<p class="MsoNormal"><span>That would cook so-o-o much better if you surrounded the fire with bricks. You could leave access on one side, but I think a spare piece of sheet metal leaning against the hole to close off all
air would do just as well. <u></u><u></u></span></p>
<p class="MsoNormal"><span><u></u> <u></u></span></p>
<p class="MsoNormal"><span>There is going to be a lot of air leaking between the bricks so try surrounding the whole fire. Maybe it would take 7 stacks of 4.

<p class="MsoNormal"><span><u></u> <u></u></span></p>
<p class="MsoNormal"><span>Those bricks were probably moulded using a wooden frame with 6 of so formed at a time. That same principle can be used to make a wooden frame with slots. Fill the whole thing at once, and tip them
out to dry. Same as with bricks. The technique is called “slop-moulding”. You make it wet enough to flow reasonably when pushed, throw in a load, push down a bit to fill the cavities, then strike it off with a flat stick. Tip out the set of 6 or 8 “sticks”
which may require the mould cavities to be tapered 10 degrees or so, because it is sticky.<u></u><u></u></span></p>
<p class="MsoNormal"><span><u></u> <u></u></span></p>
<p class="MsoNormal"><span>After some time in the sun they will be dry enough to stack criss-crossed for a long drying period like a week or a month. Being very dry is important.
