[Kartbuilding] Rear axle

[Stephen Burke]

Hi Maxime,

Thanks for your email.

Yes, it is quite tricky to get the sprocket and its carrier attached
correctly to the rear axle. It is the same with the brake disc.
There are a few methods for achieving above. What method you will use
will depend on what resources you have available.

    * It is possible to make a rear axle. Do you have a Metalwork lathe?
      Would you know anyone in a Machine Shop who could turn the rear
      axle on a lathe for you?
    * If you had access to a Lathe, you can get special carriers turned
      for the sprocket and brake disc.
    * Getting access to a Lathe would be the best way to complete the
      rear axle with 100% accuracy.


If you don't have access to a lathe, you can still make the rear axle,
but you have to be very careful, otherwise it will not be a full success.
What wheels do you have? This will govern the type of homemade hubs you
will need to use.

If you want, email me a photo of the wheels, sprocket and brake disc you
have, and I'll do up some images on the parts you need to get or make.

Best of luck,
-steve
