A multi-purpose quick-change work surface platform for use with a power tool comprising:
- a substantially flat planar table platform having an opening through a work surface which opening has projecting from a peripheral edge a plurality of tabs, wherein each tab includes a raised end stop, wherein each tab protrudes into said opening on a plane parallel to but recessed below the work surface, and wherein adjacent tabs are separated by spaces;
- and
- a substantially flat planar tool base plate which attaches to a power tool and mounts within said table platform opening, wherein said tool base plate includes an opening for a tool member which protrudes from the power tool, wherein said tool base plate includes a plurality of circumferential recepticle slots recessed into a peripheral edge of said tool base plate, wherein a work surface of said tool base plate includes a plurality of cutout openings which communicate with said recepticle slots and are such that each of said tabs mounts within one of said cutout openings and is received into one of said recepticle slots upon inserting said tool base plate into the table platform opening and rotating the tool base plate, whereby said work surfaces are made coplanar and the power tool is secured to said table platform.
A multi-purpose quick-change work surface platform for use with a power tool comprising:
- a substantially flat planar table platform having an opening through a work surface which opening has projecting from a peripheral edge a plurality of tabs, wherein each said tab includes a raised end stop, wherein each said tab protrudes into said opening on a plane parallel to but recessed below said work surface, and wherein adjacent tabs are separated by spaces;
- and
- a substantially flat planar tool base plate which attaches to a power tool and mounts within said table platform opening, wherein said tool base plate includes an opening in which attachment means project from a peripheral edge into said opening for the engaging of a separate insert plate, wherein said tool base plate includes a plurality of circumferential recepticle slots recessed into a peripheral edge of said tool base plate, wherein a work surface of said tool base plate includes a plurality of cutout openings which communicate with said recepticle slots and are such that each of said tabs mounts within one of said cutout openings and is received into one of said recepticle slots upon inserting said tool base plate into said table platform opening and rotating said tool base plate, whereby said work surfaces are made coplanar and the power tool is secured to said table platform.
