My late father built this many years ago using design ideas from a couple of published projects.
It's stand-alone mounted to its own stand and on locking casters for portability.
It can bend metal up to just over 30 inches wide. As shown it stands about 4 feet high. The base is 39.5 x 34 inches. I'm guessing the whole thing weighs about 80 pounds.
I'm moving and need to downsize so I hope someone else can make good use of it.
