Abstract
A router having a rotary bit is mounted on a table in a position to enable the bit to engage a workpiece on which is secured a template having a configuration corresponding to that to be duplicated on the workpiece. A template follower overlies and confronts the bit and has a socket in its lower end in which the tip of the bit may be accommodated to ensure that the bit and the follower are coaxial. The socket is defined by a side wall which is adapted to engage the edge of the template and thereby prevent engagement between the bit and the template.
Claims14
In routing apparatus for use in cutting a workpiece to the shape of a template secured to said workpiece and including workpiece support means having a generally horizontal upper surface and an opening through said table, a rotary router bit extending through said opening and having a free end at a level above that of said table surface, and means for rotating said bit about an axis, the improvement comprising:
- a guide pin overlying said table and extending toward the upper surface thereof,
- said guide pin having a socket at its lower end for accommodating the free end of said bit;
- and adjusting means for locating said bit and said socket relative to one another so that said socket accommodates said free end of said bit and ensures a coaxial relationship between said bit and said guide pin.
Apparatus for use with a router having a bit rotatable about an axis and extending vertically above the surface of a workpiece support, said apparatus comprising:
- a supporting arm overlying said workpiece support;
- a guide pin carried by and depending from said arm, said guide pin terminating at its lower end in a socket;
- and
- means for adjusting said guide pin laterally and axially of said bit,
- said guide pin terminating at its lower end in a socket of such size as to accommodate a portion of said bit and enable said guide pin and said bit to be coaxial, said socket being defined by a side wall that is engageable with said template to prevent engagement of said bit with said template.
Apparatus for routing a workpiece to conform to the configuration of a template that is secured atop said workpiece, said apparatus comprising a router having a bit rotatable about an axis;
- means for mounting a router in a position to enable said bit to engage said workpiece;
- a template follower;
- means supporting said follower in a position overlying and confronting said bit and for movements toward and away from said bit, said follower having a socket therein of such size as to accommodate a portion of said bit;
- and means mounting said follower for movements laterally of said axis to a position in which said socket and said bit are coaxial, said socket being defined by a side wall of said follower which is engageable with said template to prevent engagement of said bit with said template.
