I tried the "wringer roller" approach and found it to be tedious, 
almost impossible to control the curling and mildly costly..

I made my own wringer first and had poor results, the rollers NEED to 
be exactly parallel tangentally in both X and Y positions. The next 
effort was done at work in the metal shop ( they have a real roller 
there) and you need to have the tube as straight as possible and as 
close to perpendicular to the rollers to avoid the "curl" effect.

All I have now is 2 rolls of wavy flattened Cu tubing rolled up in 
the corner of the shop....
