      After a few months of all sideswiper sending, my bug has again caught
      my attention. It is a 1953 Presentation, my favorite bug so far.

      A friend told me Vibroplex will replace the contacts. I just called
      Vibroplex and they said it is $40.50 to replace each contact on the
      contact post, the contact spring, and the sliding dash contact.

      Is that service worth the money? Or can I do a similar repair on my own?

      Buy a contact cleaner from Vibroplex or make one yourself out of a sheet of 800 grit (fine) emory cloth doubled back on itself and glued and cut into strips -

        Buy a contact cleaner from Vibroplex or make one yourself out of a
        sheet of 800 grit (fine) emory cloth doubled back on itself and glued
        and cut into strips - about a dozen from a 75 cent sheet of emory
        paper.

        Refinish the contacts yourself.

            $40.50 is the total price wo/ shipping. It includes replacing each post
            with a new contact, the contact spring, and a new sliding dash contact.
            I just called Vibroplex again to be sure.

            The real question for me is whether my post contacts really need
            replacing or if the fine grit cloth will work as well. I have used the
            grit in the past. I probably depends on the shape of the contact
            surface. All of my scratchy sounds are ONLY dot related.

            I have used Flitz metal polish before, but have reservations about it.
            Flitz is supposed to prevent further oxidation. Wouldn't that leave a
            film on it?

              Steve,
              I just looked at the Vibroplex page and the 40.50 price is for all the
              contacts. If all of yours are a wreck (??) and you need them replaced,
              that price doesn't seem too bad. However, David's suggestion is a good
              one. Those contacts are pretty thick and should last quite a number of
              years, even with heavy use. Getting the old ones smooth in the event a
              previous owner took a file to them (or other drastic measures). Good
              luck.

                strips (from Ebay) and they do a great job. I also installed a
                capacitor across my key contact posts and that has made a nice
                difference in the scratchy sound. I used a .01 microfarad cap from
                Radio Shack, and installed an "O" clip on the ends to keep it in
                place without having to worry about it dropping off during hook-ups.

                If the contacts are ruined, they can almost always be restored. What you need for that is a flat surface to put the fine crocus cloth on. (In my last email, I

                  If the contacts are ruined, they can almost always be restored. What
                  you need for that is a flat surface to put the fine crocus cloth on.

                  (In my last email, I called what you need "emory cloth" by error, the
                  abrasive is the same but when it is put on paper, it is caled emory
                  paper and when it is on cloth it is called crocus cloth).

                  Disassemble the bug, and CAREFULLY rub the contact (face down) in a
                  figure-8 pattern being careful to press down on the center as to not
                  round the contact (not really a problem as long as it is uniform).
                  Another method is to cut a band of crocus cloth and wrap around your
                  finger like a bandage and "massage" the silver (towards the finger) in
                  a figure eight pattern.

                  If it is extremely bad (which it isn't) use course crocus cloth for a
                  few wipes, then medium for much more and then fine. The idea is to
                  level the surface, then with the fine cloth to polish it.

                  Clean with denatured (or rubbing) 90% alcohol. and let dry, then work
                  on the other three contacts.

                  Then when all is dry, polish with Flitz. It has an ingredient which
                  bonds to the silver to prevent tarnish and is excellent for contacts.
                  Clean by rubbing off with cotton pads or cotton puff. Do not use
                  paper towel - or use cotton tipped swabs with caution - avoid scarring
                  by directly hitting the wooden stick of the swab.

                  Paper towel should not be used on any mirror surface, just glass
                  cleaning microfiber, Turkish towels, cotton balls or fleece.

                    After a few months of all sideswiper sending, my bug has again caught
                    my attention. It is a 1953 Presentation, my favorite bug so far.

                    A friend told me Vibroplex will replace the contacts. I just called
                    Vibroplex and they said it is $40.50 to replace each contact on the
                    contact post, the contact spring, and the sliding dash contact.
