Ash-Kennard Posted January 20, 2006 Report Share Posted January 20, 2006 i was just thinking in school about something I saw at the weekend, a dent repairer for cars in fareham, it looked like he was just buffing it out but maybe he was using some sort of sucktion device for popping them out. So I am now wondering if they could "pop" out dents on our frames? reasons it may not work:-metal too hard to 'pop' outcan't get the tool into the frame with out cutting it (if its buffered out)the sucker can't get a grip on the framei was just pondering this earlier, it may not work but if it does it could work out to be very helpful indeed Quote Link to comment Share on other sites More sharing options...
Tomm Posted January 20, 2006 Report Share Posted January 20, 2006 A dent in the side of a car isn't structural though. The only reason to get a dent out of a trials bike would be if it was going to make the frame stronger again, which it won't. And I am not convinced by people who say dents lead to cracks etc anyway. Just leave them. P.S. it wouldn't work anyway. Quote Link to comment Share on other sites More sharing options...
Ash-Kennard Posted January 20, 2006 Author Report Share Posted January 20, 2006 fair enough, if it won't work then don't worry. just close this then Quote Link to comment Share on other sites More sharing options...
Matt_Tupman Posted January 20, 2006 Report Share Posted January 20, 2006 On most frames the material would be to thick Quote Link to comment Share on other sites More sharing options...
Simon Posted January 20, 2006 Report Share Posted January 20, 2006 And I am not convinced by people who say dents lead to cracks etc anyway.Want a look at my frame? Dented last year on big london ride, the one where the kotMS2promo video was filmed, with Staples.Noticed the middle of December, stemming litterely from the center of the dent, a nice big crack. Most dent's on cars are pushed out anyway, and as you've said, thats impossible. Quote Link to comment Share on other sites More sharing options...
Synergy Posted January 20, 2006 Report Share Posted January 20, 2006 sounds stupid but could you not heat the metal soo much it moved back out of the dent? Quote Link to comment Share on other sites More sharing options...
Dan6061 Posted January 20, 2006 Report Share Posted January 20, 2006 sounds stupid but could you not heat the metal soo much it moved back out of the dent? Wouldn't doing that feck up all the heat treating and stuff that was done to the frame in manufacturing? Quote Link to comment Share on other sites More sharing options...
Guest Posted January 20, 2006 Report Share Posted January 20, 2006 Wouldn't doing that feck up all the heat treating and stuff that was done to the frame in manufacturing?Correctemondo!!!!If its steel you might be able to sort it out but if you get a dent you are best to leave it, pulling the metal back again will only weaken it again.Aluminium has a fairly low melting point. The reason you can't reweled alumunium if its snapped or cracked is because the heat of the welding will soften the surrounding material. The bike may be welded solidly, but the internal structure or the metal will be such that it can crack/snap again easily around the weld, thats provided the new weld holds up....

adamtrials Posted January 20, 2006 Report Share Posted January 20, 2006 I seem to remember something about pop riveting the frame or something similar, then using a special tool to pull the dent out, then smoothing over where the rivet was.Im sure ive heard of someone doing this to there frame.

Ash-Kennard Posted January 20, 2006 Author Report Share Posted January 20, 2006 depends on the bike.muwahahaha, i have steel, leeson all the way. Quote Link to comment Share on other sites More sharing options...
mat hudson Posted January 20, 2006 Report Share Posted January 20, 2006 i let my curtis fall against the corner of a wall yesterday, no dent. scared me though, that'll teach me for playing with my camera Quote Link to comment Share on other sites More sharing options...
dave33 Posted January 20, 2006 Report Share Posted January 20, 2006 wall thickness is from normaly 1-3mm depending on what frame really Quote Link to comment Share on other sites More sharing options...
2sixstreet Posted January 21, 2006 Report Share Posted January 21, 2006 I have to agree and disagree with comments above. Talking purely aluminium. A sizeable dent WILL cause stress raisers and eventually become a crack and a trashed frame. If the dent can be popped/squeezed out then so much the better. From experience a mate of mine dented his Cannondale XC frame which turned into a broken down tube. I dented the top tube on a Schwinn and had it popped out. No problem to date.Car panels are more cosmetic than structural.Aluminium will work harden after a couple of 'cycles' and therefore have limited 'dent' life.

BI-KING Posted January 21, 2006 Report Share Posted January 21, 2006 Motorbike shops have the tool for poping the dents out of motorcross exhausts, think they just blow air into them till they pop out . Dunno if it will work on a frame though Quote Link to comment Share on other sites More sharing options...
