I decided to keep going with the ideas I've had for increasing the volume =

ir under the fuel in the Pignose and Bourry mouse holes...
(click picture or next for results or previous for setup)
My thinking is the air coming in gets heated on the way and expands in vol=
ume two or three times at the coal pile. Let us now pray the warped shelf s=
tays in one piece. I can also see something of the step firebox in the mous=
e hole profiles with a long tread and short riser. This should work just as=
