing” won’t effect performance (they shouldn’t), to calibrate the bimetallic controls we are using, and to confirm that none of the innumerable recent changes influences emissions, output, or ease of use.

Are we finally looking at an automatically operated woodstove? It seems like that would be the next step.

 

Two times a beta tester. You're the envy of many a FHC member. Did you son and crew see their future exertions in the crystal ball too?

You'll be stopping in West Leb by the way. The only thing to do on the east side of Lebanon is ice fish on Mascoma Lake this time of year.

Drop me a line when you're in town. I'd like to see the new stove! It's good to hear that they've had some time to tinker with the Franklin.

 

I'm going to bribe some friends...same crew, I just have to up the bribe.

Oops, I just Googled "East Lebanon NH" this afternoon too, in anticipation of another trip up northeast, and couldn't figger out why it didn't come up on Google maps.

D'oh!

I'll let you know when we're swinging through.

 

If you want some serious heat, throw a load of dry mulberry in this stove. Craziness.

 

We just moved up from cherry to a combo of ash, hard maple and a bit of locust. What a difference. I'll get into a good bit of well seasoned oak next year.

 

I'm not sure what to think about oak in this stove. It burns a long time but does not make the stove really hot during a cat only burn. Is it possible that it does not off gas as much as other woods? Either way I get really nice burn times. The wood is seasoned 3 years.

 

I can't honestly answer that. I do know they are working on even lower emissions than the Ideal Steel, but I don't know the details yet of how they are going to achieve them, though I've heard some "rumors." Beta testing should be interesting to see what they have up their sleeves.

 

From what I saw at the factory this summer, makes me want to limp the fireview along for a year or two until the dust settles.

 

Thanks, started it a couple hours ago:

Woodstock's next Hybrid: Version 3 (Franklin Hybrid?)

 

I am about 2 1/2 weeks into burning my IS, still running with the damper closed for the entire burn once the cat's lit.
I did start to notice a bit of ash build up Monday AM, ash pan was full, took 17 days running 24/7 to fill it.
There have been some pretty cold outside temps for Rhode Island lately.
Filled about a half a hod with ash, a very easy and clean deal. "my 1st stove with an ash pan"
I have been burning some lower quality wood the last few days, I harvest all my firewood myself so if its wood it goes in the pile.
Some pine some punky a little mountain laurel and other oak and maple odds and ends, its just what's next in the shed.
About the only difference I seem to see is that I am only getting 10/11 hour burns instead of 12/14 with the nice oak splits.
I really just want to empty the shed's of this wood so I can fill them with the good stuff, these limbs have been in here since 2011.

One thing I have noticed is the paint on the burners, We picked the forest green and charcoal body, the green on the burners has faded to almost match the charcoal, the door and sides are ok. Not a big deal just noting it for others.
Amazed that I haven't had to clean the glass once, its a little hazy at the end of the burn but clears right up with the next fire.

Still loving this stove everyday! It was 2 degrees out last night. 74 in the stove room this morning after a 10 hour burn.

The cat always seems to be around, wanting to see everything.
