Sorry for the slow reply.
Good to hear you got the kart made. Did you manage to get it built in one
day? You done well if you did. With them 4x4's it must be a good sturdy
kart. A tip is to prevent the wood from getting soaked wet, as it would
add a lot of weight onto the kart.
Aye - I have an old motorbike helmet I use for going round on my old karts
) That and a good part of gloves will save many weeks of recovery! I have
often thought of putting some roll bar/cage on my karts, however I wasn't
sure if they would take the punishment and just give a false sense of
Thanks for the tip on the steering stops. I should add that into my own
wooden-kart plans as it would save injury to some other people. The levers
idea is good and definately something to try out. I had often thought of
setting up a "tiller" arm to steer a kart. Basically it would be a
rod/tube in a L shape connected to the front pivot bolt.
Anyways, Im really glad you found the plans of good benefit. Thanks for
the tips and ideas for improvement. If you get some photos of the kart, I
would be interested in seeing them, and can share them on the kartbuilding
website to help other people out.
Best of Luck,

The steering is VERY quick and as I started to gain speed, I was worried I'd roll it with the quick steering, so I went to drag my feet a bit to slow up. BAD IDEA! AS soon as my feet hit the road, they were pulled under the car, flipping my onto my face and hands. Not pretty. Next thing to do was... PUT MY SON ON! ;-) He went from a much lower starting point on the hill, started to go and whipped a sharp turn so quickly he threw himself right off.
