The winter is over, the weather has warmed up and I am way behind schedule on the building. I had wanted to be cooking pizza before it got warm in theNorth Carolina, but the colder than usual winter got in the way. Now we always have cold times during our winters, but this year it seemed to never get above 40 degrees for more than a day or so at a time. And building the brickwork for the dome seemed to be an important part of the process, so I wanted to get it right,
On we go! I had my floor laid down and all the bricks cut in half. The “I” tool was ready and had been tested and worked well. I just needed the fire mortar. What a shock. I had to order it from the brick supplier and it cost $85 for 50 lbs. I thought I would buy 3 bags and just go with it till I found out the cost…. One at a time was the new rule. I was not going to have one of these bags get hard in my garage while I waited to use it….
I got all set up and the first rows went in very easily. The I tool was working great and I mortared the front half of the joint and adjusted the angle with small rocks and brick parts.
It all seemed to go well. I got about 6 rows done and decided to let the mortar set and come back another day. Guess I thought it was going too well and it might screw up if I pushed too much.
It all went well and was hard the next day… so onward and upward. The Heatstop 50 mortar is really a good product; it held the bricks in almost any angle needed.
I soaked each brick for about 60 seconds before use and then let it drain off all the excess. This made the mortar stick well and not dry out. If you don’t get the excess water off then the mortar will want to slide off.
I had to wait about 3 days until I could get back at it. I was into the top of the dome… fun times. The neighbors thought I was making a bee hive.
The bricks needed to be cut more often, and in unique angles during this phase. But I was still using a chisel and hammer and was able to do it. The gaps in the back of the bricks would be filled with mortar later, so that was not a problem. I made the inner arch as I came to it…not too hard, I had a metal arch to guide me and the transitions to the dome were just not that bad. I was worried about that portion of the build so that was a welcome situation.
The top was closed the next day… not as pretty as many I had seen, but it went well. I had a piece of wood under the hole for support and just cut the bricks and wedged them in place.
And it was done!
Cool.
The front arch was made a little larger and it went in just as easy as the first.
After it all had set for a while, I filled in all the spaces. For a while I used a mortar tube. It was a rubber cone that you put mortar in and squeeze it like a cake decorator and it shoots the mortar into the spaces. That worked well and then I just troweled the rest in to cover the gaps and the brick ends, and left it to cure.
Now I am off to finish the chimney and start on the outside. I want to have a slate roof made of this stack of vintage roofing tiles I bought from someone in the historic district inWilmington. It will be looking cool when it’s done.
Stay tuned and see the next step
…. And it will not be delayed by any cold weather!
