How to build a shed sized giant oven and what kind of costs are we looking at?

[Maury]

I know this sounds a little crazy but this is being done as we're going to attempt a world record in a few months and will only be for one use so we don't need any gadgets and it can be as basic as possible as long as it's clean and does the job.

[Maury]

It will be used to cook meat weighing 156.8 kilograms (346 lb) so could be smaller then an average shed

You could fabricate one out of steel I suppose. What type of fuel are you going to use to heat the oven?

Perhaps a local pottery may be able to help.

[Maury]

Thanks for the answers, currust I've never built anything so am all ears for advice, could coal be used? How much would insulating bricks or materials be?
D97 I've already thought about that but not sure whether health and safety would allow it as the food cooked in my giant oven will be for human consumption.

[Frank97]

Good point.

Have you thought of getting a hog-roast company in to cook it for you. They have huge rottiseries(sp) to roast full-size pigs & they will also conform to hygeine regulations.

Can you not spit roast over an open fire ?

[Maury]

I like the hogroast spit idea but I'm not sure that guinness world records will award the record to us if we've had help.
Canary it will be a whole Ostrich weighing roughly 156.8 kilograms (346 lb)

Redhelen thanks but we need an oven as we're doing a feast and I doubt the stones will cook a bird that large though I wouldn't mind trying this method with a regular sized bird.

Maury, a cheap way would be to go to a scrapyard and see if you can get an old domestic heating oil tank. No matter if it has a few holes. Cut an access with an angle grinder. You'll have to scrub the inside clean.
To heat it, you could sit it over a bonfire, or rent a couple of industrial space heaters that run on propane. You know, the ones that look like a jet engine.

maury -where in the UK are you? - we are a firm of stonemason builders and among other things build outdoor wood fired ovens - it would be a challenge but for charity we would do it for free. You would need bricks ( not fire bricks as ordinary bricks withstand very high temperatures) and you need a good supply of dry logs - think of a huge pizza oven.
