The motor is a governed speed mabuchi that I believe runs at 3600 RPM only. Most of the flywheels were made by me where the early ones were 316 stainless and then aluminum. The clamp is mine and some of the thumbnuts are too....the stainless ones. I think they went plastic.
We used to make a number of their machine frames and all the stainless grips....that was before they went with the china connection.
I don't want to get started.....but hey, they were a good customer for years. Our "bread and butter" so to speak.
