removing rust from bikes and guns
Are there any tricks to this?
I have the usual stuff: sandpaper, emery cloth, and brushes (nylon, brass, and steel), in some creative shapes including the bottle brush, a Y-shaped thing etc. I found it is beneficial to use the vise for the wheels, especially in combination with the emery cloth as it can enclose the hub shell. Rotating the wheel might save some time. Today I spent almost the entire day removing dust from a Favorit bike from Czechoslovakia. It came with Torpedo rear rim and wire tho (and not the "original" copies they did). Perhaps it was put there at a later stage. Czechoslovakia was dissolved in 1992/1993 so I suppose it is at least 23 years, 5 months, and 6 days old, unless of course it took them some time to reconfigure their machines to show "Czech Republic", right? Anyway the age of the bike should not be blamed for the ridiculous amount of rust it had. But now it is all shiny! Also, as a side not, I'm reading a book on the French foreign legion, namely (in Swedish) @book{soldaten-som-inte-kunde-dö, author = {Knut Häll}, ISBN = {91-36-02636-0}, publisher = {LT}, title = {Soldaten som inte kunde dö: svensk äventyrare i Främlingslegionen}, year = 1987 } and the author tells a story which begins with them removing dust from their weapons ~"tho it was forbidden to use sandpaper or emery cloth, we did it anyway". Why do you think that is? Is it to force people not to handle the weapon so rust will not appear in the first place? Or are there disadvantages to sandpaper/cloth - perhaps fragments get into the machinery and spoil the gun? -- underground experts united .... http://user.it.uu.se/~embe8573 Emacs Gnus Blogomatic ......... http://user.it.uu.se/~embe8573/blogomatic - so far: 48 Blogomatic articles - |

Well, sandpaper removes material, so ultimately, if cleaned enough times, the item would disappear :-) My grandmother had a "kitchen knife" that she had, she told me, since she was first married that from sharpening had worn down to a very thin and narrow blade. As for books, it depends on what era was being described. The Chassport 1866 appears to be bright polished steel and cleaning it with sand paper wouldn't effect the finish a great deal while one photo of the Lebel 1886 seems to show a blued finish and cleaning with sand paper would probably destroy the finish. As for bicycles. If the bike is disassembled I have had good luck cleaning steel parts with an acid bath. I commonly use a very strong bathroom tile cleaner sold here that has as much as 20% hydrochloride acid. Note that this stuff is dangerous. If splashed on you it will cause severe burns and will ultimately erode steel completely, and I said "disassembled" because after the acid has done its work one needs to wash the acid mix entirely off using water and then coat with some sort of oil, WD-40 works pretty well, as being chemically clean will rust almost immediately. Do not use this stuff for aluminum parts as it erodes aluminum very rapidly and also creates hydrogen gas which is highly inflammable - see Zeppelin+Hindenburg. -- cheers, John B. |

Add paint and you're done. Nobody paints guns, so you'll need some other kind of protection. Gun bluing does little in the way of rust protection.

Anyway the age of the bike should not be blamed for the ridiculous amount of rust it had. But now it is all shiny! For removing rust I have had some success with products containing oxalic acid, particularly one called "Barkeeper's Friend". The next step up is phosphoric acid, "naval jelly". Some scrubbing is still required, but better living really is attainable through chemistry. Also, as a side not, I'm reading a book on the French foreign legion, namely (in Swedish) @book{soldaten-som-inte-kunde-dö, author = {Knut Häll}, ISBN = {91-36-02636-0}, publisher = {LT}, title = {Soldaten som inte kunde dö: svensk äventyrare i Främlingslegionen}, year = 1987 } and the author tells a story which begins with them removing dust from their weapons ~"tho it was forbidden to use sandpaper or emery cloth, we did it anyway". Why do you think that is? Is it to force people not to handle the weapon so rust will not appear in the first place? Cleaning stuff all the time keeps soldiers out of mischief? Or are there disadvantages to sandpaper/cloth - perhaps fragments get into the machinery and spoil the gun? That could happen, too. -- |

The Springfield muskets, both rifles and un-rifled had bright finishes certainly from 1795 until the 1863 model. No anti-rust at all. But he was asking about removing rust and mentioned the rifles as an argument to using sandpaper to remove rust :-) -- cheers, John B. |

Why they did it was because it worked. But why it wasn't allowed the book doesn't say. Perhaps because it it were, the troops would misuse their rifles because they could always get them shiny again. Or perhaps the papering spoiled the guns (depending on to what degree it was applied and on what parts). If we learned the reason, it would be interesting to see if it is applicable to bikes as well. -- underground experts united .... http://user.it.uu.se/~embe8573 Emacs Gnus Blogomatic ......... http://user.it.uu.se/~embe8573/blogomatic - so far: 48 Blogomatic articles - |
