I met the seller of the 30" "18 gauge" slip roll today. I bought the machine
because it was a good price and I'm positive I can sell it for that, but I
don't quite understand it yet.

It isn't a slip roll! Meaning, none of the rolls come loose so you can slip
a rolled tube off. I'm sure with sheet metal thin enough, you can roll it
to a closed loop and then open the loop enough to get it off the roll, but
boy that seems klunky to me.

Anyone seen one like this? Am I off base here?
