Zip line racer

Have a zip line that needs riding? Then this is the project for you!

We take a small bicycle/trailer wheel and a couple pieces of hardware to make a fast, safe and weather resistant zip line rider.

Tools needed:
2 Crescent wrenches or a good wrench set
Large flat blade screwdriver (to remove the rubber tire from the wheel)
5/16″ drill
3/8″ drill (depends on the size of your tires hub ears)

Materials needed:
2 – bars of flat aluminum stock (1 1/2″ wide or greater)
1 – 5/16″ x 1 1/2″ bolt
1 – 5/16″ lock washer
2 – 5/16″ nuts
1 – 1/4″ x 3″ eyebolt
1 – 1″ -> 2″ metal tube 12″ or longer
1 – 1/4″ fender washer
1 – Small quick release bicycle or trailer tire

The tire is the hardest item to procure. Mine came from a bicycle trailer for kids. It was to be used to turn the trailer into a stroller but that never worked well.
