Now, don't panic, no-one died, nothing went bang. I had a need to make a melting machine to melt some alloy scrap. My daughter had three old cylinders,way out of date, some rust etc. I needed 20 inch diameter by around 28 inch height, so I set to with the hose pipe and thin discs. Topped and tailed 2 of them, split one vertically, cut acsection out of the second to let into the other. This needed some porta power action, big hammer etc. Now I'm normally very good re ppe, and I did thinkI should have been wearing gloves. But the point was brought home when the ram slipped and the rolled steel cylinder sprang back, taking about an inch of the skin off my little pinky. Ouch I said... Pics of the melter to follow, it's a welded cylinder, pivot tubes and tilter welded on, waiting for bottom and top metalwork.
