Cylinder is best because it is the shape that best creates uniform air distribution.

The smaller F.P. can be a good option, on the Golden, the need for a low temp was important while keeping a 12 Hrs burn time and it can make it. If the door is too small, make the line in 2 sections. For the Golden, it's possible to just lift the liner and get it out of the stove from the front door.

I have taken this "idea" to Larry and he is on board with it. With "half a pot" the depth is maintained which is crucial for a good burn and the temps are still easy to control. The upside is 50% less coal is being used and I am still getting 12 plus hour burn times. I just don't see the point of putting 35 pounds of coal in when 17 will do the job during the shoulder months. Yes Chubby's are easy to control temp wise but why use more than you need?

Done right the results should be even better when the air is properly blocked off on the side that isn't being used.

The questions are what method will be the best to use to divide the pot? A "book end" type divider or a "cylinder type" insert and would Chubby owners and users besides moi be interested in such an option.
if you use one side only your removing a lot of radiant heat, either way your removing a lot of radiant heat, ideally Larry would make a drop in liner similar to the standard one which has a much wider lip at the top and a reduced firepot size holding the coal (he would make this new "mini pot" liner with less thickness than the standard one.... mind you....the mold he needs to produce this will cost him $5,000 and he might sell $5,000 worth of them in time (99% of the people who have each of these liners will only use the standard one in the end).

And that is the whole point of the project Doug. Thanks for stating the obvious! WOO HOO! :P

I guess a better way to explain it is this... you use less coal maybe, the majority of the heat that coal produces will be going up the chimney because your essentially insulating it from radiating out the stove by surrounding it with inches of think firebrick as well as an inch of cast iron as well as any air/gaps between the brick, the cast and the steel barrel of the stove (all these things combine to make a fairly efficient coal stove into becoming a fairly inefficient coal stove)... so what you "Think" your saving in coal vs living area heat is really less than you believe (this is to say nothing of the added expense, clean up, hassle, storage and work of dealing with it).... if its done... the original liner should come out and a different liner then utilized (that would be the most effective way to do what your suggesting and frankly... the "right" way to do it (If Larry was gonna do it...im sure he would want it done right. I just know its been done without marketing success before (not to say it wouldn't be nice a to have that option available, the REAL question is... is it productive for Larry to actually do it :confused:

Doug

Read my first post prior to posting a diatribe. The concept for this is for the "shoulder" months when a full pot of coal isn't needed and last I checked you aren't currently using a Chubby either.

WIll this project come to pass? I do not know. But we both like the concept and from my own meager testing using firebrick it works. Using the firebrick right now as I type this and have been for two weeks. It should work better with a proper divider that is designed to fit. Is it sellable? Do not know. That is why I asked Chubby owners and users to chime in. After all. A divider desgned to fit a Chubby won't exactly fit any others stoves.

I will be the first to say I currently know nothing about coal but what would happen if a filler that was a cylinder is fitted and basically have a ring of burning coal between the original firepot and the cylinder shape that is a filler.

Will not work as coal needs a compact mass, a thin spread out bed will go out or require a very strong draft with short burn times.
