Well it works... but not the way it should. I should have made the top rotate on a tiny rotater and the bottom a huge slider. Instead of the other way around. This will break over time. I'll do it the right way for other ones. If I can think of a way to fit a rotated in the top. I might have to go buy some more tube and rod, I'm out of all the small size tube.
Took my airbrush with a .05mm nozzle (large general purpose) and 75psi with 9 parts laquer thinner to 1 part mineral spirits and blew all the paint off. Bad idea... too much laquer thinner it melted the plastic a few microns down. It didnt do any noticible damage but if I had touched it it would have got fingerprints and it might be slightly glossier now until I spray it. Going to spray it from a disatnce to try to get that rough look almost like powdercoating. I've never had to simulate deck planking before. I'd be better off buying some of that flat roller painted train decking for building 1800's train platforms.
I could always cut the deck out and replace it with flat stock styrene.
