  • Cutting 5/32 aluminum tube(?)

    What would be the easiest way to cleanly cut 5/32" O.D. aluminum .014 hollow tubing into 2.25" pieces about 250 of them?

    Thanks in advance,

    Some of the big box stores have ''mini'' tubing cutters in the plumbing or tool areas. I am not 100% certian it will go small enough , but You might be able to modify to work.

      Find an archery shop or someone who makes their own arrows and borrow their arrow cutter/mini chop saw.

        I cut small tube like this allot. Chuck lengths of the tube in the lathe, 3-4 feet hanging out of the chuck, have a tool that we built, it's basically a pipe cutter setup on a set of hand shear handles with a stop on the end. very much like using scissors. once the depth/length is set it's like snipping string.

        Left hand steadies the overhanging tube, right hand using the tool. can cut 500+ pieces in an hours time with no effort. lathe spinning about 150 rpm. makes a clean cut, does shrink the hole a small bit on the ends, but we press the tubes into an item, then expand the ends to lock it in, so that's not an issue for us.

          Walter,

          Have a picture of it available that you can post or send me? Since you mentioned it, how do you expand the end? Have a picture of it as well? I was thinking about expanding the ends as well.

          David,

          Another good idea!

          Thanks,

            Smoke,

            I'll snag a picture of it today and post when I get back from the shop.

            We use the tube in these (note the end of the handle) As to the actual processes used for expanding and finishing I can't say. It's not something I do, I'm just a tool and die guy, not one of the knife makers =)

              Make a Dremel Chop Saw and put a stop on it. I think Marv Klotz made such a setup and posted it here.

              It is true, there is nothing free about freedom, don't be so quick to give it away.

                Smoke, here's the tool I mentioned earlier. It really does work like a charm, worth the time if your gonna be doing a lot of the little buggers.

                      How do you expand the ends of the tube? Have a picture?

                        if you want a clean cut on each end and you want it percise then id use a parting tool and keep it short just enght to make it thew and go past the length by about 2 or 3 thou and then face it to size after and you will have your 250 perfect shaped and cut to lenght peices ,, thats the way id do it ,,
