I was wondering what the torque at the blade of a metal cutting bandsaw
would be for a lighter duty machine. Or how powerful a motor do these
machines run, and what type of gear reduction do they use.

Thanks.


You have to look at the design of the saw.
The blade needs to run at a certain speed. This is a product of the wheel
diameter and it's speed. The speed of the wheel gives you your gear ratio.
The torque requirements are determined by the width of the blade (kerf), the
feed speed and the material being cut.
Generally, saws should be designed around the blade. The blade supplier
should be able to give you the minimum bend radius for the wheel as well as
the power requirements in various common materials. If in doubt, oversize
the motor and underspeed/underfeed the blade.
The minimum wheel size can be exceeded for a larger throat. Generally, the
larger the better for the saw wheels as the blade is flexed less.
