Marcel's Pompeii Oven photos Part 2
(M) Well, as usual when you do the unconventional, things have a way of getting past you. I read that Robert wished that he had poured a slope in his wood storage area *before* he poured the insulating slab. "Oh, Great", thought Marcel, "I can learn from someone else's mistakes"
(M) If you are a "newbie" like me, you can now learn from mine. Robert, I thought I was so clever when I laid 2 sloping 1-1/2" x 3/4" screed guides inside the wood storage area and poured, first concrete ( and then the rock aggragate in the concrete got too large to pass the screed bar) and then mortar.
(M) After the 1 1/2" rain prevention slope concrete>mortar dried, I inserted a drywall screw and removed the guides, then filled the narrow channel with mortar. Seemed OK, but when I tried to use James' dimensions for the 2x4s to support the plywood, I had to accomodate the difference in height at the back v/s the front of the storage area! Also, even the little bit of slope left the 2x4s less secure on their bases.
(M) Lesson learned: Pour the insulating hearth slab FIRST, then, on your knees, pour the rain prevention slope. I'll bet it will be easier.
(M) Here come a few photos. Note that I had to notch for a tongue on the plywood as I am installing the span reinforcing steel inside the Hearth pour. Most are using the standard L angle irons on the 3rd course.
(M) The photos show the form before final adjustments have been made so things don't yet line up properly. One shot (# 25?) shows a severly bowed 2x6. I may need to buy the ratcheting straps James suggests. One shows me pondering whether to drop kick a 2x4, and the last, (#28?) shows the 4th 2x6 just laid in place so you can see where it sits.
off to a great start! better hurry up before the rain comes...oh yeah, that reminds me. better get to putting that roof over mine!...
