  • cart for my JD Squared #3 tubing bender

    Build this up this weekend. Just need to do a little finish work, then off to sand blast and powder coat.
    I wanted something that has all of the parts and die sets in one place. Going to get a die set for 1" square next.

    Nice job! How do you hold it down during use?

      Locking casters, but it doesn’t need to be.
      See the big screw hanging? That’s s lead screw out of a mill. So, the force is not really transferred to the stand. No need to be bolted down.

        Nice work as usual. Do you arm strong the lead screw or drive it with an impact?
        I just need one more tool,just one!

          I just use a socket and ratchet. The lead screw provides plenty of mechanical advantage. It will easily bend 1.5 x .125wall tubing.

              Nice work Sid,

              Could you show it in the operation mode? I'm not getting the concept of the threaded screw and where it does the work. simpleton here.

                T3- the lead screw is from a Bridgeport mill, 1.25" dia.

                I'm either going to find or make a ~24' ring to replace the socket and ratchet. That will make it that much easier to use.

                Mr. Fixit- I'll get a picture of the screw in place tonight.

                  Here is the set up with the lead screw.

                    Hi Sid,

                    Terrific ! I thought you had built the complete bender, but after seeing the picture with the JD Square stamped in the frame and the protractor, I now understand that you built the stand and the modification to use the screw for operation vs a manual lever I assume.

                    Thanks for the updated post.

                      Yeah, I did not mean to imply that I made the bender itself.
                      It's fairly heavy and bulky. got tired of finding a place to store it, then having to dig it out and clamp it in my vise.
                      The cart solves both issues.

                        How many degrees will the lead screw sweep?
                        Brilliant!

                            It will do 50* before you have to bring it back and move the pin to the next hole if you wanted to do a full 90* for instance.
                            I usually just zip that back with an impact. I like the lead screw a lot because it allows much better control that the lever system provided.
                            I'm not sure about a hydraulic set up. Certainly slower but I still think it might be easier to control.
