I'm basically finished with my winch spool. I have a little welding and Line-Xing to do after I finish the frame and give it a test run. It ended up being a little wider than I planned with 9.5" inside the wheels and a full 15" between the outermost points. Here is the materials list (prices are approx/guess):
2 piece go-kart wheels (Free)
2 three ft 3/16 threaded rods ($8)
2 three ft square tubes ($10)
2 pizza pans (yes thats right!) ($8)
1 3/4 go-kart axle (Free)
Misc nuts and bolts ($20)
1 go-kart sprocket (Free)
2 go-kart axle hubs (Free)
Comments and suggestions are appreciated.
