The “Dino” model PF 12v grinder is a versatile bandsaw blade sharpener capable of sharpening blades from 19 to 90mm (3/4″ to 3.5″) in width with tooth pitches from 8 to 38mm (5/16″ to 1 1/2″). It should be used in conjunction with the “Dino” Automatic Setting Machine to maintain your blades at optimum efficiency.
Bandsaw blades suffer large stresses because they are continually flexing as they travel around the band wheels. This flexing, as well as the teeth being pulled back, causes them to develop minute cracks, especially in the gullet bottoms. Keeping them sharpened and gummed out is critical, not just to keep the cutting edge keen, but equally, to remove these cracks before they develop into serious problems.
The object of sharpening them is to remove the minimum amount of material over the whole tooth profile, while refreshing the cutting faces and maintaining a good tooth shape. A bad shape can lead to premature gullet cracking and inefficient cutting. Try to maintain smooth contours throughout the tooth profile to minimise stress raisers. Most, but not all, commercially available bandsaw blades have a “good” tooth shape.
Read these instructions thoroughly before using the grinder. Make all major adjustments with the motor switched off. When initially setting up do not run the grinder motor. This will minimise errors and unintentional damage to blades. ALWAYS WEAR SAFETY VISOR AND DUST MASK WHEN USING THIS GRINDER!
