  • fish-mouth tubing

    What is a good, accurate way to fish-mouth round tubing? I have a variety of tools including a drill press. Thank you

          If it is small enough I use a hacksaw and file, like these guys

              Just like the Bandsaw technique


              .




              .

              Ok, you put the stock in at an angle, cut the stock, turn it around and cut the other side at the same angle. It is like trying to put a point on the Tubing. You'll see what we mean when you make your first cut.

              There is a thread- I'll try to locate it.

                OK. I got it. Took a little while. Seems sometimes I engage mouth (or typing fingers) before I engage brain.

                  Works slick with 30 degree cuts. Some guys trim the points off, some leave them on. I makes avery nice T Joint. Somewhere on this site the table of what degrees fo what angle, etc., but for my non-critical welds a yardstick and chalk have given me enough 'eyeball' to put the joint in. All mine are non-critical, with no safety element involved....(unless it collapses on someone)...

                      Tube mitering program

                      Here is a program a lot of bicycle biulders use to miter tubing.
