Reply to ""Zinc Pest" on McCoy Trains"

The Steam Chest on the McCoy steam locomotives is another part that suffers from
"Zinc Pest". Attached is a picture of a steam chest that is starting to show signs of
"zinc pest". Also attached is a picture of a part that I machined from aluminum for
my own use. I spent 40 hours making this part. At the minimum wage of $15.00/hr that
comes out to $600.00 to repair a locomotive that I bought new for about $250.00.

If I need another part I will try a 3D printed part. I have made a 3D (STL) file for
this part (see third picture). I am going to print a test part to see if it looks
promising. If anyone else would like to try printing this part, send me an email and
I will send you the STL file. Just let me know how it turns out and what printer and
what material was used.

Another nice part - does it make sense to design the steam cylinders into the single part and print all of it? You do nice work Dave
