Does anyone know if there is a simple way to mount a 21 speed sprocket casette onto a shaft that is either 3/4" or 1"? The casette would be removed from the hub and the hole inside of a casette is plenty big enough for a 3/4 or 1 inch shaft. The shaft it would be going on is a Comet reverse gearbox.
Bike sprocket casette on a shaft?

Bike gearbox?
keep in mind that there is almost ten times the torque applied to the gears and chain than what it is designed for,
the teeth will strip if you're lucky, if not the chain will snap...
So try to avoid bicycle chain on a self propelled kart.
Now pedal carts...
There are indeed pedal karts with a multispeed gearbox;
I think "Berg" and "Dino" both have shifter karts,
but I don't know if it's on the axle or
a jackshaft-esque set up nor the axle diameter.
Maybe you want to research in that direction to see how they did it.

I've tryed this with a complete machine shop its impossible. Don't bother trying. I have 21 year and my father has 42 years machine shop experience and nether of us could do it.
Sounds like a challenge
No honestly, I have no idea on how to do it, but a casette alone has a rather large internal diameter, I'm sure you can mount that (making an adaptor of some sort) rather easily to a keyed shaft.
The thing is, it'd be rather difficult to mount the derailleur to it,
not designing a completely new one.
But I wouldn't necessarily say it's impossible, but it's impractical for sure

[EDIT]
Well.. a casette and a derailleur on a tricycle rear axle:
and another one (electric conversion)
And although those don't look like a 3/4" much less a 1" axle.. it's still very likely possible to achieve that

Its called a freewheel adapter, google it and you will find a number of people selling them.

Not that I have seen. Most bicycle aplications arent going to need the weight/strength of a 1" axle.
With that being said, Im pretty sure that one of those could be bored out to fit 1", if one was so inclined.

I've been on that site before. Lots of cool stuff. Been wanting to place an order from them for some time. Can never figure out all I want to buy.
