![]() ![]() Round vs.square cross section was not a problem.īy just using an all gear train these things work, but with the belt in there it’s got a short time to work. I found “o” rings the right length and thin enough. The belts were soft and grease creep covered and smaller than anything in that MCM catalog. Years ago I had a set of motor-slide-pots in a Yamaha organ that were belt driven and slipped causing the computer to mess the presets up again. ![]() When it won’t open, bang on the tray at the right time. The horror of having your VCR not cough up the horror movie rented last week! The same for CD player slide out loaders, and perhaps that DVD burner in your computer still. It sounded nicer, even though every movie would add a sound effect for that scene. They thought if all gears were used instead of a belt that an undesirable noise was made so the belt was used. Many VCR’s would use gearing from the loading motor except for the first drive element. There never was a better time bomb killing the function of stuff than rubber belts and tires. Interesting how the oligiodynamic effect works for electronic components too… though anything that oxidizes or a microorganism can eat on or dust they eat on… can get nasty in moist environments over time. The product is impressive for health uses too. I have a project like this coming up in the future and so far used some Code Blue EliminX triple strength-enzyme with silver blind spray to kill off the germs. ![]() I even wonder if there is or was a gap in the electromagnetic-mechanical or really mechanical-electromagnetic sciences and engineering for a period until the hybrid vehicles came out and MEMS. String is less noisier also than gears or sprockets. We don’t see the mechanical dynamics so much common now days as was in days past. Maybe fishing line or cat gut? Anyhow, more seriously… this is an interesting topic when thinking from the mechanical electromagnetic/electronics ways and means to design systems. The temperature sensitivity and hygroscopic nature of chocolate pudding. Posted in classic hacks, hardware, Repair Hacks Tagged belt, comodore, Ninjaflex, vintage compuer Post navigation Of course, longevity concerns are always brought up when NinjaFlex is used, so hopefully keeps us updated. We’ve covered the difficulty in sourcing replacement belts for old hardware previously, so it will be interesting to see if others are able to make use of the research has done here. Careful measurement paid off, and the newly printed NinjaFlex belt had his Commodore loading and saving programs on the first try. just subtracted a smaller circle from a larger one in 2D, and then extruded that circle into the third dimension by 1.18 mm to match the height of the original part. The profile of the belt was square, which made modeling and 3D printing much easier. then reduced the diameter by 5% to take into account the stretching of the new belt. He started by cleverly replicating the path the belt would need to take with string, and then measuring the inside diameter of the string circle with his calipers. Besides, this wasn’t the only piece of vintage tech in his house that needed a belt replacement, so he figured it would be a worthwhile experiment.Īs the original belt was little more than dust, had to design his replacement from scratch. The belt inside of the cassette drive had become hard and fallen to pieces, and rather than hunt around for a replacement, reasoned he might be able to print one out of a flexible 3D printer filament like NinjaFlex. Which is exactly what found when trying to revive his newly purchased Commodore PET 2001. Unfortunately, now decades later we realize that these little belts are often the Achilles heel of classic hardware, getting brittle and breaking long before the rest of the components are ready to give up the fight. Tape decks, VCRs, even some computers: they all had rotating parts that needed to transfer power to other components, and belts were a cheap and quiet way to do it. It may be hard for some of the younger readers to believe, but there was a time when hardware was full of little rubber belts. ![]()
