+ | ===== Saw blade width and minimum sawing radius ===== | ||
+ | This is only a guide. Always err on larger radius side. Use relief cuts, and drill relief holes where necessary. | ||

+ | ===== Bandsawing practice ===== | ||
+ | //Copied from the manual.// | ||
+ | |||
+ | Maximum saw blade life : Medium saw blade tooth pitch, speed and feed. | ||
+ | |||
+ | Minimum sawing time : Coarse tooth pitch, fast speed and heavy feed. | ||
+ | |||
+ | Fine accurate finish : Fine tooth pitch, fast speed and light feed. | ||
+ | |||
+ | ===== Troubleshooting ===== | ||
+ | //Copied from the manual.// | ||
+ | |||
+ | |||
+ | **Blade wanders from true line:** | ||
+ | * Excessive feed pressure. | ||
+ | * Blade teeth dull or of too fine pitch. | ||
+ | * Guide inserts not controlling blade wear or incorrect adjustment. | ||
+ | * Blade tracking incorrect. | ||
+ | * Loss of set to one side of saw teeth. | ||
+ | |||

+ | * Gullets of teeth loading. | ||
+ | * Pitch of teeth too coarse. | ||
+ | * Blade speed too fast | ||
+ | |||
+ | **Blade developing twist:** | ||
+ | * Excessive feed pressure. | ||
+ | * Guide inserts snagging blade. | ||
+ | * Blade too wide for radius of cut. | ||
+ | * Excessive blade tension. | ||
+ | * Blade not tracking correctly. | ||
+ | * Loss of set to one side of saw teeth. | ||
+ | |||
