I built the ten transformers from styrene sheet with the intention of hiding the lighting LEDs underneath; hence their need to remain hollow.
These were a tedious bitch to create. In hindsight I would probably have made one, then cast it in resin to make duplicates. Live and learn.
Time to test fit all existing parts on the earlier prototype resin ring (to avoid scratching the final ring)….
The transformers have a total of 80 tiny screw in the sides. I couldn’t find anything small enough so I experimented with carving my own using a template. I carved some brass into the shape of a tiny screw then heated it with a soldering iron and pressed it into the styrene. Took a little practice considering the scale.
