[jim55]

hi peeps ..my crank is threaded ,,the pedal is fine but the thread in the crank arm is gubbed ,,now iv tried to drill the pedal spindle and fix it in place with a bolt and its impossible to drill does any body know of any product to join these together lika a glue /kinda paste thing ?obv the worst case il have to buy a new crank but its a rat bike and i dont want to spend on good kit ,,any ideas peeps

New crank. You don't want a pedal falling off. Sjs cycles sell single cranks.

New carnk is ideal, but a HeliCoil insert may do the job...doubt that it is much cheaper though.

There will be a Loctite product that would probably do the job but they are quite expensive, it might be worth cadging some (as in take the bike in with you) from a friendly engineering works or old-style garage. I don't think you could ever trust it though.

Is there anybody near you that does bike recycling? There's one near me http://www.fifebikeworks.org.uk/ so I'm sure there must be more.

helicoil was my first thought its prob gona cost a fair bit but good tip on the recycling thing ,,theres a few cleansing yards and i have acess (i work for the council)so il check them out (forgot about them ,,thanks)

Would you ever be able to trust a repair sufficiently?
A helicoil would probably be ok but anything involving any kind of glue/bonding agent would always be a bit of a worry and you'd have to replace it eventually anyway when the pedal bearings go.
If its a left crank, you can get a new one from St John Street for about £10, otherwise New crankset from Spa for £20, if they are compatible with what other components you have.
