Cobs for Roller Organs
By Ed Schmidt
A few issues back, someone was inquiring about making new cobs for the Roller Organ. A few years ago one of the members of MBSI was considering doing this project but I never heard any more about it. I have lost his name, but I think he was in California. Over the years, a number of us have looked at this project, but all have put it aside. I went as far as getting the patents on the machine that manufactured the cobs. I looked for it last night, but can't remember where I filled it. The patent is very instructive on how they did the job. They used a master roll that was three times the size of the finished cob. In the master, they inserted pins to indicated where the pins would be driven into the wooden cob. This template drove a nailing machine that was fed from a coil of wire. When a pin was driven into the cob, it was cut off at the proper length. The top of the pin was cut flat while the free end of the wire was cut at a bevel so that it could be driven into the cob. The project hinges around a simple nailing machine.
Good luck.
