From Hanno:

"Contrary to popular belief, only the cross members were made of hardwood, the planking was softwood so you would be good using pine. I'll look up the thread with that info later."

For Canadian (and British?) wood trays, but doesn't apply in Australia. The trays were a local pattern and made of hardwood.

Jacques: or if a big spot welder is not available (as it isn't for many of us I suspect), use the drill-and-weld method. Drill small holes in one side of the pair to be welded, then weld through the hole to the undrilled-other half. With small holes, 'dabbing' the arc and grinding off, it leaves a neat 'spot'.
