Electric Wooden Mini Big Rig

[GoDaddy]

Ok so my plan has just taken placed.
My son is obsessed with 18 wheelers.
So I'm gonna build him one before end of May for his birthday.
Motor and controller from Razor Go Kart.
Horn from mini spider-man atv.
Already got LED headlights\brake put together.
Blinking LED on ordered for turn signal.
$16 programmable USB sound ordered for startup/engine sound.
I just bought 8 10" pneumatic wheels on-sale $3.69each.

Since it's a free wheel, I will need help with modifying at least on wheel so it can drive.

Just be careful with those wheels. They are not meant for karts, and they break REALLY easy. They will not last you long at all. If you are going to be going REAL slow, they should be fine though

 

[cumminsbayou4x4]

i think those tires should be fine because it is electric

 

[GoDaddy]

Thanks for reply. Yea it's gonna be slow. Yea the rating on those aren't good, they flat easily. I'll probably get it seal or inner tube later if they flat constantly. You get what you paid for i guess.

So, any idea/help how to mount those tires to the axle?

 

[GoDaddy]

Wheels finally got here. Find out it also came with inner tube. That mean it wont deflate as quick as other reviewed.

So here's my first ghetto plan layout.

Now I need to go to northern tools to get 4 bolts hub to mount to the drive axle. I might go cheap way and drill a hole to lock the hub to axle.

Hope tomorrow is nice so I can go to Lowes and get some lumber.

GoDaddy- The issue with those wheel/tires is NOT whether they lose air (flat). The issue is that the bearings are garbage, and so are the hubs and rims. They are notorious for breaking apart on go karts, so we avoid them. IF your project will be going slowly (5 MPH or less), you'll be fine. At least then if they break, no one is likely to be hurt.

Doesn't matter. All the forces that act on a wheel whether your kart is gas, electric, or nuclear.

 

[GoDaddy]

Yea, I can tell they are cheap. They are not real rim, they are like 2 bowls put together back to back held by 4 screws.

Is it hard to remove the bearing?

 

[Doc Sprocket]

The bearings are easy to remove. Using a steel rod, (or similar) reach in through one side and drive the opposite bearing out by tapping the rod with a hammer. Then put the rod through the other side and drive the bearing out.

And then replace with some good quality high speed bearings...

Where can I get 7/8" rod for my axle? I measured the hub it's 7/8" without the bearing. I don't see any listed in NorthernTools. I haven't stop by local hardware store yet.

This is the bearing i'm thinking of using because of its lightweight.

 

[Doc Sprocket]

Don't use that bearing, the stamped steel housing is inferior to the cast iron type. Weight gain would be entirely negligible for 2 bearings.

Get your 7/8" keyed shaft at a good steel supplier.

I agree. Use one of these

 

[GoDaddy]

So I bought the block suggested above self align.

My issue is now my shaft is 5/8 and the motor/belt pulley from razor gokart is 7/8.
Is there an adapter? What should Google for: is 5/8 belt pully correct term?

So far budget:
8 Wheels and tires = $40
3 3fter 5/8 shaft/rod = $12
2 pillow Bock = $18

cool progect. Drilling the hub to bolt it to the axle will be fine. Youll want to make the non drive axle so that it just floats so you dont loose traction over uneven ground. good luck finishing before the end of may! I wouldnt worry about the bearings till they break. youve got enough work to do for now

 

[GoDaddy]

I'm having a little issue. I can't seem to remove the shaft from the bearing. It has a ring that locks into the groove. So now I'm just searching for belt pulley with 5/8 bore and a belt instead of wasting my time trying to get this thing out. I think they must have special tool to take this out.

 

[souperman000]

Got any pics?

I believe that "ring" is a snap ring or retaining clip, whatever you want to call it; with a screwdriver or some needle-nose pliers, you should be able to pop it off.

 

[GoDaddy]

weeeeh, finally got the motor, belt, pulley, brakes apart.
Tomorrow will be framing day.

 

[GoDaddy]

here are my little updates. Little thing at a little time.
The belt, the pulley and motor was perfect spacing.
I was afraid the belt was going to be too short.

Now, I was wondering if it's ok to drill a hole thur the rod/shaft to mount the wheels.
I don't want it to weaken.

Is that 5/8th rod? I wouldn't drill it. You might try making a hub of sorts out of a split locking collar.
