folks i just started building my dome and it's turned into a nightmare. i built the whole thing only to have it collapse.
the refactory mortor i have is sh!thouse and doesn't seem to dry hard or stick to anything. i mixed it 50% with normal cement and sand and that seems to have improved things but i'm still not confident in this lastest arch. the problem is got to the point of putting in the key stone and it only went in about 1/2 way.
now should take out the key stone and cut it some more or will it do it's job here it is?
my other question is, is there a prefered method of pulling out the supports once the mortor is dry?
and finally, just how much mortor should each block need on it? the stuff is setting so fast on the block i can't even pour it down the cracks.
