some of the tiles inside the torus
Bloody horrible graphite/fibre mix that was a complete pita to machine.
Took over machining the facing plates on the diverters at the bottom too, previous guy to me kept asking for more material because he had'nt been supplied with enough in the first place.
Turned out he was altering the stock delivery cards and hiding the plates he was scrapping..
Ahhh the joys of making nuclear stuff... see icon
PS we found all the 'lost' plates behind the tooling cabinets when we decided to move everything around one day :)
