Flatten Plate?
I thought that I could bolt it to the table frame and pull it down flat. The table frame is 3" channel. No luck there. I've been told to heat one side with o/a. I can see how that works with I beams but I don't see how it would work with plate. (how would you heat one side of a plate?) I thought about putting the ends on blocks and driving over it with my Ford Ranger but I don't want to put a bend in the center and still have the warp to deal with. Also the pickup may not be heavy enough.

If it were me I would put it down on some flat concrete and drive over it.

to save me from a long drawn out answer, here is a link to the Miller website where this was discussed not too long ago. he tried what you are describing with the truck for weight and didn't have much luck, as you will read with some well placed heat you will be able to bring it back nicely.

Heat with O/A running heat stripes, from the convex side running 90 degrees to the axis of the bow.
This can also be done by running several arc welding beads in the same manner as O/A, then grind them flat. Do a little of either at first, allow it to cool, grind as needed. Then monitor progress and repeat until flat enough.

I have straightened things with an arc welder before.. weld a bead on the curved side in the middle.. when it cools it bends back... same concept as the OA but more accurate.
but then you ahve to grind off the weld.

I guess I would use a welder on the plate. Like Bucks drawing. Just remember the problem has to get worse before it gets better. It takes time!! Let it cool before adding more weld.
