I thought you'd find this thread sooner or later! A friend had a PIK 20 and we used to bet on who could come in the shortest...real nice plane and I know you miss it as much as I miss the -18. Just gotta love those 90 degree flaps.
Back to the build, I finally found some time to continue along. The pics will explain everything but I want to say that if you can get ahold of some newspaper or printing aluminum sheet (lithoplate), do so. I got mine a number of years ago and perhaps with the computer printing done today it's no longer available. I guard my stash jealously but am known to share if someone really has a good use for it.
What's so nice about it is that it's easy to work with (can be cut with household sissors) and has a spring to it so when it's formed it stays that way. I use it in lots of places in scale building and it makes great hatches, cowl parts, etc. etc. An added bonus is that one side has a coating that's similar to a prime coat and is easy to mark with a pen.
