Difficulty fitting tubing on discharge port

[Frikkie]

Someone sent me a set of 'Spin Swage' and 'Spin flare' tools from the USA but I guess they would be available in Italy. They work with a 18v battery drill and they're very good. They have several advantages to the older type flaring/swageing kit such as you don't need a clamp to hold the pipe and also they spin fast enough and make enough heat to anneal the pipe as they go. I thought they just a gimmick kind of tool when I first saw them but I've been surprised how much I've used them and how well they work. The only disadvantage I've found with them is that they can leave small filings / swarf in the pipe after use so you need to angle the pipe downwards before use or be prepared to manually clean the inside of the pipe if it's horizontal.
