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.
An improved angle guide for a band saw blade guid assembly of a saw mill which conventionally includes a base plate for attachment of saw stabilizing metal insert thereto and a backing plate adjoining one end of said base plate and extending at a right angle from said base plate for attachment to the saw mill, the improvement of which comprises a block member disposed in a corner between said plates extending along said corner parallel to, opposing and spaced from a back edge of a band saw blad of the mill when said angle guide is disposed in an operative position, said block member defining an anir inlet port opening onto a surface thereof for attachment to a source of high pressure air, said block member also defining a hollow passageway extending from communication with said inlet port to an opening on a side of said block member expelling high pressure air along the back edge of the band saw blade in a direction of a work piece to be cut by the band saw blade when said angle guide is operatively positioned in the mill.
