    I sure hope that last gear does not have anywhere to be any time soon.

    Don't stop cranking it before you achieved a full turn on the last gear, or the world will come to an end! You started it, you have to finish it!

    I did.

    The plastic on the crank spindle started melting lol

    Dang. I did not say go full blast ;) do you have that video too ???

    Imagine the speed if you had driven the red-dotted wheel ......

    It could be turned by hand up to the gear with the green dot, then it became physically impossible by hand. I didn't dare try hooking up the drill because I thought the plastic gears would just explode

    Already by the green dot gear, one turn of that was spinning the 1st gear about 500-1000 times

    Yeah, probably would explode. Only way might be to set it in motion from the green one and take it overt on the red one once the cogs picked up some speed. But most probably they will melt before that, the speed will be much to high.

    But fun, thnx for sharing!

    "What does it do?"

    "Gears"

    Is this the worlds weirdest excercise equipment or some other purpose or a 'hey look what I can make' thing

    It's an idea I came up with when I was 24 years old, so that's 27 years ago. I finally managed to salvage enough gears to make it happen.

    I'm sure I'm not the only person to come up with this, it's not a particularly clever thing it's just neat to me.

    What's the ratio on this bad boy?

    I'm actually not 100% sure because I made it all with salvage gears that I've gathered from years of electronics repair. A couple of them I had to glue two together to get the reduction.

    I think there are four that are 11:44 (1:4) and four that are 22:44 (1:2)

    4x4x4x4x2x2x2 = 4096 turns of the first wheel to make the final wheel turn once.

    Again this is an approximation because it's all salvage, and I didn't really count teeth except a few times. Also I later attached to the handle and the offset gear there, and there's a teeth mismatch so I think that's like 62:50 or something oddball... I'm not counting that.
