Wow, Les, that's so terrific!
I don't know how you'll be able to stand lighting a fire in something so perfect and pristine ...are you going to make us all wait for it till Frances gets back??!!
Thanks everyone for the complements - appreciate it. I was going to fire it up full throttle after I got back from this weekend, now I'm thinking I should get the flue on in case some mods are required. I also want to see how it draws, probably should wait until it's really ready for fire. I'm not too concerned about a cure time. The mortar is pretty thin and the temps have been in the mid 90's, humidity around 8%. And we all know cracks happen.
Everybody in the US have a safe 4th - everyone else, be safe.
OK - on to the next level. These are a couple of pic's of the rough cut of the flue. I tried to take one shooting up-wards but the sun would not let me do that I will see how it draws and go higher and narrower if necessary.
David - how in the hell did you cut these. This stuff is incredibly hard. I got through it, but my grinding blade took a hit. If I have to go higher, I'm taking it to my neighbor and have him rip it on his 14 inch saw.
My "cure Fire" pegged my thermometer, 950+ degrees. This morning I checked the dome temp - it was 262 degrees, no door, no insulation - awesome! The cracks seem to be minimal, so I would say that the approach of not using mortar inside the dome is a success. I may not even put another coat of mortar on like I was planning. I will fire it up again today and see if any of the cracks get bigger, if not, I'm wrapping this puppy up!
It took a while for the soot to burn off, but when it does, it is VERY cool to watch. I have some video that I will post (after I figure out Youtube). These pictures are taken the morning after - the one of the cracks shows the worse one, I don't think it's too bad.
I may not even put another coat of mortar on like I was planning.
I wouldn't bother, either. You have plenty of thermal mass and it'll just crack from thermal movement like the first layer. I think you are good to go! That thing is absolutely awesome!
