Front wheels - Start by cutting a length of wood (At least 3/4 inch
thick) to the length of the axle. The wood will need to be wide
enough to mount the axle and allow a hole to be drilled for the
nut and bolt pivot next to it.
Attach the Axle to the wood - For this you'll need to improvise
with what you've got (This is what kart building is all about) "
I have shown 3 methods which you can use in the picture below the
animation. The best method is the "U bolts" which clamp
the axle to the wood. The worst method is the bent nails, if you're
forced to take this route you'll need about 10 large nails to get
it strong enough. It helps if you can cut a groove in the wood for
the axle to sit in. NOW remember you have to get the nut and bolt
through, so the axle will have to be mounted forward of the centerline
of the wood. Drill a hole large enough to fit your bolt through
in the centre of the wood.
2. Back wheels - Use the same
method as the front wheels but mount the axle in the centre of the
wood this time for maximum strength. No need for pivot holes this
3. Main board - Can be any
length really but 1.5 times the length of your legs would be a good
ball park figure. It will need to be narrow enough at the front
to allow the front wheels to turn with your feet on them. You can
always make a cutout at the front of the board if it is too wide.
Mark out the centre line of the board to drill the pivot hole for
the steering. Before you drill the hole, position the front wheels
under the plank and get them far enough back so that the front of
the board protrudes a little in front the wheels. This helps protect
the wheels in the event of a crash. Mark the hole for the centre
4. Mount the front wheels -
The front wheels will be mounted using the bolt down through the
top (With a washer). Place a washer on the bottom then screw up
your 2 nuts. Not too tight here, allow the steering to work smoothly.
Using 2 spanners (Wrenches) placed on the nuts (NOT the bolt) tighten
the nuts against each other this will stop them working loose and
is essential if you want for front wheels to stay on.
5. Mount the back wheels - Position the rear wheels at the very
back of the wooden plank or at least behind your sitting position
for maximum stability. Make sure they are centre, then screw or
nail from the top down to fix them in place. Use at least 4 screws
6. Steering rope - This essential
item allows you to steer whilst you have your feet down as brakes,
as well as giving you something to hold on to. In normal motion
you will be steering with your feet of course. Attach it to the
outer sides of the front wheels just either side of your feet position.
It is best to drill holes for it in the front wheels then just knot
the rope underneath to hold it in place.
7. Finally make sure there
are no sharp bits sticking out anywhere and run some sand paper
over the wood to smooth it and
remove any splinter hazards. Off we go then!
