Ok then
before i go off and do something else!
There is a way, you need a bigger photocopier! when i did the battletank i had to take the plans above 500%! Luckily next to me I have a large photo copy center .Look in the local google for photo copy center or drawing office or digital printers. My guys can produce plans that are AO in size , thats five times that of A3. The thing is huge! Dont bother with a kall kwik or the like , you need industrial size copiers. If you cant get anything local you could try ringing Dorking litho digital section ( in Dorking Surrey) post them the plans and i can go and collect and pay for them and its sorted?
happy to help
