Aussie Mobile base oven
 
Hi all have gathered up enough steel and made my mobile base for my oven.
ive decided on 800mm diameter igloo,going the cheapskate way using aussie pressed reds(bricks)following Russell Jeavons Book.
Will be using 100mm vermecrete slab topped with 50mm thick fire bricks.
i will post some picks when i take some.

Cheers Peter

Hi Peter! Looks great. My only concern is the stress on those wheels. Are they rated to take a thousand kilos? Also, the small diameter of the wheels might make it tricky to maneuver over bumps or cracks in the driveway or garage.

Remember, this oven is going to weigh over a half ton.

Good luck with your build... Can't wait to see more progress!

I would suggest heavy cast iron casters like these:

MSC Item Detail

Light stamped wheels, particularly swivel mount ones, could collapse, with the potential for disaster. If surface protection is a consideration, you can get plastic covered wheels, but they still should be heavy cast wheels.

You might also consider some diagonal bracing for your stand.

Since you are going the "cheapskate way" I assume you are not above scrounging and recycling. Here in the US one can find very very strong swiveling casters with zerk fitting and needle bearing rollers rated for lots of weight if one knows where to look. If you have a postal distribution center (main post ofice where mail is collected and trans-shipped.... most big cities have them). There they use "trains" of large bins on casters to move the mail. The cars are quite big and can hold many thousands of pounds of mail. The casters they use are as I describe, that's where I found "used" ones for $10.00 US each. One would assume in AU they use a similar system. I have had a 2000 lb plus Intertype machine on a set for moving and they work wonderfully.

Here's a photo of one such caster on a paper storage unit. The tyres are urathane and sunk into the standing cushion in this photo. Casters are 5" in diameter. So they are out there, if you have the time to scrounge.

For those in the US and Canada I thought it might be worthwhile to post a link to a useful site for those of us who are not above scrounging and recycling.

I understand such sites exist in other countries as well so a search on Google might prove useful.

Here's the link:

Thanks for the comments guys,the wheels are rated at 180kg approx each they just look small in the photos (wheels 5"dia) we have them at work bolted to large sand conveyors without any problems.I am cosidering fitting some more if i can get them for better load distribution.And yes i have enough tube left to add a extra brace may look into it tommorow after work as was raining in Melbourne tonight.Cheers Peter

G"day lads i have checked the wheels they are 6" not 5 as i thought,i have braced 3 sides leaving the front open for wood storage,added 4 more wheels,
also added a brace under the centre.it has more steel in it than my 500kg metal lathe stand.If i find the rubber no good you can get the above mentioned wheels at a good price,even the solid plastic 6" hold 300kg each!
damn good plastic i think.will upload a pick when i can.cheers have have a good weekend building or having pizza and beer.
