I've been asked to make some sheet metal wheel barrow trays that need curved/rolled bottoms, in leiu of straight sharp folds.
The reason I've been asked to make them, is that a Kelso barrow only lasts about 3 months, and the tray's worn out, the frames last about 6 months as do the bearings in the wheels.
To make these, I'm looking at making a press similar to a garage press, but 1200 wide inside, it will have 2 X 20 tonne jacks supplying the downward pressure. Does anyone have a press similar in size, that would be able to give me the material size for the uprights, and cross members both top jack holding and bottom rails that are pressed against. Was thinking something like 150 X 75 Channel forming an I, for the top rail, and the same for the bottom rails, with 100 X 100 X 5mm posts for the uprights, sheet will be 2 mm thick.
I know that no-one will say that the material will be OK, which is why I'm asking if anyone has an existing purchased unit to basically work from.
