How to Make a Wood Go Kart Part 2 of 3

August 12, 2014

Description:

This week I’m going to be adding the axle to the go kart frame and mounting the engine. To get started, I drilled two 1/2″ holes on each side of the frame on the back. This allowed me to bolt my pillow blocks into place with a 1/2″ bolt at 3″ long. I found it easier to slide the axle through both of the pillow blocks prior to bolting. This prevented me from having to deal with alignment issues from one side to the other. With my axle bolted in place, I added the sprocket and brake hub to each side and locked them in place with the set screws they came with. I added locking collars on each side as well to prevent anything from sliding. Now it’s just a matter of adding the wheels and tightening the nuts on the end. When assembling a live axle, you have to use key stock to keep the wheels, sprocket and brake drum engaged with the axle. With the axle fully assembled, I added two 2×4 crossbars where I needed to mount my engine. I glued and screwed those into place and drilled holes for my 5/16″ engine mount bolts to go. From here, I bolted the engine down to the frame and attached my chain from the engines clutch to the sprocket on the live axle. Next week I’ll be completing the rest of the go kart build so make sure you stay tuned!  If you would like to build this go kart, I’ve left a shopping/cut list to all the parts that you’ll need as well as an assembly guide that briefly takes you through each stage of the build.

Note: Parts on this list constantly change and parts that were previously available may not be available anymore. I’ll try to keep everything updated the best that I can. There may also be a few miscellaneous parts that I used that aren’t listed. Sorry for any inconvenience.
