metal roller



how could you roll it in both directions?





If you put it in a roller in this direction I think it would give you the curve you need.





see if you rolled it in your arrowed direction you'd get the first main curve just fine (i did that with my hands)...

the second curve goes in the direction of the contour lines i drew in the middle...it has to bend so the middle bulges towards you, and then follows the main radius also.

so you wouldnt be able to roll it in both directions.

heres another pic...


see how i have it bent that way, but its not touching on the top edge....its not touching on the bottom edge either. the tank has a small radius in it that bulges out the side slighty...thats why i need to bend it in two radius'
