Weston made many contributions in fan writing, fanzine editing, convention-running and in local science fiction clubs.
He produced the first issue of the science fiction fanzine Zenith (later Speculation) in 1963 and he edited the Andromeda series of original anthologies from 1975 until 1977.
He later chaired Seacon '79, the third Worldcon to be held in the UK, and in October 2008 ran Cytricon V at the George Hotel in Kettering, a sequel to and commemoration of the event at which the modern British Science Fiction Association was created.
[4] At the last, a surprise ceremony was held, inducting him and fellow science fiction fan Rog Peyton into the long-dormant "fannish" organisation the Knights of Saint Fantony.
Since 1984, the Hugo Awards (modelled in the shape of rockets and presented at the annual Worldcon) have been cast by the car-parts factory which Weston owned and managed until he retired.
