Nice job on that. Sounds good, how is the whole thing comeing?

just got more steel tubing for the steering shaft, steering shaft support, and roll bars, gonna get started on those as soon as my dad has the time to do more welding,

the weld connecting the wheel to the hub just broke, which means plan B! (which is my previous post)

When a weld breaks that easy you can bet it's due to no/little penatration of the 2 metals being joined together. You should wire brush the old welds, line the broken welds back up, reweld the hub to the rim. Remember to check for discoloration/slight bit of rippling in the metal on the other side of the metal being welded.

You MUST have penatration for a weld to hold!!!

Looking good sofar. Decide on paint color and sceme yet? Let me sagest medium to light Brown with fine Silver metal flake. I seen a Chevelle painted that way and instently liked it so much when i get the money to paint my van, guess what it's gonna be? Do you give up??? Thats rite, Light Brown with Silver metal flake!

ok, Well its drive system screwed up, we hauled it up stairs into the garage to ride it for the first time, we were on the road and when I pushed down the throttle, the sprocket broke loose from the weld on hub, this is caused by a really bad weld, it has been re-welded but and tested (to about 10 kph). i love it! i went around and let my dad try, then the chain fell and we just left it in the garage until tomorrow.

My 3 control systems are done, but the brake and steering are very very primitive. The steering relies on 1/16" wires that are begging to be broken (some braides already breaking) , but I have already got most of the parts needed to upgrade that to something more solid. The brakes is a single V belt wrapped around a pulley on the axle (FYI, doesnt do shit all), controlled by a wire hooked to the pedal, I need some money before getting disk brakes, or at least 2 pulleys and have the belt on a metal strip, or I can get scrub brakes, but that will take work and time, and school is only a week away. had some trouble with the throttle, cable needs a covering, too much rubbing going on

[WOW!!]

Sounds good. About the welds, I am not saying you cant weld but since you said the weld broke try tankeing some flat bar and setting it across the joint and welding it on there so it gives you extra strenght. It would look sweet with that paint and some diamond plate on there and some ghost flames. Good job.

i just noticed that the axle is bent, which is why the chain wont stay on, so i just got another pillow block bearing so i can keep it straight
