O-roll Orchestrion plays the “Atlanta Rag“

I’m making progress on the O-roll orchestrion I’m building. I should have the top section installed with the xylophone, bells, flute pipes and violin pipes playing in a day or two. I made a new type of mandolin rail using .010“ mylar sheet and brass rivet caps with washers and I really like the sound of it. I also have the hammer rail pneumatic installed. Notice how Art Reblitz effectively uses the hammer rail to accentuate single chords. It adds so much to the performance!
