After building this go kart there are some things that I would have different if I had the material. I would have made the rear axle solid all the way...
Me and a friend got tired of being bored and we don't have money to go out so we decided to build a go kart from scratch using materials we found around the shop. We custom built every single part on this go kart, from the steering to the brakes. This project took 3 days and at a total cost of $0.
What you will need:
Square/Round tubing for frame and support
Step 2: The frame
We built the frame out of 1" square tubing that has been sitting next to the house for years. We started by researching racing kart frames and came up with a design.
Step 3: The spindles
To build the spindles you take a piece of 1" flat stock that is 7" long and bend it so you have 2"-3"-2" U shape. Make two of these. Once they are bent, drill a hole the size of the bolt you are using in the top and bottom. Now cut a piece of round tube that is a little bit smaller than the inside height of the spindle. This piece needs to be a snug fit to the bolt your using so the tube will turn freely around the bolt but not so tight that its difficult to rotate. Now for the part that actually rotates, I used 1/2" square tube to make this part. Weld a bolt that is long enough and wide enough to go on the wheels you are using onto the piece of tube that the bolt goes through. At a 90 degree angle to this piece weld another piece of tube that the steering components will attach to.
Step 4: Steering shaft
The steering shaft is a piece of 1/2" hollow round tube. The length is determined by where you want the steering wheel. we made our shaft about 18" long which is perfect for use cause were both skinny. You will need two industrial washers to hold the shaft in place so the wheels will actually turn instead of the shaft.
