Abstract
A blasting wheel for projecting particulate against a surface employs a blade lock arrangement which eliminates the need for securing the blade between a pair of plates separated by a spacer. Rather the blades are secured at only one end thereof by use of an improved locking arrangement. The locking arrangement employs a back plate containing a blade alignment channel and a securing element. The back plate is secured to the drive shaft by means of a hub. A front plate sandwiches one end of the blade between it and the back plate. The front plate is adjacent the back plate rather than spaced therefrom.
