Meanwhile, I've already gathered some parts. Engine, torque converter, pit bike wheels, tires, leaf springs, and some unnecessary gauges for the look. I've already spent £560

. What's the maximum a cycle kart should cost now?
I've also enrolled in an evening course in turning and milling. I hope to be able to make some things there.
I've seen that Gemini, among others, sells rear axles. Now I'm wondering if anyone makes these axles themselves. I think it would be a fun thing to do in the evening classes. Hopefully, someone has some tips on this.
To be continued.
