Freewheel adapter for 1/2 inch shaft?

    I'm looking for a shaft adapter that has a 1.375-24 RH freewheel thread on it, and fits a half inch shaft. I know that a half inch keyed shaft is not capable of transmitting all the torque that a bicycle hub might see, but that isn't what I want to do with it.

    I have a reduction gearbox with a 1/2" input shaft that I would like to fit with a freewheel or a fixed track sprocket. The torque into this shaft will be only what a 25cc four-stroke motor can make at the crank, multiplied by maybe 1-1/2. (Not very much.)

    Does anybody know where I can buy an adapter like that? Thanks for your help.

    Now that's a good idea. My application is low torque, and the input shaft only has a flat on it and not a keyway, so an open bushing like that should do the trick nicely. Thanks for the tip!
