Hi from,
John Roberts the founder of Go Kart Daddy
Building go-karts has always been fun times. I used anything I could find as a lad growing up in Weymouth Dorset. 

Wheels were the biggest challenge and when you finally found  some there was the next problem what to use for axles. 

The old silver cross wheels were the best and very hard to find any that are not worn out these days. In 2005 We made a one page website offering free plans on how to  build a wooden go-kart based on my hobby interests. 

This quickly had great response, mainly about sourcing wheels and axles. 
I now supply wheels, axles, hand-brakes, complete flat packed wooden kits. All parts for schools, colleges, team building events and family fun days out. We are now able to offer a great range of pedal go karts from the worlds leading manufacturers BERG & DINO go karts. Plus wooden go karts from KIDDIMOTO
