My Build 42" oven GT

More progress

I finished the outter arch of the vent area in about an hour today.
I hope to have the vent and flue liner done within a week. Keep running out of daylight.

Re: My Build 42" oven GT

I plan on building the vent area and arch from the fire brick and then use a row of insulating brick prior to the clay flue liner.
Right now I am starting at about a 22" wide x 8" ( inside dimensions)deep gathering area for the vent. I am going to take this up above the inner arch a few brick before the thermal break using the insulating brick. At this point I hope to have the opening 8" x 8" to match the flue pipe.
I am wondering if I should go higher with the larger area prior to closing it in to 8"x8"?

- Nice job. How is the arch and vent going to go?

Re: My Build 42" oven GT

Finally done with the dome and ready to start the outer arch and flue entrance.
The inside dome looks pretty cool.

Re: My Build 42" oven GT

oops, I forgot about the 3/4" wood on the bottom.
I guess my dome interior height would be around 22".
It should not make that much difference.

Re: My Build 42" oven GT

It will all work out fine. I did not adjust for the size of the wood below my ID tool that was 3/8". I made an adjustment about the 10th chain and all worked out good!

Re: My Build 42" oven GT

According to my indispensible tool, the dome height is right at 21 1/4".
When I set my soldier course, I did not use the tool and it was a little over the 21" half way mark so I had to go with it the whole way up, If the top chains are sliding in a little on me it may end up closer to 21". The next row will be almost verticle with sharp angles.
Temps in the 40-60's all week so I should have nice weather to work.
Thanks to everyone on this sight for all the valuable help.

Re: My Build 42" oven GT

Dome is looking great. You'll be making a few really steep cuts now and then your keystone. Getting really close now. What's your final dome height looking
like?

Re: My Build 42" oven GT

Looks like your close. Just one or 2 more till the keystone. Looks great.

Chain 11 finished.

Finished chain 11 with a dozen tapered and wedge cut bricks.
A lot tougher going with the smaller opening.
I am left with a 10" hole on top and the next course is almost completely verticle.

Re: My Build 42" oven GT

Completed chain 10 today using all tapered brick. I only have a 14" diameter opening at the top, filling in at about 5" per chain now, I have two more chains and the last brick. I am going to cut smaller brick with a taper for the last few chains.
Saturday and Sundays cold weather was tougher to work in, I used the small ceramic heater just inside the arch to keep my hands warm, the thermostat actually shut it off a few times. It helped the bricks stay in place as the mortar stiffened up with the little bit of warmth.

Re: My Build 42" oven GT

Thats the plan then, it takes me less than an hour to get a chain done now.
I spend more time cutting and cleaning up.

Re: My Build 42" oven GT

You can do it all the way. Though I did use piece of plywood on top of stack of bricks for the last chain and the keystone.

Re: My Build 42" oven GT

The pond has lots of fish, I catch and release them for fun. I really wish it was double that size.
Today I finished the 9th chain using a combination of halves and tapered halves. I cut an angled taper to help reduce the triangle mortar joints that start to appear on the inside. It helped some.
Of course it was raining again. I actually started the morning cutting the bricks while it was snowing and raining.
How many more can I do using the sticks? All the way?
