[TheForge] Fw: Circle Roller

[Peter Fels & Phoebe Palmer]

The minimalist approach is to weld 2 parallel pipes or bars to a fixed 
plate, next to one another. The work is extended at right angles between 
them and bent a tiddle, extended a bit more and bent..and so on. The 
smaller the extended increments, the smoother the ring. Works for sheet too.
