    Default Cutting metal tubes to size

    Hi All,

    I've found a source of 3mm metal tubes which will take the 1.8mm standard inner tubes (Sean Stanton's tubes, future fly etc.). I was using cut to length tubes from McHardy's but don't like the inner tubing. I normally use a razor blade to score the tube and then snap off at the point of weakness and file off the burr. However, there must be a better and cleaner way to cut the tubes. I saw something from B&Q for small tubes (used for home plumbing). Anyone have a good recommendation for a cheap tube cutter - I haven't got much space and don't have a DIY bench. Just looking for a cleaner and easier way to chop a tube to length - still will file the tube afterwards and then line.

    Any tips welcome.

    Patrick

    Not sure this would cut through the tube fully as the minimum diameter is 3mm but the inner diameter of the tube is 1.8mm.

    Don't bother with the screwfix own brand they are ****. Go for Rothenberger which I think are about 18 but cut through 3 mm no problem.

    I've had a similar one (the red one) for years and it cuts down to any size as the blade goes between the rollers

    The last lot of copper tube the( same as Veniards slip stream) that I bought came from a company that supplies spares for classic cars, they are called Woolies from Peterborough.

    Default Cutting Tubing

    I have a small tube cutter but found it difficult to make it work with small diameter tubing. It also put a lip on the internal rim of the tube which reduced the diameter and needed to be filed off - perhaps I bought the wrong one. I now settle for a small desk vice and a junior hacksaw which gives a good result. Then neaten up any rough ends with a small file.
