fenders/mud guards, hammers, and pincers
I have learned that with a ball hammer, the thin side
of a warrington hammer, and a hard surface, it is possible to hit damaged fenders/mud guards (?) into near-perfect alignment once again. The tricky part is not getting them straight which isn't that difficult, but rather to do it without leaving a mark where you hit it. Perhaps a combined rubber + ball + warrington hammer would be optimal for this? Anyway, what I've been unable to solve satisfactorily are the slopes on the below left-and-right edges of the fenders. This is where there is sometimes a wire to carry electricity to the rear light from the front wheel, if there is/has been either an external dynamo or a front wheel dynamo hub. The wire is easy enough to pull off but often the fender slope is damaged at points - it is folded, like the letter "v". Did anyone came up with an intelligent solution how to get those straight? I have hade some success with a pair of pincers but it doesn't always work. -- underground experts united http://user.it.uu.se/~embe8573 |

Dents across the main sections are very repairable as you found using well known auto body panel techniques and tools such as smooth hammers and dollies: http://image.hotrod.com/f/56190817+c...-dolly-set.jpg or just about any heavy smooth thing (such as a second smooth faced hammer) Care should be taken not to overwork the piece which can expand and deform the material also known as 'oilcan effect'. I find removing the mudguard from the bicycle makes this job much quicker overall. YMMV. I don't have a good snappy answer for turned edges. Those are formed on a English Wheel or something like one: https://www.youtube.com/watch?v=2v4Cbkm2_ug -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

But I think what I have is sufficient so I'll get it only when I strike it big... I find removing the mudguard from the bicycle makes this job much quicker overall. YMMV. No, this is what I always do and I didn't even think this could be done with the mudguard on the bike. So much easier to clean, examine, and hit (especially against something) it if it is removed. Removing the mudguards should be easy, but sometimes it isn't because instead of using hex bolts which would be super-easy to hold on the other side with a ring wrench - instead of doing this, they often use (mechanical) screws with round heads, for the screwdriver. I don't know why they do it - aesthetics, perhaps - but anyway it can be really frustrating to fixate as the screwdriver is to big and/or you don't get enough power either with that or with the "polygrip" [1]. I always put hex bolts there instead, and so far that hasn't came back to bite me. [1] https://sv.wikipedia.org/wiki/Polygrip -- underground experts united http://user.it.uu.se/~embe8573 |

I'd never use flat or cross-head screws for mudguard bolts - normally Allen (hex sockets), or sometimes normal hex bolts. If I had a bike which came with them I'd probably replace them.

Allen should work as well in close to all cases because the keys are thin, and bent, which gets them in and out of the way, and they get a good grip. However hex bolts should be idiot-proof because you get such a good grip from all angles with a variety of common tools. -- underground experts united http://user.it.uu.se/~embe8573 |

The wiki page has the answer - it was the brand name over here. |

Body Men, people that used to repair damaged auto sheet metal, used a "Plenishing hammer" to smooth out the tool marks caused by bashing it back in shape. You can do the same thing with aluminum. -- Cheers, John B. |
