I am curious whether anyone has used the step-down grate system
described in Dick Lehman's article "A New Approach To Long-Fire
Results." I want to employ this in the wood-fired kiln I am designing
but have been nearly unable to find any detailed pictures. Thanks!

Hay Folks, Mike,
A couple folks suggested the step box to me too but I can't find any good =
drawings or construction photos showing it in use either so it has been dif=
ficult to give it further consideration for the time being. For now I'm mak=
ing the hobs on my Bourry wider to hold more log size fuel and increasing t=
he air under the mouse holes in the Bourry and Pig-nose. This setup is anot=
her way to get a long single firing alone with the last 24 hours or so bein=
g an all-nighter.
My concern was not a problem getting to ^13 in the front of the 9' long ch=
amber but getting the middle and tail hotter using different kinds of wood =
in the main stoke box, and in the side holes, and using the damper systems =
differently.
I had a reply concerning the step box in the last Hobagama post but my yah=
oo is screwing up and it got lost so thanks for bringing this part up Mike.=
If my repairs need redoing I might give some of the step features a try.
