Turning a base for testing a spacecraft
This was quite an unusual request from the Surrey Satellite Technology Ltd.
They required a large 700mm Diameter
by 250mm High base, with a 200mm dia. hole through the centre.

The base layer was to be mounted to the lathe, turned to size and a 200mm hole turned in the centre of the layer. Each layer had to be glued to the one beneath it while still mounted on the lathe. Then after the glue had set (24hrs) it was again turned to size and a 200mm diameter hole turned into it. This process was repeated over the six layers.

After the blank was laminated it was turned to shape, drilled with eight holes on a 298mm PCD, then sanded and given four coats of varnish.

The completed base was used to mount a spacecraft on, in order to carry out some electrical tests.
