Spurred on by talk of compressor lines done in copper, i have plumbed in ours from the compressor, across the ceiling and put wall-mounted couplers along the bench. Copper pipe and yorkshire fittings seem to cope with 12 bar ok. Went round with the leak detection fluid, and had no leaks.
I put a temporary cap on one of the tails cos i was short of a coupler. After i had tested it i undid it while still full of air. jesus. 12 bar has some power. Soon cleaned all the dust out of the workshop!....
12 bar is great for making a blow dart gun, but i should have said that should i, cos in the news tommorrow there will be headlines, man shot up backside with blow dart gun. lol
