Re: Cleaning copper gas tanks
I had two tanks in Grantala that appeared to be the original 1938 tanks. They were plated brass by the look of them, riveted and with vertical baffles. Plenty of evidence of repairs. I didn't trust them - and that is with diesel, not petrol (gas if you prefer).
When I removed the tanks - a difficult and very messy job, involving saws and air chisels, etc. they were full of mud at the bottom - at least a gallon of it in each tank. The crap had built up over 70 odd years - despite the tanks being fitted with drains. The tanks were a definite safety risk.
I was rather glad to get them out of the boat.
Carpe the living sh!t out of the Diem
I'd rather look back at my life and say "I can't believe I did that" instead of being there saying "I wish I'd done that"
