Carlton Lightweight Restoration Project - Help!

Hi All - got the bike up on the stand and discovered this pretty nasty bend in gear side seat stay - should've seen this a mile away!! I've asked the shop if they could build new rear wheel / cassette as I have some credit with them, they've also suggested bringing in to assess severity and mentioned cold setting frame? Does this sound like something doable / very expensive to you? By the look of this bend I'm assuming that the frame will defo need realigning for everything to run true?

Thanks in advance

If this needs cold setting you would need a proper frame builders jig for starters a gear hanger alignment tool would be needed. That’s what I’d be looking to do.....& even chat with a frame builder if you have anyone near to you...
If the tubing is gas pipe steel tubing then should be fairly straight forward to straighten up.

Just in case you thought cold setting was something very technical, it means bending it back to the shape it should be. It's often used to widen the space where the rear wheel fits to be able to fit a wider hub (and hence more gears).

All good stuff above. Don’t be shy or embarrassed about asking for help here, pretty much the whole community are a great help for anyone starting out or having a go.

Hi All

Thanks re above, I've been learning a bit on YouTube and hoping to attempt straightening myself.

I can't for the life of me get this cotter pin out!! I've tried bracing with hollow plank / WD40 / bar + hammer to release but it won't budge! I've looked to try see if I can buy a pin press but they seem ridiculously rare and ££££, I think I might have to ask the mechanics down the way if they can cut it out but just want to damage crank wheel! Anyone else had trouble with these??

Cheers

Jo

Thank you oaklec, I'm going to try set myself and use frame alignment tool to check

Thank you @Peachy! I'm very humbled with the amount of help I'm getting

Yup! They're pretty stubborn. You need to hit it harder!

Try supporting it with a bit of thick-walled steel pipe. It'll support it better than wood. Use a length of steel bar as a drift as it'll be easier to hit without accidentally smacking the chainring.

Next time though, leave the nut on. Undo it about a turn to a turn and a half and hit the nut. You can sometimes save the cotter pin that way, because it doesn't mushroom the end over.

Another thing to try (if you have it) is a vice and a socket from a set. You basically use the vice to press the cotter pin out and the socket gives it somewhere to go if/when it does let go. There are videos on the Tube of You.

Thank you @Jonny69 yes I’ve made a right mess of that pin! The other side came out without too much stress but not so much luck with this one, typical I saw advice on leaving nut on just as it got past the point of no return! Some more in the post - probably not the last parts I’ll need new
