Inspired by this stove and the mesh floor in Colin Krusor's rollup stove (found here: http://www.backpackinglight.com/cgi-bin/backpackinglight/forums/thread_display.html?forum_thread_id=44302), I thought that maybe a stainless steel sink drain cover would work to create a false floor that would allow airflow up under the woodfire without having to balance the stove on a separate piece that makes it less stable. The mesh has a 4.5" diameter while the opening is 4.75", so it's held in place with two titanium stakes.
I got to try it out the other day while camping on one of the Boston Harbor Islands, one of the few places in the area where you can still have a fire on a beach. We had a little fire for roasting hot dogs that was dug down in the sand and had a windblock around three sides, but was still blowing horizontally, to give you an idea of the wind. Meanwhile, the little IKEA woodstove worked great--just a handful of sticks and it got my mac and chili boiling. Every couple minutes I lifted the pot off and dropped a few more little sticks in. Everything burned to ash.
Perhaps in less windy conditions there would need to be an opening cut in the side, but the uncut caddy worked great for me, and couldn't be easier to put together.
