A router guide template (30", 30′′′) comprising: • a base portion (33", 33′′′); • a top portion (31", 31′′′); • an exterior surface (32a", 32a′′′) interconnecting said base portion (33", 33′′′) and said top portion (31", 31′′′) along an outer periphery of the template (30", 30′′′) and an interior surface interconnecting said base portion (33", 33′′′) and said top portion (31", 31′′′) along an inner periphery of the template (30", 30′′′), wherein said exterior surface (32a", 32a′′′) is continuously tapered between said base portion (33", 33′′′) and said top portion (31", 31′′′) adapted to enable adjusting the depth of the guide on the taper on the template (30", 30′′′) for adjustments to the size of cuts and carves to facilitate joinery cuts and carves with a single template, wherein said base portion (33", 33′′′) is adapted for removable and adjustable interconnection with a template holder and wherein said interior surface further comprises a plurality of stepped interior surfaces (32b", 32c, 32b′′′, 32c'), an upper interior surface (32b", 32b′′′) generally describing in cross section a stadium shape having first and second ends and an elongated middle portion and a lower interior surface (32c, 32c') generally describing in cross section a stadium shape having first and second ends and an elongated middle portion, wherein at least the ends of said lower interior surface (32c, 32c') comprise a smaller circumference surface than at least the ends of said upper interior surface (32b", 32b′′′) such that an intermediate step is formed at least adjacent the ends of and between the upper interior surface (32b", 32b′′′) and the lower interior surface (32c, 32c'). • a base portion (33", 33′′′); • a top portion (31", 31′′′); • an exterior surface (32a", 32a′′′) interconnecting said base portion (33", 33′′′) and said top portion (31", 31′′′) along an outer periphery of the template (30", 30′′′) and an interior surface interconnecting said base portion (33", 33′′′) and said top portion (31", 31′′′) along an inner periphery of the template (30", 30′′′), wherein said exterior surface (32a", 32a′′′) is continuously tapered between said base portion (33", 33′′′) and said top portion (31", 31′′′) adapted to enable adjusting the depth of the guide on the taper on the template (30", 30′′′) for adjustments to the size of cuts and carves to facilitate joinery cuts and carves with a single template, wherein said base portion (33", 33′′′) is adapted for removable and adjustable interconnection with a template holder and wherein said interior surface further comprises a plurality of stepped interior surfaces (32b", 32c, 32b′′′, 32c'), an upper interior surface (32b", 32b′′′) generally describing in cross section a stadium shape having first and second ends and an elongated middle portion and a lower interior surface (32c, 32c') generally describing in cross section a stadium shape having first and second ends and an elongated middle portion, wherein at least the ends of said lower interior surface (32c, 32c') comprise a smaller circumference surface than at least the ends of said upper interior surface (32b", 32b′′′) such that an intermediate step is formed at least adjacent the ends of and between the upper interior surface (32b", 32b′′′) and the lower interior surface (32c, 32c').
