Homemade Band Saw Blade Sharpener

Homemade Band Saw Blade Sharpener WOODLOT EQUIPMENT 24-5-38 "Everyone who has a bandsaw sawmill needs one of these," says Harold Witulski, Beatrice, Neb., who recently sent FARM SHOW photos of a "band saw blade sharpener" that he designed and built. The blade sharpener uses a small grinder wheel that runs off a 12-volt motor. A windshield wiper motor, with a small crank attached to it, pushes the blade ahead and also brings a grinder down at the same time. The grinder mounts at one end of a steel arm, which has a counter weight at the opposite end to balance the grinder's weight. The grinder comes down to sharpen the front side of the teeth to a 10-degree slope. The grinder pivots on a bolt which can be adjusted to move the grinder forward or backward. A turnbuckle is used to adjust the up-and-down travel of the grinder. A small metal arm is used to push the blade ahead. A small ball bearing is positioned so that the arm rests on it and raises up when the grinder comes down. The entire setup mounts on a 15-in. long, 8-in. high piece of channel iron. The blade slides between the channel iron and a length of 2-in. wide strap iron. A pair of small wooden wheels are used to hold the blade down as it slides along on two 1/4-in. bolts, which can be adjusted to just let the blade slide easily. "I bought the grinder at a local hardware store and ground it down to fit the teeth on my saw," notes Witulski. Contact: FARM SHOW Followup, Harold W. Witulski, 8558 W.
