Radio Flyer Go Kart

[robotmickey]

Couple friends coming over tomorrow so we'll see how much we get done.

 

[robotmickey]

So, made some progress...
Added a little instrument panel to under neath the seat and added the pretty aluminum diamond plate stuff. Also added a place to put your feet, I got the metal for them from our old ping pong table. Still need to paint it. Thinking about bed liner for the inside.

You have to keep that Radio Flyer red...its just iconic.

 

[robotmickey]

It is... but everybody's wagon is red.

can u give me a little more detail as how u did the sprocket on the live axle?

i assume its a #25 chain you u are using?

how did you mount the sprocket to the live axle?

is that a 1" axle?

 

[robotmickey]

It is a 3/4" axle, #25 chain. I used the weldable hubs from surpluscenter.com. What I did was:
The sprocket had a threaded collar on it which was how it originally attached to the scooter. So, fortunately and coincidentally the hub slide right into the threaded collar, it was centered pretty good, then I just welded the hub to the sprocket. I feel like I didn't explain it very well.

 

[cboy]

i think i got it....

this?

what kind of sprocket are you using? how many Teeth?

The one i have is a 80T with a 2-1/8" center bore

i'm wondering if thats close enough lol

 

[robotmickey]

Yeah, exactly.
My sprocket it a 90 tooth.
For the sprocket you got, you're going to have to make a hub withe the four bolt holes drilled in it, with a center hole of 2" so you can slide it onto the hub, and weld it on.

Unless you have access to a lathe, in which case you can turn down the first 1/4" or so of the larger part of the hub to make it 2 1/8" to fit your sprocket.
Again, I'm not very good at explaining things unless I have the piece in front of me point things out.

 

[robotmickey]

I added a chain tensioner because it was a little loose and really had no other means to tighten it.
I know there is a small hole in the frame at the top on the joint. It will be fixed. Also the axle looks distorted in the picture, but it is only the light.

 

[robotmickey]

Painted the wagon. I went with red so that you could tell it's a wagon, if it was black you might not be able to tell from a distance. I tediously masked over each letter with masking tape before I painted it. It probably took me five hours to tape over each letter and the little guy on the wagon in the middle, but I think it was worth it. Couple pictures:

looks nice!

where did you get the axle kit from? Im only finding 1" axles

thanks in advance you have been really helpful in me figuring out how to setup my kart

 

[robotmickey]

It wasn't a kit, I bought two 3/4" bearings from surpluscenter.com (the locking kind), then I bought an 18" 3/4" keyed axle from bmikarts.com, but on that site they consider it a jackshaft, not an axle, due to its small diameter and short length. Then I used the weld-hubs from surpluscenter.com which I centered and welded to my wheels, brake drum and sprocket.

 

[robotmickey]

Painted the frame and parts today, Veeeeeery close to being done. Just going to paint the rims. What color do you guys think? Red Black or White? I was also thinking about make the tires white walls with a red pin-strip.

 

[landuse]

You did a good job with the painting there. I also like how you engineered your chain tensioner. Does it work well?

I would go with the white wall tyres as well. I am just not too sure if the paint would stick to the rubber that well though.

 

[robotmickey]

Yes, the chain tensioner works very well. Yeah, it's all right if the paint comes off, as long is it looks cool for a little bit.

 

[cboy]

I would do red rims, and white walls....for the white walls use Krylon fusion paint..prep the tires by scuffing them up with a clean kitchen scubber and some alcohol, mask and paint.

krylon fusion is really good at bonding to plastics and should work well on rubber too.

 

[Doc Sprocket]

Looking Fantabulous!!!

 

[robotmickey]

Thank guys. Couldn't do anything today. FINALS!!! AAAAHHHHH!!!!! Tomorrow is my AP calculus final, which is really the only one I'm worried for. Wish me luck!!

 

[Doc Sprocket]

Good Luck! Yeah, too late... How do you think you did?

 

[robotmickey]

soooo close:
