 Re: Another Cracked Dome
Sorry about the crack neighbor.....
As a student of stone masonry, (anyone remember Ken Kern?)
your crack is very interesting....look very closely at the photograph and you'll notice that a lot of the brick joints below the crack (4 or 5?) seem to line up as well as the one over it.
This is a problem with stone or brickwork when too many of the vertical joints are allowed to line up...you're asking for a crack because of the weakened structure. One always has to be careful that the next upper stone or brick lines up over the center of the lower joint, ....as much as possible that is. One or two vertical joints lining up is okay but the more you allow to line up without a bridge, the more likely that's the location the crack will form.
Sorry it's not much help to you now Jim ...but might help other builders.
I also wonder how many crack free domes exist after using them.
Love your crack, it's character.
