My friends and I are going to build a go kart this summer and I am preparing a preliminary cost estimate. How much does it cost to build (i.e. cutting and welding) a frame together, and what would be a good material to build it out of (steel or chrome-moly)? There are some pre-built chassis around the internet, but they cost anywhere from $200 to $700. I am planning to use at least a 5hp engine and maybe a torque converter, so strength must be taken into account.
