Mountainside,

Take a look at the jig I built in "my brick cutting tool" "http://www.fornobravo.com/forum/f28/my-brick-cutting-tool-12478.html". I think you could make a bunch of throw away jigs by cutting wood blocks to mirror the front to back course angle and add a bit of plywood for stability. You'd still have to set the course radius by estimation or building an extension to the rolling cutting bed and wood block jig.

As I've said before, people understand things in different ways, brain wiring etc.. I hope this helps..

Chris

Les,
Duh! Confusion was all mine. With the top-of-the-dome bricks being so small, would you consider pre-building a keystone 'plug' on the workbench and drop it in?

Thanks, yes, as you get higher, the cuts get ridiculous. My circle shape is far from it- more oval- so the consistency of the cuts becomes irrelevant and I needed to custom cut evey brick- nightmare. Just glad this is the last row before putting in the Keystone. Les, did you even cut the faces of your bricks?

I first cut every brick in half. The cut surface is exposed to the inside of the oven. It just looked cleaner to go that route because the outside edges of my brick were "ugly".

I layed 19 wedges on my last course this afternoon and almost every wedge had varying trapezoid angles.....anywhere from 4 to 10 degrees on my compound miter saw and it was a pain in the butt going back and forth, cutting a degree or two either on one side or both sides of each wedge.
Now I'm left with a nice round 6.5" diameter dometop opening. I don't want to add any additional height to the dome so I will cap this opening with 3 fitted pieces which will fit flat across the top.

Congrats George!

Although you have the keystones to fit and place you're a hour or so away from having the dome complete, cleaning and curing aside.

Literally - I made so many trips up and down I had sore muscles down there that I didn't even know I had.

Thanks Chris! I'm capping my dome today.
