Each Windcheetah is hand made and assembled by a dedicated team
of craftsmen engineers. We start with some straight lengths
of aluminium tubes. These are cut to length and the main tube
is machined along its length to provide a precise fit for the
centre casting which forms the heart of the cruciform chassis.
Production tolerances for the glue system we use are typically
as low as 0.003" so great care has to be taken
to ensure that components are produced to this level of accuracy.
The main tube then has the two bends set into it with a hydraulic
former, and all the tubes are highly polished before being sent
for anodizing. The pre-polishing is time consuming but helps
to achieve an outstanding finish on the tubes. Whist this work
is going on the castings, or lugs, are being machined. Each
Windcheetah has 14 cast lugs in its construction. These are
made to our specification and design by a local foundry. They
are hand made by a sandcasting process. Once we receive them
they have in excess of 140 precision machining operations carried
out on them. After machining the castings are hand fettled and
sent out to be powder coated. We use a high specification polyester
surface coat, the colour options are chosen carefully for their
excellent pigment retention. A lot of our machines are used
in hot climates and this resistance to colour fade is important.
At this point the collection of tubes and castings is issued
with its brass serial number plate. This number connects it
to the relevant customer order and becomes the machines identity
from this point.

Batch
of Windcheetahs for the German market |
Whilst these various production stages are being carried we
will be making the various special components that are required
for final assembly; axles, track rods, pulleys etc. All in all
there are approx 60 specially made detail components in a Windcheetah.
The finished castings are then bonded to the tubes to form the
chassis. Each chassis is cut to length according to the customers
measurements. The bonding methods we use are a combination of
thixatropic epoxy type or anaerobic systems. These give a bonded
joint strength that is as strong as a weld. Curing takes up
to 24 hours and the chassis is held in a jig to ensure perfect
alignment during this process. All internal lug fitting is achieved
by hand reaming the appropriate tube to ensure that all bonded
joints are within tolerance. The brass serial number is bonded
to the main tube.
The chassis is now placed into an assembly stand and built
according to the customers order specification. Accessories
are fitted at this stage as well as the specially built wheels. Transmissions
are carefully set up and adjusted to ensure perfect gearchanging.
Finally the moulded carbon fibre seat is fixed to the machine
and the Windcheetah is taken on an extended test ride on the
quiet country roads near to the factory… it's a tough
job, but someones got to do it!
Once our final quality checks are done we remove the seat,
wheels and kingpins, swathe the Windcheetah in layers of bubble
wrap and pack it in the box for despatch.
