?Estimate bandsaw surface speed, tooth bite and gullet fill.
Feed Speed mode calculates the maximum feed speed, limited by available power, gullet capacity and the max. feed speed. Power mode calculates the power required at a given feed speed.
Saw Data sets the wheel and blade geometry. Cutting Data sets the cut, species and power or feed speed.Bandsaw Calculator
Gray boxes are editable cells; all others are calculated.

?Selecting a species sets its specific gravity. Entering a specific gravity manually sets the species to "Other".Species
?SG = Specific Gravity of the wood species.Specific gravity
?1.8–2.0 for slow growing species (e.g. Northern Spruce); 2.5 for fast growing species (e.g. Southern Yellow Pine).Sawdust expansion factor
?Gullet area factor is 0.42 for square back tooth, 0.52 for round back.Gullet area factor
