How do you attach a wheel to a shaft?

[Joe Johnson]

It is hard to recommend a solution when we can't really see the problem.

Do you have a picture or can you scan in a sketch of your set up?

P.S. If you are using Skyway wheels, we have had good success chucking the wheels up on a lathe, boring out the center hold to a whole number (1 1/8 for example), then pressing in shaft and pinning the shaft to the wheel. The larger diameter hole makes pinning an easier thing to deal with.

Another method is to use the Small Parts Inc. adaptors.

Yet another method is to use bolts and spacers. If you have a sprocket that you can get the torque to, then go directly to the wheel spokes with the torque rather than going to the shaft and then from the shaft to the wheel. One way to do this is to put bolts into the sides of the sprocket. Use the spacers to key the bolts perpendicular to the sides of the sprockets. It can work well.

Finally, give us a sketch or a picture to work with and we will have better ideas to share.
