Re: 42" build in Virginia

OK, I hit it hard today. Just finished up. I was able to close off my dome using a exercise ball for support. A little trickie to say the least.
Who came up with the idea to stand on an exercise ball to lay your brick?



I hit the wall with only a small break, but wanted to tackle laying out my new arch like deeyooah suggested. I get some pics and hopefully get some advise.

thanks, fabby

Hi Flabby,

Well done.

Re: 42" build in Virginia

Thanks!!!!

This is more harder than I ever thought it would be.

I removed more of the arch bricks and laid out an arch for the opening.
Not sure how to tie into the vent.
Help.............and then send more beer.


Do the joints at the inside of the arch touch, or are they 3/8" ?

They should touch on the inside. If you can put even a partial taper on them, they won't be able to fall if the mortar bond fails (they'll be wedged in place, brick-on-brick).

You made it past the hard part! Taking out the galv steel and hung in there you deserve a Guiness.

Mortar bond fail is no big deal, you would need every last crumb of mortar from all the joints to fall out of an arch for it to fail.
The biggest killer of arches is lack of buttressing due to the arch wanting to lay flat and pushing out the side walls.

They actually build flat arches and with proper buttressing they stay where they were built..

Re: 42" build in Virginia

If the two joints on either side of a (straight) brick fail, and the rest of the arch remains bonded to the dome, the brick can fall. There's more than one post on this forum lamenting that fact.

The straight brick cannot fall out due to the tapered joints, its just impossible.

Post a pic anyone if its happened.

Re: 42" build in Virginia

Fabby - on your arch, it looks good - but I think you want the length of the bricks on the end to be staggered so that you can tie in the front part of your arch.

Re: 42" build in Virginia

I was trying to visualize how to tie in the vent and front arch. I have some half bricks that I was planning to notch the arch bricks to span the sides. Not sure if I can do this or not.



Does that seem like it will work?

Re: 42" build in Virginia

I was planning on using some terra cota rectanglular vents to make a chimney. 9"x 12" is what they stock. Is that too big? Will terra cota hold up OK and handle the temps?
