Day 4 - Sunday!
It was a good day, starting off in a positive mood, with the feeling that we would prevail by afternoon. First step was the door arch, which was actually rather easy except for the cutting of the key brick. It really takes patience to get it right. It's helpful to make sure that all the mortar is spread thin on the arch bricks, so we wet and remixed our bucket of mortar before starting.
Furnace


Furnace This is the door bricked up with the little super hard to cut Tamax right over the arch. You might also notice the row of bricks jutting out to the right of the door. These are to deflect / shield the crown insulation on the right side from the flame. There is no insulation on the left side- that's where the door goes.


Furnace Furnace


This is the “meatball dam”, a row of IFB's that sits on top of the skew bricks. It holds in the frax and Green cast 19L that are going to cover the arch. Greencast 19L has been referred to as “meatball” at Spiral Arts for some years- if you've never seen hamburger helper, forget it.

This is the false work after it came out of the furnace. I got the question, “how'd you get that out?” What you may not realize is that the false work collapses. It's held together with little #8 finishing nails that have their heads cut off. The slats have holes that are just slightly larger than the nails. After you've built the arch you just pull out the stilts that hold it up and the whole thing just falls apart just like a Furnace


Well, I forgot to get a picture of the rest of the bricking on the front. I'll put that up tomorrow. I promise, we got all the brick work done except for the flue.
