Making The Bourry Box Grate

I started with stainless steel pipe from the scrap metal yard. 1 1/2"  to 2" inside diameter pipe works best with standard firebrick.
Solid stainless bars would be better but that is a rare find. I filled these pipes with Lou cast 3000 and they will do just fine.
Bars are in and ready to go.

Capping

Finally we have started capping the arch. We made the mix from stuff we had laying about: fire clay, crushed soft brick, sand, old recycled castable and sawdust. We used portland at a rate of 1 part to 10 parts other material. 
We start with a layer of mix, then chicken wire and then another layer of mix.
Philip Wiggs and Hunter Smith smoothing the last coat of castable.
Hmm better be getting a roof over this thing soon.
