That's a very interesting page! I've used some of those things myself but there's still a lot of suggestions I can try
ps. the blister-pack that my hay fever tablets are supplied in make good 25th scale bulkhead lights if I add four loops of thin wire, two vertical then 2 horozontal (and can contain a small white LED!) and I've found that the plunger from an insulin syringe is just the right diameter to force lubricant into a propshaft.....right now I'm looking for some discarded lengths of a broken GRP fishing rod to make scale (but not fragile) masts...

Hi Joe, Thats one of the best articles I have seen posted anywhere.A load of very practical ideas. Wishing you more strength to your arm for future gems ( I will raise a glass (or two) to you tonight) .Cheers, Walter.
