I was pottering in the Petrolhead Brewery last night and my eye happened to drift into the Petrolhead Garage. This is in a different part of the 10' x 8' workshop complex squeezed between the Petrolhead Joinery and the door. Behind various vital pieces of kit, that haven't been used recently, was my Oxy Acetylene set with an empty Acetylene bottle and whilst I was kicking myself that I didn't get a refill when I collected my CO2 bottle the penny dropped....I have oxygen for my wort. Happy days. Off to get the stone thingy from the goldfish bowl.
