Where I grew up an insult to the folks in the nearby city was to call a hammer a "Brummagem screwdriver". If my turntable was working I'd put on the "Bert and I" album now. Hang on clickety clickety -- I can get it on CD! http://www.bert-and-i.com/ Mike I'm old enough the have heard the original Bert and I guy perform in front of a Maine audience. Probably the joke that typified Maine humor, at the time, was the joke about the guy in a balloon who was lost and as he floated over the country side he saw a farmer plowing the "back 40" and shouts down, "Can you tell me where I am?" The farmer looks up and shouts back, "You are up in a balloon". -- Cheers, John B. |

Add a 1mm spacer behind the low gear, lube and torque your lockring and that rattle will go away. OK, now I get it (I think), by rattle, you mean what I've called crash sounds. You suggest I should remove the new cassette, put in the spacer, and put the cassette back on? Even tho I don't experience anything negative using it as it is? And this time, no crash sounds or "rattle" when pulling? I think there is a bit of a translation problems with crash and rattle :-) To most Americans (who is whom you are usually talking on this site) a "crash" is the sound of you hitting a school buss at 30kph while "rattle" is the sound of a spray paint can when you shake it to get the paint well mixed :-) -- Cheers, John B. |

A digital one with a hook where you normally lift a suitcase with to see if it is still under the required 50lbs. Under $10. ... really? How do you "mount" it all? Even if it could be done, ... It can be done easily. Most of my wrenches have either a loop or a circumferential groove. If they didn't I could quickly add one. I put the cassette together (mostly I have them in pieces to be able to mix and match), tighten all the stuff by hand. Now I slip the wrench onto the Shimano tool, crank the wrench by hand but not too hard, press the button on the suitcase scale, slide the hook through the loop or let it slip into the groove at the other end of the wrench and then pull on its handle until the display shows the "weight" I calculated to indicate correct torque. Ok, you first have to measure the length of your wrench but after some years doing it this way you already know that. You could also write the "scale factor" onto the wrench. I can almost bet this method is more accurate than a ratchet but that's not the reason I am doing it this way. My dad used an analog butcher scale. Works just as well but those can hurt if they accidentally slip off the handle and go flying. ... isn't this like a poor-man's torque wrench and much more complicated at that? No, it is very practical. I try to be a minimalist with many things. Why buy and store a torque wrench when it is not truly needed? Then there is the ratchet mechanism. When it gets old how do you know it is still accurate? The suitcase scale I can easily check. I might comment that at one time I worked in the Edwards AFB (USAF Test Center) shops where we had a "Torque Wrench Shop" where the guy tested and recalibrating torque wrenches. I once asked him how many of the torque wrenches turned in for calibration actually needed adjustment. He said "all of them, even the new ones". The calibration bench was simply a shaft with an arm to which weights were added :-) of 40 nm, I know only this is a lot and the reason I know this is every time I remove it, it is stuck like, very firmly! It is a lot. But I thought you Vikings are all supermen with lots of muscle, exclaiming a loud "uff da" and off the cassette comes :-) Sorry, wrong country. That's the Norwegian vikings. We on the other hand were clever merchants even then :-) On my Shimano cassettes the end piece that tightens it up has teeth inside so it will make a loud ratchet sound at the end. I guess that was done so it won't come loose during a ride. If the outer sprocket would ever slip off and turn free while pedaling hard you could have a major crash. So it better not come off. Indeed, I figured it was something with the casette. The smallest sprockets (two or three?) are somewhat loose to begin with. Do you know what is actually making the sound, functionality aside? You mean when tightening? Take apart the old cassette. You'll see knuckles on the inside (pointing towards the wheel) of the fastening screw and also knuckles on the surface it comes to rest on. Those knuckles will cause that rat-tat-tat noise when tightening a cassette. Think of it as two washboards rubbing on each other with the wavy sides touching. -- Cheers, John B. |

A digital one with a hook where you normally lift a suitcase with to see if it is still under the required 50lbs. Under $10. To get to 150lbf-ft for the front wheel bearings on a BMC Mini (not the BMW MINI) I'd put a stout tube on the end of the breaker bar then calculate where to stand on it. To undo ditto but stand further out & jump on the tube. Mike I've seen a 19 foot propeller installed on a 3500 H.P. engine torqued the same way. Except the wrench handle was about ten feet long and the guy was hanging on the wrench with his feet about three feet off the ground :-) -- Cheers, John B. |
