However, some hairline cracks appeared in the mortar on the outside of the dome. There are several, and they form a more-or-less continuous network over the entire dome. I understand it’s to be expected. As long as great big chunks of masonry don’t fall into my food, I’ll sleep pretty well at night.
I took down the lath and perlcrete that I had put up over the chimney, because frankly, it looked terrible. It was sagging, out of square, and lopsided. I built a steel frame for the chimney facade, which I will attach hardibacker to, then stucco.
I’m starting to get away from my drawing design just a bit, either to save time or to make a better structure. I don’t want to take any chances on water getting in, so after getting the chimney up, the next task will be to put a shed roof on. Nothing fancy, just plywood and shingles. Then, a little stucco around the top, limestone around the bottom, a hunk of granite for a countertop, and we’ll be all set.
