Default A little patience will

Go a long way in straightening a warped piece of steel. I was asked to straighten a bent work bench in the granite place. A worker had cut out the support braces on this bench to open it up like the other 4 benches they work on. However, the 2x2x 1/4” tubes on the top bowed up a 1/4” in the center of a 6’ bench, due to the welds on the bottom gussets, and angle iron frame to support the 2x4 wood pieces. They did not realize this until they put on a 5’ long Granite counter top and it cracked in half due to the bow.

I came in and said I can fix it with my torch.

Loaded up my torches the other night and proceeded to heat certain spots on the tube and got the tubes straight within 1/32” stretching a string across the tube. The only force used was the torch, and some water to help cool it back down, and time.

Thanks to Clive years ago for sending me some info on learning how steel will pull and shrink due to welding and heating.

Very well done!!! I used a rose bud to straighten out a portable truck scale the same way once upon a time.

Looks like you save the next counter top that will go on that table
I bet when they set it on there and it snapped in half it gave someone a sick to their stomach feeling I know it would have gave me a sick feeling...

Yup, very nice work it takes a lot of patience and resisting the urge to force the material. I watched the Old-timers in the fab shop straighten the top flange for a fabricated beam for Bethlehem steel one time. It was 1-1/2"? X 60Ft. Basically the burners didn't stitch cut it enough to prevent major lateral warpage. So they had to bring it close to straight before they fit it up. They worked for 2 days with one of those 3ft. rosebuds with a head the size of a coke can. Heat and measure heat and eyeball over and over until they were satisfied. Quite the process but , it ain't like you go oops and shit can a chunk of steel that big. Watching them work a section and fit it to the web then keep working it till they tamed it end to end was impressive.
