A saw table for sheet material includes a platform having an abutment stop along one edge for engaging and locating sheet material supported on the platform. A mast is disposed adjacent to the platform edge for rotation about an axis perpendicular to the platform. A boom extends from the mast over the platform, and has an elongated track perpendicular to the axis of the mast. A carriage is carried by the boom for movement along the track. The carriage is adapted for mounting a saw, such as a circular saw, such that movement of the carriage along the track brings the saw into engagement with sheet material supported on the platform against the abutment stop.

What is claimed is: 1. A saw table for sheet material, which includes: a platform having an abutment stop for engaging and locating sheet material supported on said platform, a mast disposed adjacent to said abutment stop and rotatable about an axis perpendicular to said platform, a boom extending from said mast over said platform, said boom having an elongated track perpendicular to said axis, a carriage carried by said boom for movement along said track, said carriage being for mounting a saw such that movement of said carriage along said track brings the saw into engagement with sheet material on said platform against said abutment stop, a lock for locking said mast and said boom at a desired angular orientation with respect to said abutment stop on said platform, a support underlying said platform, a first disk secured to said support and a second disk secured to said mast in facing engagement with said first disk, said lock selectively permitting rotation of said mast and said second disk with respect to said support and said first disk, said first and second disks having peripheries with indicia for indicating angular orientation of said boom with respect to said abutment stop, said lock being a cam lock that includes a cam arm releasably engaging an underside of said support, a threaded shank extending from said cam arm through apertures in said disks, and a nut secured to said shank overlying said second disk. 2. The saw table set forth in claim 1 wherein said platform is rectangular, with said abutment stop extending along one edge of said rectangular platform and the opposing edge of said platform being free of obstruction such that the sheet material may be placed on said platform from a direction perpendicular to said abutment stop. 3. The saw table set forth in claim 2 wherein said abutment stop has a gap for permitting passage of the saw, and wherein said mast is disposed adjacent to said gap. 4. The saw table set forth in claim 1 wherein said first and second disks have openings for alignment with each other at selected angles of said mast and said boom, and wherein said lock includes a pin insertable through said openings. 5. The saw table set forth in claim 1 wherein said boom is of C-shaped cross section having opposed internal channels extending along said boom, and forming said track and wherein said carriage includes rollers for disposition in said channels for supporting said carriage on said boom. 6. The saw table set forth in claim 5 wherein said carriage is adjustable for selectively mounting saw shoes of differing configurations. 7. The saw table set forth in claim 1 wherein said platform is mounted on spaced rails that are adapted to be telescopically received over spaced rails on a sheet bending brake such that the sheet bending brake forms an extension of said platform. 8. A saw table for sheet material, which includes: a platform having an abutment stop along one edge for engaging and locating sheet material supported by said platform, an opposing edge of said platform being free of obstruction such that the sheet stock may be placed on said platform from a direction perpendicular to said abutment stop, a mast disposed adjacent to said one edge external to said abutment stop and rotatable about an axis perpendicular to said platform, indicia for indicating angular orientation of said mast about said axis, a lock for locking said mast at a desired angular orientation about said axis, a boom cantilevered from said mast over said platform, said boom having an elongated track perpendicular to said axis, a carriage carried by said boom for movement along said track, said carriage being for mounting a circular saw such that movement of said carriage along said track brings the saw into engagement with sheet material on said platform, and a support underlying said platform, a first disk secured to said support and a second disk secured to said mast in facing engagement with said first disk, said indicia being disposed on said first and second disks, said lock selectively permitting rotation of said mast and said second disk with respect to said support and said first disk, said lock being a cam lock that includes a cam arm releasably engaging an underside of said support, a threaded shank extending from said cam arm through apertures in said disks, and a nut secured to said threaded shank overlying said second disk. 9. The saw table set forth in claim 8 wherein said first and second disks have openings for alignment with each other at selected angles of said mast and said boom, and wherein said lock includes a pin insertable through said openings. 10. The saw table set forth in claim 8 wherein said boom is of C-shaped cross section having opposed internal channels extending along said boom, and forming said track and wherein said carriage includes rollers for disposition in said channels for supporting said carriage on said boom. 11. The saw table set forth in claim 10 wherein said carriage is adjustable for selectively mounting saw shoes of differing configurations. 12. The saw table set forth in claim 8 wherein said platform is mounted on spaced rails that are adapted to be telescopically received over spaced rails on a sheet bending brake such that the sheet bending brake forms an extension of said platform. 13. Apparatus for mounting to a platform to form a saw table, which includes: a mast for mounting adjacent to the platform for rotation about an axis perpendicular to the platform, a boom extending from said mast for positioning over the platform, said boom having an elongated track perpendicular to said axis, a carriage carried by said boom for movement along said track, and for mounting a saw such that movement of said carriage along said track brings the saw into engagement with sheet material on the platform, a lock for locking said mast and said boom at a desired angular orientation with respect to said axis, and a support for underlying the platform, a first disk secured to said support and a second disk secured to said mast for facing engagement with said first disk, said lock selectively permitting rotation of said mast and said second disk with respect to said support and said first disk, said first and second disks have peripheries with indicia for indicating angular orientation of said boom about said axis, said lock being a cam lock that includes a cam arm releasably engaging an underside of said support, a threaded shank extending from said cam arm through apertures in said disks, and a nut secured to said shank overlying said second disk. 14. The apparatus set forth in claim 13 wherein said first and second disks have openings for alignment with each other at selected angles of said mast and said boom, and wherein said lock includes a pin insertable through said openings. 15. The apparatus set forth in claim 13 wherein said boom is of C-shaped cross section having opposed internal channels extending along said boom, and forming said track and wherein said carriage includes rollers for disposition in said channels for supporting said carriage on said boom. 16. The apparatus set forth in claim 15 wherein said carriage is adjustable for selectively mounting saw shoes of differing configurations. 17. The apparatus set forth in claim 13 further including an abutment stop for mounting along one edge of the platform to engage and locate sheet material supported by the platform, said mast being adapted to be located adjacent to said abutment stop on the platform.
