Hi John,
i can chip in some information ... I did some parts for radio controlled models and for my business. I am using an old medical suction pump (about 40 litres per minute and -90kPa). Works fine for getting the air out of the resin and the vaccum for the mould ... and i got it for free!
There is a very good "How to" handbook from a german resin distributor, the website and the handbook is also available in english.

and the handbook ...

Think this will be a good start ... and the materials will also be available in the uk.
The company is located only 100km away from my home ... if anything special is needed give me a mail!
