An engineering team lead by Graham Nicholas, including Alan Parkin, Richard Peck, Martin Shepherd and Terry Graham, has been established to reinvigorate progress with the cambox. The current design has been reviewed and we have started the manufacture a full-size 3D printed version. The aim is to fit the 3D printed assembly to the fabricated cylinder block to check all interfaces, e.g. valves, and driveshafts. The 3D printed parts will be great tools to assess feasibility issues for both casting and machining. With the exception of the cambox (the largest component) A1 volunteer Peter Scott is making the parts on his own 3D printer.
