Rusted Forks??
Postby RubenS » Thu Aug 22, 2013 3:57 pm
I am repainting an old steel frame bike. The forks have a small drainage holes on the tubes. When washing the paint stripper off some water got in, and when draining it, out came some rust flakes along with rusty water. I have had them soaking vinegar to remove the rust, and have then sprayed in some WD40 to try and stop anything reoccurring.
my questions are... How do I know how structurally sound the forks are? assuming they are good, what can I do to ensure stays that way???

Think I will go the fish oil and then seal it all up. Pretty confident rust is sorted now.
here are some more pics if anyone is interested.... how it looked when I got it and a few of the frame as a work in progress...

limits the amount of oxygen? doubtful.WyvernRH wrote:Also, when you are happy that all is dry inside the forks, block up the holes with filler, Araldite, whatever. This stops more crap getting in and limits the amount of Oxygen available for rust formation to the small amount in the sealed tube (assuming the builder did his job properly at the fork crown..)

Why? The tube is (should be) sealed at both ends with brazing metal, steel and bronze aren't permeable to air.cooperplace wrote:limits the amount of oxygen? doubtful.WyvernRH wrote:Also, when you are happy that all is dry inside the forks, block up the holes with filler, Araldite, whatever.

That's why I suggested the chap 'block up the little holes' in my original post..Duck! wrote:Not so. Many forks have a small breather hole near the tip of each blade on the inner side.
Actually, if you are good you can do without breather holes and those that use them often seal them up.
