building a man sized kart

[MANKART]

I'm 6'8" 300#
I going to build a "man sized" stand up scooter/kart.
Think Zappy three wheeler.
Powerd by golf cart motor and 4 full sized batteries.
Golf cart wheels, Harley front. w/brakes.
Total GVWR +/- 700#
Question:
Will DIY karts/scooter parts be strong enough or do I need to use golf cart bearings, parts etc etc? I'm having no luck getting in touch with mini-chopper parts people. Guess they think I'm nutz.

I'm bigger than you, I used 1" axles from northerntool, no suspension, holds up great, I use it for offroad.. the batteries cause concern though, they add another 80-100lbs, plus the electric motors 30+lbs at least I'd imagine. if you use suspension that would help with impact loads.. I'm assuming for on road/pavement use, I would look at golfcart parts as they are designed for 400+lbs of people and the batteries and motors... if you use go cart parts, I'd figure out a suspension, or use balloon style tires. sounds like a fun project.

you might even think about going 1 1/4 inch for the axle even tho 1 inch would be fine.

I believe that the pillow bearings that are sold for the live axles are fine for that -- they are very stout.

 

[ironman]

i have a set of those they are very strong they will be used on the next project.do not look like they are cheap made.

Ohh yeah that pillowblocks can hold ALOT of weight. The ones i have can hold a couple thousand. The bearing can hold more weight than the shaft can even handle
