I need to fashion tubs for the interior of the bed on our '37 Dodge P/U, but I want the tub edges to be radiused an inch or so. I can't find any commercially available tubs other than the ones with a square rolled & crimped edge.

Are there tubs available with a radiused edge, or does someone know of a commercial object (lightweight air tank, ???) than can be cut apart to form the tubs. I need around a 34" diameter and would prefer something fabbed from 16 ga crs.

I thought about rolling a piece of 2" dia tubing into a semicircle, then quartering it lengthwise and filling it with sheetmetal. But I'm sure I'd get too much distortion in it before I was done.

Thanks for any suggestions, Mark
