Hand-held band saw

Abstract

A powered hand-held band for cutting a work piece and a method for manufacture and use. The band saw includes alternate blade guides respectively for selectively using one of a first cutting path for cutting a work piece flush with respect to a work surface and a second cutting path for non-flush cuts.

1 . A powered hand-held band saw for use in cutting a work piece angularly extending from a substantially planar work surface, the saw having a closed-loop saw blade circulatable about a blade travel path, the saw comprising:
 a frame housing the saw blade and at least partially defining the blade travel path and a cutting guide surface;   a motor connected to the frame and engaged with the saw blade to circulate the saw blade along the blade travel path; and   at least one first blade guide connected to the frame for guiding the saw blade along a first cutting path portion of the blade travel path, the first cutting path providing for a substantially flush cut of the work piece with respect to the work surface.   
     
     
         2 . The band saw of  claim 1 , wherein the first cutting path is substantially planar to the frame cutting guide surface. 
     
     
         3 . The band saw of  claim 1 , wherein the first blade guide comprises a pair of blade guides separated from each other along the first cutting path. 
     
     
         4 . The band saw of  claim 3 , wherein the frame defines a channel positioned between the respective first blade guides along the first cutting path. 
     
     
         5 . The band saw of  claim 1 , further comprising at least one second blade guide connected to the frame for guiding the saw blade along a second cutting path portion of the blade travel path, the second cutting path positioned inward of the frame cutting guide surface with respect to the first cutting path providing for a non-flush cut of the work piece with respect to the work surface. 
     
     
         6 . The band saw of  claim 5 , wherein the second blade guide comprises a pair of blade guides separated from each other along the second cutting path, the second blade guides positioned so that the second cutting path is angularly displaced with respect to the first cutting path. 
     
     
         7 . The band saw of  claim 5  wherein the saw blade is selectively positionable along one of the first and the second cutting blade paths for selective flush or non-flush cutting of the work piece with respect to the work surface. 
     
     
         8 . A powered hand-held band saw for use in cutting a work piece angularly extending from a substantially planar work surface, the saw having a closed-loop saw blade circulatable about a blade travel path, the saw comprising:
 a frame defining a substantially planar cutting guide surface;   a drive motor connected to the frame;   a drive pulley rotatably connected to the motor and engaged with the saw blade, the drive pulley partially defining the blade travel path;   at least one first blade guide connected to the frame and positioned along the blade travel path adjacent the cutting guide surface, the first blade guide defining a first blade cutting path portion of the blade travel path, wherein the first cutting path providing for a substantially flush cut of the work piece with respect to the work surface.   
     
     
         9 . The band saw of  claim 8 , wherein the first cutting path is substantially planar to the frame cutting guide surface. 
     
     
         10 . The band saw of  claim 8 , wherein the first blade guide comprises a pair of blade guides separated from each other along the first cutting path. 
     
     
         11 . The band saw of  claim 10 , wherein each of the pair of blade guides includes a single, continuous blade guiding surface. 
     
     
         12 . The band saw of  claim 8  further comprising at least one second blade guide connected to the frame for guiding the saw blade along a second cutting path positioned along the blade travel path, the second cutting path positioned inward in the frame with respect to the first cutting path providing for a non-flush cut of the work piece with respect to the work surface. 
     
     
         13 . The band saw of  claim 12 , wherein the second blade guide comprises a pair of blade guides separated from each other along the second cutting path, the second blade guides positioned so that the second cutting path is angularly displaced with respect to the first cutting path. 
     
     
         14 . The band saw of  claim 12 , wherein the second cutting path is inward of the first cutting path relative to the cutting guide surface. 
     
     
         15 . The band saw of  claim 12 , wherein the saw blade is selectively positionable along one of the first and the second cutting blade paths for selective flush or non-flush cutting of the work piece with respect to the work surface. 
     
     
         16 . The band saw of  claim 15 , further comprising an idler pulley connected to the frame and engaged with the saw blade; and wherein the blade travel path is defined by the drive pulley, the idler pulley, and one of the first blade guide and the second blade guide. 
     
     
         17 . The band saw of  claim 16 , wherein the frame defines a channel extending inward between the drive pulley and the idler pulley from a side of the frame including the cutting guide surface; and wherein the first blade cutting path spans the channel.
