Just read your Entire thread, the work you are doing is awesome. I saw the diorama on your other thread with the cool hot rod and loved it, now I fully appreciate it. I thought I recognized the parts for your shop heater so, I showed them to my wife. She said they are cassette holders they use in the medical lab. Neat idea! Everything is really looking cool, makes me want to do a little more work on my garage. Thanks for sharing.
