Newbie homemade oven project...

... it was best put to me by a fellow 4x4 enthusiast...

"You my friend are really a horrible mason"




Seems to be about dry. Hoping to get some insulation on it next week.

Re: Newbie homemade oven project...

Did a little more work today, then it rained.

Built a small fire in it to heat the oven up a touch to help it dry as the weather is cold and wet.

Added a few more bricks, and more refractory to the top of the barrel.

Despite the fact that today was my 17 year wedding anniversary, I got a lot of work done!

Dry-set, on sand or fireclay/sand mix.

Re: Newbie homemade oven project...

Do you guys use mortar / thinset to "set" your firebricks on the base, or just let them "float" and let the weight of the oven keep them in place?? I was thinking I could just let them "float"

Not sure.. maybe ~2-3" thick, and then the Rock Wool is 3" thick. Planning on building a "box" around the oven with concrete board, and will add loose Perlite on top of the Rock Wool.

3" would be good, with a couple layers of reinforcement. Looking forward to pics.

That's good, the refractory will break bond immediately, so reinforcement is crucial. How thick are you planning?

To answer your question...refractory first, then insulation.

Re: Newbie homemade oven project...

I was planning on putting mesh wire on the barrel for the refractory to stick to... this way if it cracks, the wire should hold it on to the barrel.

Re: Newbie homemade oven project...

The refractory layer will need reinforcement, or it will break apart from the steel thermal cycle.

Re: Newbie homemade oven project...

Hoping to get to work on this more this weekend.

I am going to be using Rock Wool for my insulation.... should I put a layer of home mix refractory directly on the barrel, and then insulation over that, or insulation right on the barrel, and refractory over that?
