The Pennsylvania Rail road specific brake wheel was scanned in a local train museum. I have a better structured light scanner as of 2016, but the example I was scanning had layers of shiny gloss paint making the scan difficult. The original was also bent so I only used a section and repeated it. I later found a drawing of the part… The parts for the wheel were cast in a low temperature rubber mold. The molds were made using 3-D printed metal patterns. The final kit developed for sale by the client is also pictured.
