Picture of Homemake Wooden GoKart 2.0
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.

Step 1: Step one

Put two 3 1/2" x 1 1/2" x 75" beams 3 1/2" apart.

Step 2: Step two

Place a 22" long beam underneath. Do not attach. Next, place a 3 1/2"x3 1/2" in between the long beams. Place a 1/2" thick beam and attach it to the longest two beams. Then, drill down the middle of the 1/2" thick beam through all three layers. Put a bolt Into the and tighten. The bottom beam should pivot.

Step 3: Step Three

Attach two 15" long beams

Attach a beam underneath the engine, and install blocks underneath that on either side. Drill holes through either side for the axle. Insert axle and and attach sprocket to axle or wheel then install wheels.

Step 7: Step Seven

Do the same for the front. Add blocks, axle, and wheels.

Step 8: Step Eight

Add a steering lever and throttle. The throttle lever is connected directly to the engine's throttle.

Step 9: Finished

Hopefully, I have given you a complete tutorial on how to build your own gokart. Some things on the Sketchup version may be slightly different from the real gokart, but the dimensions are accurate.

The axle seems to me to be the trickiest part of this whole build. What is it (hollow plumbing pipe?) and where did you get it. I can find wheels with bearings easy enough at my local Harbor Freight, but I am a little lost on how to get my hands on an Axle and needed brackets.
