      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.

      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.

        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 ?
