Abstract: A vane for insertion into a slot of a wheel of a blasting assembly such that the vane propels media as the wheel is rotated includes a body radially extending between a first vane end and a second vane end, between a first flange and a second flange, and having opposing vane side surfaces. An attachment portion integral with the second flange, the attachment portion configured to be received into the slot, and the attachment portion having a first vane end retaining surface and a second vane end retaining surface that are configured to abut the wheel. The first vane end retaining surface and the second vane end retaining surface are adjacent to each other, the first vane end retaining surface is convex, and the second vane end retaining surface is concave.
