Well, after my first and mostly successful wooden gokart, I decided to build a sturdier and better one. I used the same wheels, engine, axles, and seat from the first one. For specific details on mounting the engine, sprocket, and wheels, visit my first gokart. This is definitely an improvement from the first. For your convenience, I made a 3D Sketchup model. Download it here. The following steps contain pictures from Sketchup. I recommend you use Sketchup to find the exact dimensions.
