Abstract
A tension adjustment for a band saw having a band saw blade (30) encircling upper and lower band wheels (26, 28) disposed on opposite sides of the cutting table (12), with the lower band wheel (28) and the drive motor (66) being supported by a housing (50) which is pivotally mounted to the frame structure (10) of the band saw and which can be moved toward and away from the upper band wheel (26) by means of a threaded rod (84) extending between the frame (10) and the housing (50) so that the tension in the band saw blade can be adjusted by pivotal movement of the housing (50) supporting the lower band wheel (28).
