Roller Belt Redux
I'm posting this so others who Google search can know that there is
hope for those of us who have nearly 30 year old (27) Tackx rollers with the fan units and belts -- and to thank David Scheidt who put me on to a source for "custom" made drive belts, McMaster-Carr. I couldn't find any source for replacement belts, so I glued my last one together, and it finally failed last week after maybe 10-15 hours post-super glue use. I looked up an old post and saw the recommend for McMaster-Carr, measured the old belt -- It had been hacked to get an angular gluing surface and I had to guess a little, and I ordered up some poly belts 3/16th. They were as cheap or cheaper than similar mag unit belts, and the shipping wasn't punitive. BTW, it's a 19" circumference belt. -- Jay Beattie. |

Just curious - are those made from round solid polyurethane cord? My similar vintage rollers were made by a friend and former frame builder. Last year he "warrantied" the original drive belt that had broken - he still had NOS drive belt material on hand. But the cool thing is that a looped belt is readily made from an appropriately sized length of polyurethane cord by "welding" the ends. They are simply heated until slightly "oozy" (technical term) and then held together until they cool. No glue involved. DR |

DR Yes, 3/16th polyurethane "cord", although McMaster-Carr also specs other materials that are more exotic and can withstand nastier environments. My prior belts were rubberier -- and I didn't try to weld them, but now that I have a replacement, maybe I'll see if the surviving belt is weldable. They also sell raw cord, so if you're a home welder, you can make whatever you want -- main belt, mag or fan unit belts, etc., at least with the polyurethane material. -- Jay Beattie. |

Next time you need to make a belt like this you might want to try melting the 2 ends of the material with a butane torch or a cigarette lighter and pushing them together for about 30 secs,then dip the joint in cold water. There will be a small amount of 'flashing' which you can then trim off with a razor blade. Hope this is helpful. |

Most of the time, I think they're lower than i'd pay anywhere else. A large part of that is that they have have a big distribution center right outside chciago, and I work (and have packages delivered to) in an area of chicago that's still modestly industrial. I've gotten a number of orders delivered by courier the same day they were ordered, which is unexpected. I suspect that happens when someone says "I got have this today", and package near by fit on the truck. Part of the fun is not knowing what it's going to cost to ship until they ship it. That's not unreasonable on their part, they sell lots of little things, and it's very hard to figure out what it's going to cost to ship until you've got it assembled into boxes. The first time I got a same-day parcel, I got it before the charge showed up on my credit card, and I spent the weekend wondering how much it was going to cost. -- sig 116 |

Actual Tacx roller belts are readily available and cheap. The material may be sliced and melted together with a lighter to make a pair of fan drive belts from a standard long belt. We stock the short ones but I don't know if those are yet a current item. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

We stock the short ones but I don't know if those are yet a current item. Tackx has a short belt that is too short. I bought two of those by mistake and never returned them . . . so to test the melting together thing, I melted them together this afternoon. Kind of sloppy, and it takes more time than one would think to clean them up with a razor -- but I think it will work as a spare. I paid about five bucks a belt finished from McMaster, which is not bad considering that they are really well finished with a barely visible seam. But then again, I wonder why I didn't think of doing this before. Oh well, I'm probably out about five or ten bucks tops, and I do have swanky new belts. -- Jay Beattie. |

Another company which offers products similar to McMaster-Carr is Grainger.
