[Kartbuilding] Wheels for the Wooden Go-Kart

[Stephen Burke]

Hi Stewart,

Great to hear you're getting on good so far with the lawnmower engined
kart. Getting all the bits together is the hardest bit.

You can easily use plastic wheels (well wheels with a plastic hub) for
the Front. These wheels just spin freely on the axle.

The Rear wheels are a little more important. The rear wheels must be
fixed and attached to the rear axle. The engine via the drive-belt turns
the rear axle, which then turns the rear wheels.
You have a few options:
1. Try and carefully drill out the center of the rear wheels so they fit
tightly onto the rear axle. You then ideally need to weld the rear
wheels to the rear axle.
2. You could try and file/grind down the ends of the rear axles, so the
wheels fit on.

If all else fails, you can use a plastic wheel for the rear.
Drawing 14 on

shows how you can "sandwich" the plastic rear wheel between two metal
plates, so it will all turn as one.

I hope this helps. Let us know how it gets on.
Best of luck,
-steve
