123D Catch from Autodesk

I forgot to mention that 123D Catch is a free download. You just have to create an account. Meshlab is also free.

Looks good,

I will say You should not kink your welder lead cable like. That will(is already) damage the liner and give you the most difficult time welding as it also kinks the wire inside. Id also get a bigger(as in a bigger gauge) extension cord or weld closer to the source of power, that is looking for a fire to burn the house down due to that length coiled up like that.

Thanks for the advice. I didn't think about the extension cord. I will look for a larger gauge.

Rear Suspension

This is my "sophisticated" jig for welding the control arms.

A little late night welding.

It got kind of late but I have the rest of the brackets tack welded in place for the control arms. I used a piece of ALL-Thread to keep everything in line for the rear axles.

:lolgoku: Hey, it doesn't matter what it looks like, as long as it works

You seem to know your stuff; the design work & engineering going into this build is amazing, not to mention all the little "tricks".

Again, great work :thumbsup:

Ariel Atom Rolling Chassis

Finally have wheels on it so I can roll it around. I might have to push my son up and down the driveway in it a few times. He's been waiting quite a while for this.

Removing parts from the 3 wheel cart

These are some of the parts we are removing from the 3 wheel cart to use on our Ariel Atom Kart. They're kind of greasy and grimy but I think we will fit them on the kart first and then take it back apart and clean and polish everything. It's definitely going to need new wiring.

My wife knows how bad my son wants this done so she has been very understanding about the long hours I've been spending in the garage working on it.

Chain, Speed Control and Batteries

We added the chain and batteries and found a spot for the speed control. We bought the batteries last year so my son could ride the 3 wheel cart around the neighborhood. I think he will have more fun driving the go kart.

Wow this is quite the cool machine, I do like this. I just have a few concerns... please dont take this the wrong way, its just a little safety notation. I really mean this...
I didnt think this was going to be an electric machine. I just didnt read this that good. Not a problem....

The problem I see, is that I see there is some major welding issues. I reckon there is a fluxcore welder being used to construct this. Whenever a fluxcore wire is being used, you need to brush and chip after each time the trigger is pulled, without fail, to make a successful weld. Its like a stick but wire feed.

On your joints you need to have a more consistent bead of weld joining each part, you have several multi point intersections of tube.

I only go into this, And like I said it is cool and its a family project, is that..

The motor of choice is an electric motor, and they have a good amount torque instantly, that is the nature of there design. I just wouldnt want it to rip itself apart while at speed or potentially on a start or while slightly stuck.
There is chains and some flex joints to slightly move to dissipate/absorb the torque, but that will only go so far.
The motor itself I reckon it'll need more secure mounting(I understand your still in construction mode), but it still comes down to the structure itself.


So in conclusion, it is a cool project, not trying to be a debbie downer, but(IMHO) I think you need to look into you welding a bit more, before continuing on.
