By the way, I was just into Lowes hardware store this day. I was in
search of some "Sono Tube" or "Quick Tube." It is a cardboard tube,
very sturdy. They had lengths of ~4-6 ft. The largest diameter they
had was 12" (they had 8,10,12 inch dia. in stock.) I needed 18" or
larger as I was going to use it for construction of a "cat tree."

But, anyway, sounds like excellent material for a "former."
