ABSTRACT:
An air jet containing blade guide for stabilizing a band saw blade or a circular saw blade of a saw mill and guide blocks or inserts for a saw blade guide are disclosed. The inserts can be removably fastened to a blade guide by means of cap screws preferably containing a hex socket for tightening and loosening the screws with a hex wrench. Cap screw holes formed in the inserts contain recessed countersinks for recessing the heads of the cap screws below a blade opposing surface of the inserts when disposed in an operative position of a blade guide in a saw mill. The inserts can be constructed of brass or aluminum bronze which is softer than the blade being stabilized thereby to avoid undue blade damage but which are hard enough to provide good wearability and heat dissipation as against periodic blade impacts. The blade guide disclosed contains a threaded air inlet port and an air passageway extended between the port and a side of the guide facing a work piece when the guide is operatively positioned in the mill to permit high pressure air supplied to the input port to be directed toward the kerf of the work piece to clean the latter of saw dust.
