Default Re: mortar gap

Quote:
So, does one place the inside edge brick to brick and then use a shim (wooden or a small brick chip?) to get the desired angle and mortar it in?
You can do this, but the mortar forms a pretty self supporting base for the brick, hence the multitude of brick positioning jigs (indispensable tool)

The smaller the inside joint the larger the outside joint. Aren't these large outside joints a problem?
No.

Is this why people add a finishing layer of mortar around the outside of the dome?
Sometimes people parge the outside of the dome with a layer of refractory mortar to get a little more thermal mass. It's by no means necessary.
