OK Folks, (guess I'll do like the message said and re-post with changes)

Here's a little more video of slowly heating the moisture out of the kiln..=

... without much smoke yet but that will change later. The pace should star=
t to pick up soon so stay tuned for more as I continue to edit what I shot.

I'm also still in the middle of rebuilding the firebox with some decent pro=

I've decided to start adding some soap sized primary air holes lower down i=
n the walls of the Bourry box closer to the hobs and the combustion zone. D=
uring the last firing Rick commented on the "Dragon Tongues" of flame risin=
g up into the top of the Bourry and that the draft should be pulling that h=
eat down into the chamber. I realized the fuel was looking for air coming i=
n the holes along the top. If I add more holes closer to the zone of combus=
tion lower down the walls I think I can prevent that air hungry back lickin=
g of flame up inside the Bourry to the primary air ports even though it loo=
ks cool when it's at high temperature with flames belching out all orifices=
. There is a good shot of that in the second firing videos but we will get =
to that later so enjoy and stay in there eh.
