"Zinc Pest" on McCoy Trains

David NissenOGR Forum Member SUPPORTING MEMBERDIGITAL SUBSCRIBER

Many of the journals on the McCoy E2's suffer from "Zinc Pest". The side pieces
first expand causing them to bow out then eventually crumble. These parts are
cosmetic and are not a functional part of the drive system. This seemed like a
good first project for my new 3D printer. The photo shows the 3D printed part
which was then glued to the frame.

The next project was the small journal for the 4 wheel cabo ose.
