Mike T Posted September 10, 2021 Share Posted September 10, 2021 (edited) Thanks, Tim. The washer is a neat idea, but thinking about it, I can easily turn a top (or just a plug) from aluminium. Up-thread, Davey P mentioned Cu pipe. A while ago I used some left over fittings to make up a diesel tank. It's ideal for the test stand, but far too heavy to fly! (It was shiny when I made it...)

Dave Brooks Posted September 10, 2021 Share Posted September 10, 2021 For a lighter tank type setup I have used the small pressurised aluminium tanks that are used in inhalers. Unfortunately I have a constant supply of these. Cut down and then clamped together using a long M3 bolt and a penny on the open end with rubber seal. Brass tubes soldered in for vent and pickup. Easy and very light. Enough for 5 mins is so on my radio assist tomboy and DC Merlin. Quote Link to comment Share on other sites More sharing options...
