Bending 3mm metal puzzle
An aluminium saucepan was dropped on the kitchen floor and now the lid will
not fit on, due to a fairly small flattening of one side. The saucepan is 16cm in diameter and the aluminium is 3 mm thick. My thumbs are just not strong enought to push the side out enough for the lid to fit on. Cannot think of a way to get a good leverage on it to re-shape it, without damaging the non stick coating on the inside of the saucepan. Grateful for any suggestion. Thanks. |

Lining the inside with 3mm polyethylene packing foam / laminate floor underlay avoids scratching, but crushes well when clamped. |

Draw around the pan, rotate it 90deg about its centre and draw around again. If the two drawn lines stay ontop of each other excpet where the "flat" is then the pan is still circular. If it's now oval the flat will be on the narrow oval dimension. Try pushing(*) on the wider oval dimension ie across the side at 90 deg to where the flat is. (*) Pushing may mean *gently* standing on the edge of the pan. Use bits of scrap wood to protect the pan and the floor. -- Cheers Dave. |

Might work to just grind off some of the edge of the cover. Can't take much. |

I've used a rubber mallet and/or a broomstick on dents like that. Support the edges where the flat starts and push out on the center of the flat area. The flat comes out pretty easily, so take care.

Thanks. I find an adjustable spanner often makes a good lever in such cases. Make sure the jaws are clean, smooth and parallel and adjust to give a firm grip on the work. In your case, I would put a couple of layers of newspaper between the jaws and the pan surface, to avoid scratching. bits of leather would work as padding also. a rubber mallet might come in handy... -- http://www.skepticalscience.com/ http://stopbeck.com|www.snuhwolf.9f.com|www.eyeonpalin.org _____ ____ ____ __ /\_/\ __ _ ______ _____ / __/ |/ / / / / // // . . \\ \ |\ | / __ \ \ \ __\ _\ \/ / /_/ / _ / \ / \ \| \| \ \_\ \ \__\ _\ /___/_/|_/\____/_//_/ \_@_/ \__|\__|\____/\____\_\ |

I saw a guy on TV once, on a deep cable science channell. He rolled up an aluminum pan like a tortilla, with his hands. Then he bent a 12" Crescent wrench to a 90 deg angle. Just do that. -Zz |

Put a piece of large diameter pipe in the vice. Rest the inside of the pan on this and work the metal by hammering the outside of the pan. Straightforward job. All of the suggestions which center around or include hammering are likely to fail, since the OP state he has a non-stick surface he does not want to damage. I would recommend a rolling action. Do a bit of research on paintless dent removal and get an idea how to restore a surface. Do not start from the deepest part of the dent - regardless of what's been said here... May just have to cut the lid to suit then the coating won't get damaged. |

I've done this myself. :) The dent sounds small enough to grab it with a large vice-grip or Channel-lock and bend it back out till the lid fits. Use some scrap wood ( I often use popsicle sticks) or something to protect the surfaces. You could also cut out a wood disc section of the same diameter with your jigsaw and clamp that into your bench vice, and then gently hammer the edge against this to restore it. You could put vinyl tape or leather over the wood and the hammer head for protection. The harder you have to hit, the more protection you need. |

Does it really matter if you damage the non stick coating at the top of the pan (other than for cosmetic reasons)? They're not made to be used full. |

IME the non stick coating last about two cooks anyway. |

That's a pretty hefty pan, which would imply a fairly hefty price and thus worth an attempt at repair. You could always take it to the local panel shop and get them to give it a nudge either hammer or porta power. |

Can you make a jack that will allow you to push out the flat spot from the inside? Use wooden blocks with an approximately correct curve to protect the inner non-stick surfaces. |

Bearing in mind that the OP is heavily cross-posted and that "john thompson" hasn't yet returned to this thread or the cross-posted strimmer or baseball bat threads either and I could be talking to myself here, my chosen method would be to drop the lid onto the kitchen floor from the same height at the same angle as the saucepan and try to knock a flattening into that too. If it's good enough for teapot lids to have a flat on the circumference then I reckon it's good enough for teflon-coated 3mm thick ally pans too. Nick |
