Firepot
From Cornburning
I will start this with a link to the old forum which has a few ideas for fire pot design and for now a couple pics of a working home built fire pot

There are many designs but the underling principal are basically the same. A fire pot consists of a vessel with holes, slots or some other means that allows air to be drawn or forced through the corn or pellets. It may have a permanent air shroud surrounding it or it may set into an air shroud built into the stove.
Materials
Fire pots have been built from stainless steel, cast iron and high carbon steel. There has been some mention of cracking with the stainless pots and cast can be a bit tricky for the average D.I.Y. so perhaps high carbon steel might be the best bet for a home built burn pot.
Here is a link to picks of a bottom feed type burn pot http://www.edzone.net/~debsherr/cornburnerpowerpoint_files/frame.htm
Below are a few pics of different types of fire pots
The fire pot on the lower right is a home built bottom feed burn pot, some adjustments were made to the air input to accommodate the bottom feed. It was quickly cobbled together and worked so well I just couldn't part with it, so I just made adjustments until all the feed mechanism worked right. So don't give up, if you can get a good fire even for a little wile, you can always make adjustments to the air flow and feed rates later.
