    Narragansett Machine Company speed bag platform help needed

    Hi picked up a Narragansett Machine Company speed bag platform which is in very good shape other than the adjustment wheel is stuck.
    There is a little play in the wheel and the cone shaped sprocket, but no other movement in the screw shaft or the bearings. I tried Kroil, no luck. I tried to move the screw shaft with a pipe wrench wrapped in leather, nothing.
    I could use some help.
    Here is a few photo.

    You could try hitting it with a torch. The expansion and contraction can free up the metal sometimes. Electrolysis tank if penetrating oils and lubricants aren't working.

      Whoa! That's a collectors item. They don't make them like that anymore. I hope you get it to work. Sounds like Bagger Pete has some wisdom on this.

        Can you tell if the platform brackets themselves are free on the support tubes? If the set screws have been over tightened that may have galled the tubes making adjusting it difficult, if not impossible

          Dutchman,
          The platform brackets (the knobs on the sides?) are free.
          Knobs and their screws are perfect! The entire platform is very near perfect, just stuck.
          It just makes me want to get it squared away that much more.

            Tried some heat and more Kroil. Still stuck. Which I knew how to take the mechanism apart to rebuild.

              Give some "Liquid Wrench" a shot at it. Make sure you let it sit for awhile then respray again and let it sit awhile longer. Good luck

                After looking at the photos of a restored one, to refresh my memory, the handwheel is probably held in place by a set screw. If you can remove that then you should be able to start the disassembly process. I don't think it's a press fit. Soak Kroil around the shaft then gently tap it our using a wood block as a buffer. You do not want to hit metal on metal when removing it.

                  Dutchman checked for set screw, looks like they used taper pins to mount wheel to platform.

                    Should be able to use a drift punch and a ball peen hammer to remove them, and work the hand wheel off the shaft. Then shoot some more Kroil into the bushing. If you can't work it out by hand, use a block of wood and a mallet and tap on the now exposed end of the shaft. That should free it up

                      Guys I am stuck. I can't figure out how to get it unstuck. I have have to move on and finish my drum which I will attach to a Balazs pro platform for the time being.
                      I can come back to this platform in the future. If any of you have any suggestions how to fix please let me know.

                        Hate to say it, but you might have to take it to a good machine shop to rectify the issue, not an inexpensive proposition.

                          If it is rust that is making it stick I would suggest making a electrolysis tank. It's easier than you might think. It won't damage the metal either. That platform is sweet, Good luck to you

                            This fall I will give it a try. Thanks for the suggestion.

                              Spent the last 5 weeks spraying penetrating oil in the moving parts of the stand. Yesterday it broke free.
                              Now on to refurbishing.
