Hi There,
I have a need for an air supply of about 300 psi and quite a lot of cubic feet too. It's for starting an old engine and using a descaler and I have been using 2 old refridgerant cylinders which work OK but are 20 years old. I have a Bedford lorry compressor.
I do have an old acetylene cylinder that appears much heavier construction and I have emptied all the charcoal out and inspected it and it looks OK. How much should this safely cope with and how could I verify it up to a certain pressure without too much danger of loosing it? I have an oxygen cylinder which is obviously very able to stand any pressure I could muster, but it's the wrong shape!
Any comments welcome. Thanks, George.
