I
am developing the prototype Ordinary (aka Penny Farthing, Hi wheeler)
for the Oamaru Ordinary Cycle Club as pictured above. It has an open
head design based on an original Victorian Ordinary.
In
the course of development in trying to make an affordable Ordinary it
has been difficult to track down certain supplies so I have engaged
manufacturers to supply those items.
There are some parts that require specialised equipment and the skill
to operate such as lathes and milling machines. Often builders do not
have access to this equipment but do have equipment such as a drill,
grinder and a welder. The parts below have the machining done and allow
you to progress and build with equipent more typically found in a DIY
garage. I have kept away from using castings. Prefering to fabricate
from steel. It is much easier to join steel strip with electric arc or
MIG than a casting. Acetylen plants allowing brazing are much less
common these days due to high rental costs of cylinders for home users.
The cost of MIG welders is very reasonable these days and one can use
gasless wire or own a carbon dioxide bottle that is cheap to fill.
The open head design of the cycle at the top of the page was built
without the use of castings. The design itself based on an original
Victorian cycle in a New Zealand museum.

The Ordinary Cycle uses a solid rubber tyre which is cut to length to
suit the size of the rim.
There are two types of rubber.
A wire
spring moulded through the centre of the rubber. The tyre is cut
to length and a few turns of the spring exposed by cutting back some of
the rubber. The ends are then screwed together and the tyre mounted to
the rim. Tools required...Pliers and a knife
The second option
provides a hole through the centre of the tyre. A length of 8 gauge
wire is fed through this. The wire is then tensioned and joined by
brazing. Tools required....Wire cutters, hacksaw, wire-tensioner, blow
torch, ezyflo brazing stick and flux
The first option requires fewer tools but the tyre can cost considerably
more.
