... how much rust is too much rust?
Re: ... how much rust is too much rust?
That looks really good.
Re: ... how much rust is too much rust?
The chainstays on my winter commuter have been in a similar state to the OP's for several years. I recently cleaned off the rust with a wire brush on an angle grinder, plus a Dremel and sandpaper to get to the awkward bits. I was pleasantly surprised at how little pitting there was and how well it cleaned up. I finished the job with a wipe down with phosphoric acid (to neutralise ant remaining traces of rust) and a coat of enamel paint.
All set for a few more years of hard grind!

one of my chums rode his steel framed commuter until the chainstay bridge had actually disappeared completely, and parts of the chainstays were pitted right through (yes there were holes...).
Up to a certain point rust looks worse than it really is (there is still plenty of metal underneath) but later on it can serve to disguise how little metal there is left.
If you are worried about a steel frame cracking, best to paint it a light colour and keep an eye out for cracks.
cheers

Very nice, & a good degree of symmetry....pedal angles could do with a little more concentration!!

I finally retired the old girl, got fed up with constantly fiddling about to get the brakes properly on 700c wheels, it was built for 27".
After a while, I cut it up with an angle grinder, and found.....nothing!

Curious. Do you think maybe you have got used to riding stiffer frames and going back to an old style flexy frame set alarm balls ringing?

Its tempting to think that, but the next touring bike I had was 531ST, so still the traditional inch and inch and eighth tubes, although a bit thicker gauge. I forget the exact sequence, but I also had a couple of Raleigh mountain bikes and then an Orbit Romany roughstuff bike. The Romany I still ride, and its still a stiff frame in Reynolds 853, inch and a quarter down tube and inch and eighth elsewhere.
So I don't know! I felt at the time that the old bike had got more flexy, but I don't have anything definitive to go on.

I wish I could flex more as I age.

Brilliant. Can we keep this thread please, to show to all the nay-sayers who think that the first sign of rust means the scrap yard?
