RAVEN Shaft turning at 5000 RPMs

There is nothing special about this shaft. It is just one of a pair being made for a client. It was selected just because it was close enough to being completed to test. The ferrule and tip are not even on it yet. There are several tests used to check the concentricity and balance of a RAVEN shaft while it is being made. One of the tests used to check a RAVEN shaft is to spin it a high speed. First a lathe pin is screwed into the threads of the shaft. The lathe pin is then clamped into the jaws of a chuck and centered. The shaft is not supported on the other end. It is allowed to hang free. It is then rotated at about 5000 RPMs. If you look closely at the chuck on the left hand side you can tell it is spinning. If the shaft is as close as wood can get to perfectly straight and perfectly balanced it will spin as if it was standing still like this shaft does. If the shaft isn't straight or it is unbalanced the centrifugal force will cause it to wobble wildly out of control and eventually the shaft will splinter. Don't try this at home boys and girls and definately do not try this with just any shaft.
