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
Robbie Mendelssohn wrote: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!!!
