In order to reach the conclusion that you were promoting in that thread, your argument was predicated on: A) Look not being smart enough to have a CAD file or drawing of their cleats and the mold needed to make them, as well as having "lost the original cleat model." And your ignorance about whether the sources from which they get their cleats molded even bother with a CAD file. You get funnier by the minute since you don't seem to have a strong connection with the way they do business around the world. Sorry, Tom, but what makes you think they *wouldn't* use a CAD file or drawing? Based on your posts, I know that you aren't at all familiar with how machining is done. A mold for those cleats (and it would be for several at once, not the one at a time style that you seem to envision) is done on CNC equipment or on a EDM machine (and the graphite electrode for that would be cut on a CNC mill). If a shop has CNC, they will have a CAD/CAM system and, hence, a way to use CAD files. Talk about being unfamiliar with how they do business around the world. You think it's all done on Lagun manual mills? Funnier by the minute, indeed. By all means tell us how Look cleats are made and where and by whom. You're flailing in an attempt to divert attention from the fact that you're unfamiliar with how commonplace CAD is. How do you know there were "subsequent molds" and they weren't still using the originals? Wild Ass Guess - again. Wild ass guess? A guess certainly since I am not privy to Look's books. But then I happen to know that most of North Africa has shops that still use hand operated machine tools. So if you want to make a replacement mold YOU USE THE OLD ONE AS A MODEL. But not being all that bright you haven't any idea what I'm talking about. I'm really laughing here, Tom, and not with you. That there are shops in North Africa ("I happen to know..." - snicker) that still use manual machines means --- what? There's plenty of shops in the US (and France, for that matter) that use manuals. A glance at the cleat tells you that it is *highly unlikely* for the molds to have been made on a manual. I am aware of what can be done on manuals - I started using them in '74. I also know what can be done on CNC machines, with and without CAD/CAM, by a good person, so I'm not underselling that aspect of the machine shop world by any stretch of the imagination. But having been in machine shops as long as I have, I have a good idea about what machines and processes are appropriate for parts. See, I get paid real money for that particular skill. Part of the problem here is your misconception of the molds - you're laboring under the illusion that they take a "machined male model" and pour some stuff over it and when it hardens, it's a mold. That method can be used for short runs on simple parts but *real production* is, as I've told you repeatedly, done with metal molds (aluminum or steel for the most part) that have the cavity machined into them with mills and/or EDM. There are two pieces (or more in certain more complex molds) that mate up with runners for the material, some means of dislodging the part (air, ejector pins or stripper plates, for example) and a few more bits, depending on the size and complexity of the mold and parts. See: http://en.wikipedia.org/wiki/ImageSC05440.JPG I suggest that as long as you're being stupid you might as well tell us how many Look pedal sets you own. You're flailing again... Posing that question as a means to prove that I understand what it takes to do production molds for a cleat is, well, stupid. See, this is where your contrary and superior mindset causes you trouble. You're locked into the idea that your concept of how the process works and cannot manage to see that others might actually be familiar with the real methodology. This could easily be a moment where you say, "Oh, so that's how it gets done" and you'll have learned something. Instead you set about making yourself look silly. Certainly succeeded there, I must say. -- tanx, Howard Fabergé eggs are elegant but I prefer Fabergé bacon. remove YOUR SHOES to reply, ok? |

I remember clipping out of Looks, but since switching to Time I've never clipped out (and they mostly fixed a ankle/calf problem I had through to much float with the red cleats and no float with the black ones.) |

... The last set of Look pedals I owned were the reason I broke my collarbone. Yeah, the quality went WAY down for awhile and I bought a bunch of DuraAce look-type pedals to use. Now they're back to being fairly good. The cleats had become absolute crap and I couldn't use Look cleats anymore because they rattled in the pedals. The latest cleats are back to working well. |

My cleats fit fine, but the spring tension in the pedals wasn't sufficient for standing starts. I pulled out once while doing starts on my road bike and a second time a couple of months later on a track bike. The fixed gear kept turning the cranks and launched me over the bars. |

I can hardly believe that you could pull out of those pedals with new cleats and a good fit. I haven't pulled out of them EVER except when I wasn't clipped in properly. I do know that some of the cleats and pedals would allow you to sort of clip in off to one side and then you could pull out. But it felt funny and would turn your foot a little so that you would unclip and reclip in so that it felt right. The Shimano DuraAce pedals are really strong - much better than anything but the top of the line Look. I've seen people pull out of just about every pedal on the market though. Oh, except for those early Cinelli pedals that required you to pull the little slide out in order to detach your shoes from the pedals - those had to be the best idea for track bikes. The only problem was that if you fell over you couldn't reach them to get out of the pedals. |

See, Tommy, this is exactly what started this part of the thread: I said that you constantly argue with people who know what they're talking about. You fire off a bunch of comments based on crazy-ass suppositions and then proceed to criticize and denigrate as "stupid" the people who respond knowledgeably. You have an evangelical belief in your own correctness at all times, in the face of contrary evidence. "North African machinists", my ass.
