  • Swivel Question

    Can anyone tell me what’s up with this Everlast swivel? What is the black part of the base? Is it rubber or plastic, and did this design come before or after the all metal version of the swivel and why?

    I have that one. The black base IS plastic and of course the rest is metal. I ended up spray painting the black to silver to make it look to be metal. #OCD Dutchman posted something not long ago about the plastic base but I've no idea what thread that may be in and I don't want to guess on what he said. Plastic base seems like a money saving ploy on Everlast's part. ?

        Sad how? Because it has a plastic base? I owned the all metal version of this swivel, and it performed well. However, it was a little noisy. I’m wondering if maybe with this plastic design it is quieter than it’s all metal counterpart.

          It was reduction in production expense. The flanges were originally castings that were machined. It was less expensive to make the flanges out of Delrin, with an injection molding machine the number of steps were greatly reduced. https://www.dupont.com/products/delrin.html

              Is it a durable plastic material? How does the swivel perform?

                I used it for about two weeks. Didn't have any problems at all and performed as a chain link normally does. Keep in mind, I'm not a chain link guy. I just have it in on my swivel collection board.

                  Plastic Ballhook Swivel on a Board. Here is a classic video performance. I'd say it held up prettttty well. (start 1:28)

                  My own variation was to drop out the plastic ball and hook, (which tended to "float" and the screw would come out of the ball if you didn't superglue it inside,) and then put a steel ball and hook into the plastic housing. I loved that set up. Still do as it is very accurate with minimal "clank" of the shank on the housing.

                  Read the section down this page on the Plastic Ball Hook swivel.

                    The more modern plastic ballhooks like in speedbag's links are not Delrin. I believe they are ABS. Dutchman, what makes you say the vintage plastic base in the original post is Delrin? I ask because I would be surprised they would you such a high performance and expensive plastic on a speed bag swivel which doesn't require any of the special properties of acetal.

                      I've had a couple of these swivels over the years, never heard of any problems with the base (the male half, that's another story) as far as the threaded portion or the mounting holes. Delrin was/is used in the manufacturing of NMRA (National Model Railroad Association) design couplers. I had noticed that the properties in the material in both the base and the couplers were the same, or really close to it. Could the base have been made of something other than Delrin? Quite possibly, As I recall these swivels were made after the company had been sold and a large portion of the manufacturing was outsourced to China. It could have been made with a material with Delrin like qualities, but not necessarily Delrin (which wouldn't surprise me. Thanks for poking the old grey matter Rusty......

                        Now you got me scratching my head. Maybe I am full of it, and those modern bases are Delrin? I really didn't try to figure it out for sure. I could try to measure the density, that might help. But the surface doesn't feel, to me, very much like the Delrin I use in the Arc swivel (the white ball).
