ABSTRACT:
Apparatus for retaining vanes in an abrasive blasting machine includes a rotatable runnerhead having a radially extending channel opening through one face of the runnerhead. A slot is included as part of the channel adjacent the radially outer end of the channel. A vane includes a base adapted to be disposed within the channel and retained there by a retaining pin fitted into the slot. A magnet is disposed in the slot in order to retain the pin in the slot at all times. The base includes a plurality of intersecting planar surfaces overlying the slot that cooperate to (1) enable the pin to be inserted and removed without displacing other machine components and (2) hold the pin securely in place during operation of the machine. The planar surfaces are configured such that the vane can be manufactured in a casting operation without using cores, thereby effecting significant cost savings.
