Summary Not a lot of progress since early November! Hope to restart editing in New Year. Lots of material provided by JT. CB to edit to make consistent with rest. Intro provided by KL. Other sections written by CB (partly plagiarising PS thesis!). Most lack (sufficient quality) figures. Many sections not yet provided! Who will write “mechanical integration” section (frame, jacking system, services)? – I can write functional description. – Is that sufficient? Previously decided (I think!) to document design of last summer. Do we wish to update? – Review when present version complete? 3
