Marvel Onkey Posted July 14, 2017 Share Posted July 14, 2017 How do people cut small tube without crimping it? I've bought some 1mm x 0.25mm aluminium tube to use as replacement gun barrels etc, but it is too small to be gripped by my K&S tube cutter which goes down to 1/16" leaving me at a little bit of a loss...

Pete in Lincs Posted July 14, 2017 Share Posted July 14, 2017 Insert some wire inside it and gently roll it back & forth under a new scalpel blade. That should do the trick. 6 Link to comment Share on other sites More sharing options...
modelmaker Posted July 15, 2017 Share Posted July 15, 2017 It doesn't do the blades much good but it really does work. Consider using wire inside a tube when bending a piece of thin tube, the same as a plumbers pipe bending spring 1 Link to comment Share on other sites More sharing options...

That should do the trick. ^This. Just mind out to keep the blade nice and straight, or it will start to slightly wander up the tube. I’ve found it best to do this on a cutting mat rather than a hard surface as the mat grips the tube slightly giving a bit more accuracy. The rolling effect of the blade may ‘mushroom’ the end of your tube giving you a tiny lip that you will have to sand off. 27 minutes ago, modelmaker said: It doesn't do the blades much good ^That. A thin cutting disc on a Dremel can work as well for cutting small tube. I stick the tube in a pin vise to make it easier to handle.

I found that I get the best results when I bend the tube very, very slowly. Pete Link to comment Share on other sites More sharing options...
Cheshiretaurus Posted October 22, 2017 Share Posted October 22, 2017 There was somebody demonstrating this technique at Telford last year, Think it was on the Albion Alloys stand. I had a go there and then and it was very easy to do. CT Link to comment Share on other sites More sharing options...
little-cars Posted October 22, 2017 Share Posted October 22, 2017 The JLC saw will do the job without a problem. They also product jigs if you need repetative cuts.... JLC Saws, jigs etc... Ta,Paul Link to comment Share on other sites More sharing options...
