      The Codetrol has a mechansim like the Vibroplex.  It feels like a Vibroplex.  They were made in the early 1950's, I say, "They," were made, in fact, it seems that very few were actually made.  Eight are known to exist including the one I restored which was a prototype given to a telegrapher to try out, then, because he didn't really like it and it had never been actually finished, passed on to a kid.  I doubt if twenty were ever made.  I don't consider it a significant key, but a few collectors have chosen to pay handsomely for them (as in thousands).
       
      Yes, I think shipping aerosol cans has problems, but I imagine something similar is made there.  Like I say, try it out on a test surface to get a sense for how thick to lay it on to get the kind of wrinkling you want.  And remember, the wrinkling takes place over time, not immediately.

      Wow! what a great restoration job and what an interesting key the Codetrol is, I can understand your reluctance to see it go Fred, so does it work on the same principle as the Simplex Auto, releasing the pendulum or is it like the standard Vibroplex action but sideways instead? hard to work out from the photographs.

      That wrinkle finish looks great, I pick up the can from a local supplier tomorrow I hope but I doubt if it is the same brand as what you used, importing aerosol cans into Australia has some problems I thought I read somewhere, if this local stuff does not work out I will have to consider doing that if I can.

      Sadly these days any access to the electroplating shop that was part of the Reclamation Engineering business I was part of for 21 years has long gone, good platers here are hard to find nowdays.

      Thanks Fred, great web pages.

        Hi, guys.

        Something I tried way back when was to use different thinners with
        enamels. I used lacquer thinner once. I painted it on a panel and the
        rapid evaporation caused the winkle effect. After 3 or 4 days, I baked
        the panel and it became very hard.  There is another thinner that is
        used to speed up enamel "drying" and it is also used as the fuel for
        Zippo cigarette lighters, naphtha.  It needs to be accelerated with
        heat, though.  The wrinkle finish is caused by the rapid, but uneven
        evaporation of the thinner.

        Different enamel respond differently, so test on scrap first.

          G'day Joe

          I will be trying as many suggestions as I can, thank you for your's Joe I will most certainly try it, I got the spray can of crackle paint today from the Auto parts shop, it is a high temperature paint for use around engines, I dont know until I try how fine the crackle finish will be, there are a few ideas on the web about how to crackle paint, apparently Tung oil was added to paint too in the past but info is scant about just how the process went.

          Interesting times ahead!

            Another source of information would "OLD" ARRL handbooks.  I believe that
            is where I first read about doing the crinkle finish.  I had built something and
            the 19" rack panel was either bare steel or aluminium.  I have used that spray
            can wrinkle finish paint with good success.  It seems like it required a think
            coat, but that was awhile back.  Having worked in car and radio refinishing,
            I always enjoy learning and trying different methods, especially when try to
            restore an object.  I wish I could afford a small machinist lath so I could make
            some of these small parts.  Maybe some day in the future.

              Hello Wade ...
              I just measured the contact spring on my Simplex Auto and it is 1 & 3/4" long. Not 2".
              Also it is 1/8" wide ..... Perhaps just an adjustment of the movable
              dot contact on the pendulum would do the trick ?
