Brakes
Picture this, you’re
hurtling down the first length of the Soap Box circuit, wind in
your hair, goggles flying off – when suddenly you realise you’ve
got a problem. There’s a corner coming up and you’ve got no
brakes!
If you don’t fancy making
friends with a hay bale on the first corner of the circuit then
here’s our idiot’s guide to “Braking Systems”!
Simple Brakes
Braking Systems Using Bicycle
Brakes: Find an old bike with its brakes still
in good order and use as much of the braking system as you can which will
save you both time and money!
Find an old bike with the old style
of braking system – they will be more resilient and they are much easier to
remove from the bike and then attach to the soap box. You also have some
brilliant brake handles to go inside the cockpit for your convenience!
Making Your Own Brakes…
The More Complex Solution:
Pedal Brake Systems:
Now we’re going to let you into a little secret! There’s a favourite
braking method for professional soap box racers. It is a bit more tricky,
as it requires a pulley system to link the pedal with the brake at the rear
wheels. The brake arm must be lifted by a spring so it is held away from
the wheel until the brake wire is pulled tight by the driver with the pedal,
when they want to brake.
The Even More Complex Solution
Handle Brake System:
Now the pedal brake doesn’t suit everyone. If you’ve got
big feet or your soap box is going to have a small nose or it’s just too
complicated, then you may find there isn’t much room for your feet to move
the brake pedal. This will probably mean you will have to settle for a hand
activated braking system. This is where the lever is pulled up to the brake
pushing the pads against the back of the rear wheel. No spring is needed as
the handle counteracts the weight of the brake pad keeping it clear of the
wheel.
Steering
Car Steering:
Steering can be made from a
rack and pinion steering box out of a small car (minis or
old fiats etc.) and attached to your soap box axle. Finding
parts of old cars is probably the easiest way to begin
building your soap box.
You might prefer to
build your own steering system. There are two simple ways
you can do this, bicycle steering or string steering.
Bicycle Steering
The easiest use of a bicycle
would be to attach the frame or just the fork and sleeve to
the frame of your soap box and then keep the single bicycle
wheel at the front to steer with.
Or if you want to
have steering for two wheels at the front, weld the front
fork of the bicycle to an outer sleeve (metal tube) covering
the axle. The fork would need extra support to guarantee
success.
String Steering
This system is the easiest to create. It involves attaching
rope to both ends of the front axle. The axle should be
able to move freely with the use of a pin and sleeve
attaching it to the main chassis or frame of the soap box.
