Metal or wood?
should i go out a buy a mig welder and learn how to weld ( could be a usefull skill for fixing cars come MOT time )
or just knock up something rickety out of wood and pray it hold together?
anyone found any build blogs of metal carts?
still stuck on steering, although i have seen mention of using co kart stub axles
Thanks for the fishtailing info.. VERY useful!
although, the pic is not mine, its just a pic of one using the same chassis as i was thinking of using.. a sack truck.
i was thinking to go with x4 truck tyres all round.
im not too eagar on having tyres tooooo wide, as i think that might slow the cart down too much ( rolling resistance etc? )
the red bull thing would be great to enter, and i just might, but test runs will be done on the street. near me there are some brilliantly fantastic hills to do.
straight ones, steeps ones and technical ones.
hopfully might be able to get a mini race series going with some suicidal mates.
and its a perfect excuse to brush up those ( non-existant ) fabbing skills to use on other future projects
i like the wheels, and all round drum brakes on this one...
im guessing these are go-kart tyres?
and this looks.. umm complicated?
my intended chassis

Smallest tyre contact patch you can manage, so thin bike tyres pumped up way beyond max pressure
only problem with that option, is that im not planning on regualry running on prepped race track surfaces.and cornering grip and braking ablilty are quite important to me also.
do this on the public highway means, glass, sharp stones, speed bumps, potholes, sharp corners, road that end in T junctions or major traffic light controlled junctions
thats why if you look at the Undergroud vids, most of them have wider rubber, rather than skinnys, so that they can corner, even though it means sacrificing some speed.
i guess ill just have to have a selection of wheels and see what suits me best

£8.61 ea doenst seem like a bad deal
has a steel ballbearing too.. great. the plastic ones have brushings instead of bearings
Its also quite a flat profile. Im not so sure....
Thing is, yes its a flat profile... but isnt that what i would want for grip... the cart isnt going to lean into the corners.. so rounded rubber will never come into contact with the ground, and so just be wasted.. ?
