Plinth\Worktop

[davadvice]

Hello,

i'm looking to build a wood fired oven and would like some advise on my initial design.

My plan was to make a Worktop out of 100mm*100mm timbers and use some scafolding planks as part of the worktop not housing the oven.

The plan would be to have a 2m long worktop with the legs placed 200mm in from the edges and the oven housed in the center 1m in from each edge to the center. The centre of the worktop will be reinforced from front to rear again with 100mm timbers and a cement(of type i'm unsure, thermal layer perhaps) form to hold the base of the oven.

would someone advise if the 100mm timber will be able to hold a pompeii oven around 1mx1m in width?


I have some rough drawings I'll post when I'm at home

thanks
David

Hi there

I have begun my own build with a similar base construction.
I am not making work tops though , I have made a framework with 4x3 timbers stacked on top of each other interlocking on the corners. I have stacked up 11 timbers high , I now have my concrete base done ready to
Start construction of my dome and it's all solid.
I was told it's not adequate enough for a 10" concrete slab but I thaught differently , so I say go for it.
My timber frame is 900 square , supporting my concrete slab 1100 x 1200

G'day
My main experience with a wood based oven stand was one that was built on a hardwood brick pallet. A pretty smart idea really as a brick pallet is designed to carry more bricks than on oven and designed to be moved by forklift.
It had a piece of 15 mm compressed cement sheet on top then a 100 mm of perlite cement on that. The oven was moved onto a trailer by 6 strong men using timbers through the pallet and was towed 1000 km South . I lost track of the builder would love to know how it had survived.
Myself faced with using 100 mm timber and painter planks.
Those painters planks would get joist support underneath at not less than 300 mm. Or I would use the compressed cement sheet to spread the load.
Legs . Not just 4, just one at each corner, but rather more to spread out the load.
Cross bracing. A big one. It doesn't have to be 100 mm thick but you have to cross brace the whole stand. Bolt the timber through with bolts at least 2 at every joint .
Finally if at all possible house all the joints rather than just doing a flat joint for added strength.
