Always err on larger radius side. Use relief cuts, and drill relief holes where necessary. | Saw blade width | 1/8" | 3/16" | 1/4" | 3/8" | 1/2" | 5/8" | 3/4"| | Minimum sawing radius | 3/16" | 5/8" | 1" | 1 1/2" | 2 1/2" | 4"| 5 3/4"| ===== 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. **Premature blade breakage:** * Excessive feed pressure, and/or too much blade tension. * Worn or incorrectly set guides. * Joint improperly welded and annealed. * Blade too wide for curved cut. * Bandwheels worn. * Blade teeth of too fine pitch. **Blade bows in deep cut:** * Excessive feed pressure. * Blade teeth dull or of too fine pitch. * Insufficient blade tension, and/or blade too narrow for depth of cut. * Blade running off at start of cut. **Blade teeth dull rapidly:** * Insufficient feed pressure. * Blade pitch too fine. * Guide inserts snagging set of teeth. * Speed too fast. **Teeth tron from blade:** * Excessive feed pressure. * 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. **Blade vibrates in cut:** * Workpiece not properly seated or securely held. * Blade speed too fast, and/or blade pitch too coarse. * Insufficient blade tension. ===== Trainers & Maintainers ===== The following members are authorised to provide bandsaw training: * Cameron Sharp (cazagen) * Mike Walters (miek) If something is up with the bandsaw please contact one of the following people: * Cameron Sharp (cazagen) * Mike Walters (miek) ===== Log ===== //Started 09/06/2019 - maintenance prior to this may not be logged. // * **01/01/1970** Template log entry. Copy this below. //Author// * **09/06/2019** Found tool in an unusable state. Blade tracking was completely out, blade falling off back of wheels. Guide bearings were also mis-adjusted - blade was being forced into them and making a very angry noise when pulled through by hand. Spent 45 minutes re-adjusting the blade tracking to get the blade running true again, re-adjusted blade tension and guide bearings. //Alfie// * **07/12/2019** Found the blade blunt. Cameron replaced it with a new one. //Vytas// * **18/06/2022** Fitted a new blade as the old one was blunt. //Mike//
