Next thing you can do, is cut out a small wedge. Bevel the cut with a grinder, and weld up the cut.
A port-a-band works great for this.

Ya, would have done that already had it not have been for learning of flame straightening here. I've only got a couple hundred bucks into it so far so not the end of the world to sell it and start over. I'm sure there will be someone locally that will be happy enough just having one and willing to accept the weld-induced twist

That's the spirit! Long ago I would have gone to great pains to rectify, hide or redo it. Nowadays I'll point out my screwup(s), have a good laugh and get on with life.
You did a fine job and you should keep,it but if you're like me you'll prob redo it some day with a few newly rethought refinements.
Thanks for pics and posting,CDN Farm Boy.

When I bought this grapple, the cutting edge had quite bow in it. After revamping it, and lightening it up I heat shrank the lip. Couldn't get all the bow out. Thought about building a strong back and using a hydraulic jack to remove the rest of the bow. But then thought, Oh I'll just bend it again anyway.

I am by far no expert on this. Been watching the last few days and just keeping my keyboard silent. I have had limited success straighting warps. My method varies according to the bow and I cant really tell for the pics how much bow or where its at. My best success is heating thin lines across from where the welds are, If the round bar is welded vertical to the angle. I go straight across to the back side part of the angle and heat a thin red hot line all the way across, then quince with cold water. If that doesnt work, i move over the thickness of the previous red line and heat another line, again quince with cold water. My way of thinking is the welded area is what has drawn the metal on one side of the piece of steel. heat skrinking the back side should pull it back straight.
