    What motor and gearbox combination is needed for pulling a sled over 3 days?

    I'm loving the cuckoo clock concept. I'm tempted to try it just to see the look on people's faces! Slim

    What motor and gearbox combination is needed for pulling a sled over 3 days?

    Great stuff guys, Now we're getting somewhere! The more ideas the better but at least I've got a potential supplier for the components. Controlling those revs could be an issue, as pointed out. Any more thoughts very welcome but thanks to all so far. Paul

    What motor and gearbox combination is needed for pulling a sled over 3 days?

    Hi Chris, Thanks again. I've tried to work out ratios for normal gears and the figures, as you suggest, are crazy. I guess you're right about the worm gear solution but the problem still stands. What the heck do I buy to achieve the desired result? I can deal with the engineering to...

    Chris, Totally agree. It's the gearbox side of it that I'm struggling with. I imagine I will need a motor with gearbox going through another gearbox. That's what's making my head hurt! Slim

    What motor and gearbox combination is needed for pulling a sled over 3 days?

    Chris, Many thanks for your input. I had considered the worm gear option but it would have left me with similar issues and added engineering complications and expense. I envisage using non stretching fishing line on the take up spool, in fact that's pretty much exactly what I'm after - a...

    What motor and gearbox combination is needed for pulling a sled over 3 days?

    Hi All, I have a project which involves pulling a sled (wheeled, on rails - low friction) weighing approximately 15kgs over a set distance and time. The distance is approx 60cms and the duration is 3 days. To minimise cost I intend to anchor a motor(ac or dc)/gearbox combination and use a...
