Got this at an industrial auction business folding up. It's real sturdy to say the least. Lol

Got this table a few weeks ago at an industrial contractor going out of business auction. It's REAL sturdy to say the least. Lol <img src="http://www.tractorbynet.com/forums/files/welding/405055-welding-table-build-image-3917438099-jpg"/>

Congrats! Nice purchase.
Just to clarify. This isn't the HF one on sale, right? Terry

Very nice! I wonder what that weighs? I would love to come across a find like that!

Wow two responses in 1 min! I didn't mean to post it here but guess it doesn't matter. Lots of interest. It's around 3,000 lbs to 4,000 lbs I think. My Kubota can barely pick up one end. 12" or 14" I beams.

Without being there it's hard to walk you through this.
Try this, heat the red areas first. Start in the center, heat the wedge. Top side and bottom on the leg, then heat a line down the other leg of the angle. Take a spray bottle of water to cool, or your garden hose. Cool the first area stone cold to the naked hand. Then move to the next wedge, and do the same thing. Each time cool that area stone cold to the naked hand.

If you still don't get the results you want heat the green areas next, doing it the same way. If this doesn't fix it. Heat the blue areas next, the same way.


If this doesn't fix it, you'll have to live with it!

I would try warming up the same spots only over a slightly larger area.
If that doesn't work you should have done it the other way.

Funny guy....lol

Yup, certainly a bit tough over the computer. If we were a few hours drive apart rather than a few days, I'd be throwing it in the back of the truck and happily paying you to walk me thru this in person. I guess this will have to do

I'll try that and see what happens. Thanks

You want to heat quick and cool quick use a rosebud if possible and garden hose.

Thanks.
Rosebud is something I don't have, yet. And garden hose isn't an option until April, it's -20° here and a howling wind right now.

For now, I took SA's last suggestion. I was able to get it close enough to make it work. Still crooked but better. Next summer I'll likely just sell this one cheap and build another with more jig/brace to ensure that it stays straight and square.


Thanks for all the help.

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.
