Abstract
A rotating mechanism such as a model aircraft propeller shaft is balanced by a dynamic balancing apparatus comprising a disc rotating with the shaft and a stainless steel O-ring partly filled with mercury lodged in an undercut groove in the face of the disc. The method of manufacture involves placing the ring in the groove and compressing the ring to expand it radially into the undercut area.
