Cutting apparatus and methods of operation

An apparatus, comprising:

• a frame having a hollow cylindrical receptacle;
• a material-routing tray mountable to the frame, the mounted tray moveable in a direction;
• a router-motor mounting structure having a cylindrical insert that is disposable within the hollow receptacle to allow swiveling of the router-motor mounting structure about an axis that is not parallel to the direction;
• and
• a router motor that is mountable to the router-motor mounting structure.

A material-cutting tray, comprising:

• a cutting side operable to hold a material to be cut, the cutting side having a length in a cutting direction and first and second ends perpendicular to the cutting direction;
• an underside;
• and
• a wheel assembly mounted to the underside and comprising four wheels each rotatable in the cutting direction and each positioned a respective nonzero distance from a closest one of the first and second ends.

A material-cutting tray, comprising:

• a cutting side operable to hold a material to be cut;
• an underside;
• and
• a wheel assembly mounted to the underside and comprising,
• tray-support wheels each rotatable in a cutting direction and operable to respectively engage first sides of guide rails, and
• a first retaining wheel operable to retain a first one of the tray-support wheels to a first one of the guide rails by engaging a second side of the first guide rail.

A cutting apparatus, comprising:

• a frame having a saw-mounting portion and a router-mounting portion that is separate from the saw-mounting portion, the saw-mounting portion having a hollow cylindrical saw receptacle and the router-mounting portion having a hollow cylindrical router receptacle;
• a saw mounting structure having a cylindrical saw insert that is disposable within the saw receptacle;
• a saw that is mountable to the saw mounting structure;
• a router mounting structure having a cylindrical router insert that is disposable within the router receptacle;
• a router that is mountable to the router mounting structure;
• and
• a material-cutting tray mounted to the frame and moveable in a cutting direction.

A material-cutting tray, comprising:

• a cutting side operable to hold a material to be cut;
• an underside;
• and
• a hand-operable retaining mechanism mounted to the underside and operable to secure the material-cutting tray to a guide rail and to allow removal of the tray from the guide rail.
