Newbie homemade oven project...

You're lucky. Maybe vegetable oil is not so volatile. People think that because the drum is empty then they are safe, but not so.It only takes a tiny amount.

A CAUTION TO ANYONE wanting to repeat this design, if you use an oil drum then make sure you pressure wash the inside thoroughly with detergent before cutting with either an angle grinder or oxy torch. Many people, all over the world have died cutting drums from the resulting accident where volatile oils and oxygen mixed together inside the drum have ignited, creating a powerful explosion. This happened at my old school where a teacher directed a student to cut up some drums to make some cattle feeders. The teacher now has to live with the knowledge that this accident caused the death of one of his students. The same thing happened to a school friend of mine working alone at his farm.

Could happen. This one had vegetable oil in it, so I wasn't worried. I cut it with a 4 1/2" angle grinder and a cutoff wheel. Took about 15 minutes, and worked great with no issues.

Re: Newbie homemade oven project...

Poohbair,
I've seen ovens on the internet that have used drums, but I'm concerned about what was previously in the drum, whether the drum is galvanized, the paint, etc. I would not want to be around the fumes coming from burning a fire in this drum. If you're considering going this route, I'd suggest using the drum around which you can create a form from different materials.

On second thought, why don't you just download the Pompeii plans and use them? While I've laid tons of concrete blocks when I was a kid helping my brother build a barn and my father building a garage, that was decades ago. I've never laid a brick before and I'm well on my way now with my oven. There are hundreds of skilled folks on this forum to help you with that.

PBR does strange things to the thought process. Looking forward with interest on your build.

Only time will tell... my "plan" changes from moment to moment

There won't be anything you can do about it unless you start over at this point, so it is what it is.

What influences the design changes?
Is it new and better ideas or newly found a materials.?
I'm not adverse to changing my mind but I usually have a plan to start with
Regards dave

Well ... I started with a "plan" ... Started building, knowledge and materials have made the plan change as time goes .... Weather is a big factor now ....

Re: Newbie homemade oven project...

Well, that's a bit rich for an insulating mix...but it will work. I'm curious as to the performance of the bottle/perlcrete comb as an insulator. I suspect because of the slab, your floor will lose heat relatively quickly compared to the dome.

I'm not sure if it is that big a deal though.
