Now that the cabinet is built, I had to get the firebox and chimney in place. I found two 12' steel pipes in the woods, and set up a fireplace with some urbanite:
Had some old pieces of steel drum that I cut to be the roof of the firebox (which is at the bottom of a small hill)
Different view, same thing:
and then buried everything and had a few small test fires in it to see how it works.
I"ll have to move a bunch of sand away from the top of the pipes (it'll go into the patio) and then I'll get the cabinet in place. This might not work at all, but I thought I'd better get started trying or I'll never have one.
