Are you sure its a cassette and not a freewheel? yep, I turned to Sheldon to determine that first.. (http://sheldonbrown.com/free-k7.html) Tony, I tried your squeeze technique with the wrench+chain whip. It felt like I was getting more leverage, you're right, but still no movement. No vice at my disposal at the moment.. Is sudden force (ie a hit with a lump hammer on the wrench) a really bad idea? No, try the lump hammer. Its best though if you can put the whip and wrench in the above squeeze position with the handle of one resting on a hard surface (top of a wall or such like) and then hit the other handle. Usually its getting the first budge out of it that's difficult. Once that has happened it tends to undo easily. -- Tony "Anyone who conducts an argument by appealing to authority is not using his intelligence; he is just using his memory." - Leonardo da Vinci |

As an alternative, if you can lay hands on a piece of tube which will fit over the end of the wrench... In the days of obstinate freewheels with big sprockets, I used a 10" adjustable spanner with a Bickerton seat tube artfully flattened at one end to extend the total length to about two of the BRITONS' feet. Back then a source of Bits of Borken Bickerton was readily available in the form of Lt. Col. Larrington (retd.), who would break Bickies with monotonous regularity until such time as they started flogging rebadged Dahons instead. -- Dave Larrington http://www.legslarry.beerdrinkers.co.uk Putting just the right amount of gin in your goldfish bowl makes the fishies' eyes bulge and causes them to swim in a very amusing manner. |

Sometimes needed a gert big vice and two gert big folk tugging on the wheel to break it free. On a tour once two cogs made a gentle tinkling sound as the remnants hit the tarmac. Had to disassemble the freewheel, with hammer & chisel, courtesy of a friendly NLBS, grip the body in a vice and grunt like hell to break it off. Colleague was on standby to DHL a complete new tandem wheel from the UK had we failed. -- Tony "Anyone who conducts an argument by appealing to authority is not using his intelligence; he is just using his memory." - Leonardo da Vinci |

I read somewhere that the old Sun Tour Alpine 14-38 freewheels were fit and forget in tandem use, coz once it'd done a few steep hills, no tool made of Man was ever going to get it off again. I'm not sure I'd fancy that... -- Dave Larrington http://www.legslarry.beerdrinkers.co.uk They came for Dani Behr; I said: "she's over there, behind the wardrobe". |

If you are goung along the percussive persuasion route, you might want to try giving the lockring a sharp tap along it's axis with a small hammer. If all else fails I use a small pair of stilsons (18"). If I am at my dad's then I can borrow the medium sized ones (30" or 36"). His definition of large is 'as tall as him' (5'4"). ...d |

Quoting Tony Raven :
Nothing like a tandem to weld the freewheel to the sprockets. Sometimes needed a gert big vice and two gert big folk tugging on the wheel to break it free. One of that was enough to convince me to put a cassette hub on. -- David Damerell Kill the tomato! Today is First Leicesterday, September. |

Thanks to all who replied.
To end this debacle, after hitting, groaning and trying all the tools at my disposal, I took it down the LBS. They just put the wheel in a vice, had both tools with considerably longer handles than mine, and crunch. All done. Maybe I'm just weak. |

I remember a friend who had a seized pedal on a crank; we tried everything with no success. In the end we used an extension bar on an adjustable spanner, which finally released it. She now religiously keeps the pedal threads greased. John |
