Radial arm saw mortising adapter

摘要

A simplified mortising adapter for converting a conventional radial arm saw, or other power tool having an arbor, into a mortising tool. The adapter includes a base plate and a drive spindle rotatably mounted to the base plate for connecting to the radial arm saw or other power tool's arbor and driving a chain saw adjustably attached to the base plate. The drive spindle has a socket having a characteristic shape which is generally complementary to the shape of the arbor so that those components can be drivingly engaged. The adapter also includes a clamp mechanism for clamping the base plate to the power tool in a manner such that the base plate can be adjusted to concentrically align the drive spindle with the arbor when the base plate is clamped to the power tool.
