For those that haven't tried this it works and it's easy. Welded a diagonal support and the leg bent at the weld ,not surprising. To straighten it out just ran a few weld beads on the other side of the tube and cooled it off with a wet rag. Bam it's straight again. The warp on this part wasn't that bad but this method can move material alot. Just thought I would share this with all you folks out there.

If you hv a crack open up on large part & cant get it back together. Take thick piece of metal heat it to dull red, lay over crack weld on both sides, cool with air gun. Will pull together. Weld crack. Then cut off. If large crack can use more than one. <br />
There are companies that specialize in straightening large I beams like bridges with torches & cooling pretty awesome. <br />

You can also straighten or pull metal by peening with hammer. The old timers were masters at straightening cast iron by peening. Getting to be lost art.
