    collars for dumbell

    Hate to keep repeating myself but they are not punch out of flat stock. These are 100% not die marks a die and punch will leave a sheared edge because that I what it does. As far as being cost affective when you double punch something you will always have distortion these do not show the "pull thru" And that means that if you did punch em you would have to flatten em. Making it cost much much more.

    Just sayin.........

      What is the point of this thread? The OP has never said if he is trying to make them or anything? Just trying to figure how these exact ones were made?

          I see. You would get better information if you would have asked for suggestions on how people recommend you go about making your own. Otherwise people were just thinking you wanted to know how those exact ones were made.

            What type of equipment do you have to make them? If you try to do them free hand I don't think you will like the results.

              I tried freehand oxy but the inner hole was too sloppy for my liking. I used large 50mm washers but they don't have the thickness I am looking for. I'm going to invest in a plasma cutter. Is it possible to use wooden templates for a plasma cutter? I can make them easily with a hole saw. Or would the plasma just burn the wood. I was thought how to weld, but notthing about cutting or drilling.

                They make circle burners for oxy/acet torches & also for plasma torches. The trick is to drill/pierce a starter hole to the inside of the cut line so you have a place to start easily without blow back.

                Yes you can use wood for plasma templates. They will burn after awhile but easy to replace. You can also use aluminum which cuts easy with a hole saw.

                  I use plywood templates all the time with my plasma. As mmw just said a starter hole is key.

                    The help I'm getthing on here unreal. I think in ireland they've imported that much finished product from china that the fabricating skills have been lost.
