I got my inspiration from:
http://thirstybeachlandscaping.com/index.html (for some reason the big bike section isnt working right now)
I tried to use much of the same design as "The Boxer" but I changed it to three wheels.
This is The Boxer:
This is my design part way done:
As you can see... the design shares some components, but has 3 wheels!
Here are some of the materials I have got together:
Bearings, Shaft, bearing hubs and races, shocks, wheel materials, disc brake, the round tubing that I needed rolled (by Van Bebber Brothers in Petaluma CA), and a tube notcher that I got from Harbor Freight that attaches to a drill press.... I hope it makes enough notches before it breaks!
Here are some pictures of the materials i've got together:
