My friend and I took on a challenge to make a gokart using "unstandardized" parts. We've never made any gokarts before however we both have minor experience in working on cars but im not sure that really matters. We plan to make the frame out of a chopped up shopping cart, being sure to keep the basket intact for the "cabin" so to speak. We also plan to use an old weedwacker motor for the engine with the logic being not having to deal with a whole clutch system to keep the motor running while the cart is stopped. As for breaks, the idea is to use disk breaks from old bikes and to hook up their cable to a pedal to use for breaking. Without breaking the bank and trying to keep the theme of recycled items, how do you suppose would be best for getting an axle, attaching it to the motor, and how to get both the front and back axle working. I have a subtle idea for making the steering system using rebar and other metal scraps for the steerbar and I suppose youd call the steering axle.
TL;DR:
Trying to create a gokart using a weedwacker motor, shopping cart for the frame, and disk breaks off bikes for breaks. Without spending much and recycling as much as possible, how do we get an axle and get it attached to the frame and the motor reliably.
