[TheForge] Straightening heavy Grill

[Peter Fels And Phoebe Palmer]

Assuming it is very annealed, you can probably use a chunk of RR 
rail for a dolly and a 4# hammer and work it back to flat.
For major warpage, some chain and a cheapie porta-power will do 
wonders. Bring along a chunk of plate for an anvil and a sledge.
A properly sized set of spud hickeys or forks would do it too.
I once used a hydraulic jack under the axle of a big truck to 
push the high spots flat to the ground..available tools.
I also suggest lots of beer....lots...pf
