  • Pipe bending

    Does anybody have any idea of how I could make a jig or something to bend 2 1/2 inch pipe for pipes on a truck without having to spend a grand or more on a bender any ideas, pictures or thoughts would be helpful thanks..

    What are you trying to make? What degree bends do you need to make? Are you going to be bending pipe or tube, they have different OD?

      If your doing a once in a lifetime project, when you factor the cost, and learning curve of a bender, youd be money ahead to sub your bends out.
      Caution!

          Sounds like he's trying to make an exhaust system? There are plenty of on-line sources of pre-formed parts; just buy a bunch, and cut/fit/weld as necessary.

          I know this, only because I've been searching the web the last couple days .... a friend of mine just bought a truck, with the catalytic converter removed ... apparently, a new law, just took effect, makes 99% of all replacement catalysts illegal here; they will not even ship to California. But in my various searches, I found you can get mandrel formed 33's, 45's, 90's, 180's, in whatever diameters you desire.

            I agree, You may be ahead to job out this one We all are tool poor. Money is hard to make anymore so sometimes better to job it out or even turn it down. Most Benders plus dies are alot of money. Well good luck would like to know what you come up with.

              I'm. Trying to make exhaust pipe and I just wondered if there was a way to make a jig for a 90 and maybe a 45 so I could do it myself I'm looking at getting a new 140 millermatic for Christmas so I was just gonna see if anybody has ever attempted to bend it before or if there was ways to do it without a machine thanks

                Ive been at this a long time, by hand? Never seen it, cut wedges, saw cuts, maybe, but really not worth the effort!

                  I would just buy what ever you need from a place like this http://www.spdexhaust.com/BendsB.html and then cut and fit and weld it all together. With a little googling you can probably get the bends you need for a decent price.

                    I actually do it on 2 inch all the time, I use sawzall and am really proficient, takes just a few minutes.
