Thanks to all who helped me here! My heater is fired up and rocketing! I have put pictures up in this blog article:

Thanks again to all who have helped out, I'm now constructing the bell...I have a technical question: I have scaled the core to a 175mm system as that is the available tube. But now my floor channel is 67mm wide. I can only get 70x30 or 60x30 tube, so should I go bigger, or smaller? or do I need to fabricate my own tube, which will be tricky....? Thanks guys!!!

I see what you mean, sounds good. My thinking is that maybe a steel plate (1 cm thick) will spall and fail and need replaced, but if those t-sections fail the collapse will be quite spectacular! Also, the firebricks I can get are rated to 900c which is maybe not as hot as the top of the bell, who knows. I think I might leave the oven out and just have a flat faceplate instead. If the plates heats up enough this winter, I'll cut a door and weld a box into the back. Thanks agin for the feedback!

Thanks for the input satamax, I had a feeling that the arlite slab was a bad route to go down....

And the oven won't heat enough.... What kind of temperature can I expect in that area? I'd be disappointed to make an oven and not eat any baked spuds.

Any images of how a composite top might look?
Some t section steel and then bricks laid dry on top with next later mortared onto them? I was thinking a thick steel plate that might last a few years.... Here they sell thick square plates that are bases for steel columns. I would corbel the bricks to close the bell top to 60x60cm, the biggest plate size.

I say it would be a bit like a bell in that it has extra volume, being of larger diameter and the exhaust would still be moving slowly compared to when it narrows at the vertical chimney. I bought the tubes today so I hope I'm right...

I did read the post to the end as recommended and was thoroughly entertained, I like the science fair interlude.

Is that ytong block wrapping the firebox? I was considering using it until I dug deep and spend a staggering quantity on ceramic fibreboard.

Here's a question.... To make a slab for the top instead of steel, can I cast one like someone said here with clay and sand and arlite? I can't find a refractory slab around here.... And, why arlite? Isn't it insulating, rather than accumulating,,? Also,  I'd hate to see it collapse and crush my fibreboard riser :-p

[img]Here is my almost finished design!!!
it's peterbergs sidewinder core with an oven / door insert

Can I make the pipe in the mass thicker to get the required ISA?? making it kind of like a bell?

thanks again, I've been away the last few days, so I didn't get a chance to check the boards. I Appreciate the input!

thanks, decision made, it'll be piped mass as I live continuosly in the house and it seems tecnically easier to build rather than sealing the bench.

a burning question: how long before I can fire up the stove with clay/sand mortar?
thanks again for your help

Hi again, I am almost ready to build, please have another look at this latest iteration and help me decide...does the bench benefit from being a bell, requiring sealing etc, or will a piped mass bench be just as good?


thanks again!
