A six-metre offset cooker, built from a decommissioned pressure vessel

This is the big end of "no project is too big". A decommissioned pressure vessel came into the Queanbeyan workshop for a local company; what left was a commercial-grade offset cooker, cut open, re-plated, fitted with a fabricated burner manifold, expanded-mesh grate racks, internal heat baffles and an offset firebox on its own stand.

What the job involved

Nothing about a build like this comes off a shelf. The vessel had to be opened up along its length and re-plated, and every internal component (the burner manifold and its mounting fins, the grate racks, the curved end plates, the baffle that carries smoke the length of the chamber) was cut, formed and welded here. The offset firebox was fabricated separately and mounted on its own steel stand so the cooker sits at a workable height.

It is the same fabrication that goes into a stock crate or a tipper, just at a different scale. Which is the point: if it is steel and it is possible, we can build it.
