Player Piano Restoration - 1977 Aeolian with Plastic Unit Valves

I thought I'd share some of the steps I went through in restoring a newer (1977) Aeolian player piano with plastic valve blocks. In 1979 my neighbor across the street bought a new Aeolian player piano. Up until that point, I had only played restored old upright players and I have to admit the new Aeolian was a bit of a disappointment. It wasn't very responsive and pumping it was tiring. Based on that experience, I was confident I could make this customer's piano play better than when it was new by installing more traditional fiber washer and leather valves in place of the sponge neoprene punchings. If you're restoring a player piano, hopefully you'll find this video useful.
