I finished building the 3D printed Crank Organ.
It works!
I designed and 3D printed each of the pipes, as well as the tracker bar, the drive sheaves and the crank. I also 3D printed the gold decorative flourishes on the facade. The cabinet is wooden.
This is a 20 note organ which uses a standard tracker bar hole layout, so it can play readily available street organ rolls.
In this video, it is playing “Ballad of Davy Crocket”, a song on roll JSR-025 made by Pipes of Pan. All of the Pipes of Pan rolls sound great.
It took many iterations of pipe designs to create the sound I was looking for. I printed over 15 different pipe designs and trashed all of them, before finally deciding on these.
This Crank Organ is a great addition to the music room. The grandkids love cranking it and making music. I do, too. Plus it’s aerobic - cranking through an entire roll of 5 songs is a nice workout for your right arm!
