Computer Aided Design Drawing of the Texaco Wheel as seen on Page 3 of the Sun.
Several visuals were produced in Rhino3D and e-mailed to the client, this is the agreed final design from which was produced the pattern.

By e-mailing the very same file which produced the visual, to a programme which interpreted the file, we then sent the instructions to the milling machine to enable it to produce this CIBA Resin pattern, which was then used to produce finished casting.

The finished Aluminium casting for use in treasure hunt promotion which were made by repeatedly pressing the pattern into resin bonded sand, to make outside-in versions of itself. Into these indentations were poured molten aluminium, producing, after some cleaning up,

An unusual project

Prototype Submersible produced for Aquatechnology Ltd

The body shell was produced directly from the CAD using stl data to make one quarter section and then taking silicone casting of the sla model and then making four castings to form the complete bodyshell. The prototype has four, two axis oscillating fin units. The four opposite units are mechanically synchronised and arranged to balance both torque and reaction forces. A single motor drives the whole craft. A change in fin pitch alters the thrust vector wherever it is on it's orbit. The fins sweep a large area compared to a propellor
