Abstract
Abstract The present invention is directed to a method and apparatus for shaping the inside corner of slabs of material comprised primarily of polymethyl methacrylate filled with alumina trihydrate. The process involves fastening a connecting slab between horizontal and vertical slabs and shaping the connecting slab with an arcuate shape which meets the flat surfaces of the horizontal and vertical slabs. The tool for the process has cutting surfaces to create the indicated inside corner shape and is used in conjunction with a base for a rotary motor router. The resulting product has a rounded inside corner which appears molded as a single piece, rather than a combination of pieces or slabs.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
78 words
A method for making a counter top comprising the steps of: fastening a connecting slab having parallel upper and lower sides between horizontal and vertical orthogonal slabs, said horizontal slab having a flat top surface and said vertical slab having a flat front surface; and sliding a rotating shaping tool across said connecting slab to arcuately shape said connecting slab to tangentially meet the flat top surface and the flat front surface of said horizontal and vertical slabs.
Claim 2
Independent Claim
78 words
A method for making a counter top comprising the steps of: fastening a connecting slab having parallel upper and lower sides between horizontal and vertical orthogonal slabs, said horizontal slab having a flat top surface and said vertical slab having a flat front surface; and sliding a rotating shaping tool across said connecting slab to arcuately shape said connecting slab to tangentially meet the flat top surface and the flat front surface of said horizontal and vertical slabs.
Claim 3
Dependent Claim
77 words
A counter top prepared by a process comprising the steps of: fastening a connecting slab having parallel upper and lower sides between horizontal and vertical orthogonal slabs, said horizontal slab having a flat top surface and said vertical slab having a flat front surface; and sliding a rotating shaping tool across said connecting slab to arcuately shape said connecting slab to meet the flat top surface and the flat front surface of said horizontal and vertical surfaces.
Claim 4
Dependent Claim
77 words
A counter top prepared by a process comprising the steps of: fastening a connecting slab having parallel upper and lower sides between horizontal and vertical orthogonal slabs, said horizontal slab having a flat top surface and said vertical slab having a flat front surface; and sliding a rotating shaping tool across said connecting slab to arcuately shape said connecting slab to meet the flat top surface and the flat front surface of said horizontal and vertical surfaces.
