The Broken Beaver; A Vermeer 1800A with a 110 HP John Deere, I Tech Motor W / Turbo, spinning a chipping drum a minimum of 2,000 RPM's and the shaft breaks and becomes three pieces!

This is part one to a series that fabricates a new rotating unit for the tree chipper, looking at what we have to replace and starting to whittle away on some steel for the center shaft!
