ABSTRACT:
An indexing system for use in a bandsaw sharpening machine which includes at least one grinding wheel for engaging the teeth of a bandsaw blade. An indexing block slideably disposed with respect to the bandsaw blade end has a pawl for engaging the blade to push it in a forward direction while friction pads inside the block frictionally engage the sides of the bandsaw blade. A wire link reciprocally moves the indexing block with a forward stroke pushing a tooth past an index finger. The index finger drops into the path of the tooth after the forward stroke and a reverse stroke is initiated pulling the block and blade back against the finger so as to hold the blade stationary as the wire link retracts the indexing block. The friction pads allow the block to slide along the blade to its initial position to ready it for the next forward stroke.
