Abstract

A method for deep drilling into a panel composed of compressed polyester fibers includes providing a guide system, aligning the guide system with the panel, applying a force to a face of the panel, and drilling a hole into the edge of the panel with the guide system and the drill while the force is applied to the face of the panel. The guide system supports a drill having a drill bit for movement in an axial direction. The force is applied to an area of the panel that is in axial alignment with the guide system.

First claim

What is claimed:

1. A method for deep drilling into a panel composed of compressed polyester fibers, the panel having an edge and a face, the method comprising:
providing a guide system, the guide system supporting a drill having a drill bit for movement in an axial direction;
aligning the guide system with the panel;
placing a weight on the face of the panel, the weight being placed on an area of the panel that is in axial alignment with the guide system and spaced apart from the edge of the panel; and
drilling a hole into the edge of the panel with the guide system and the drill while the force is applied to the face of the panel,
wherein the edge of the panel is a first edge, wherein the panel has a second edge opposite the first edge and a length measured between the first edge and the second edge, and wherein placing the weight includes positioning the weight to extend a majority of the length of the panel in axial alignment with the guide system.

2. The method of claim 1 , wherein the drill bit includes a hollow body having a smooth outer surface and a sharpened edge without cutting teeth, and wherein drilling the hole includes receiving part of the panel in the generally hollow body.

3. The method of claim 1 , wherein drilling the hole includes inserting the drill bit into the edge of the panel at a rate of approximately 1 inch per second.

4. The method of claim 1 , wherein drilling the hole includes rotating the drill bit with the drill at a rate of 800 to 1100 rpms.

5. The method of claim 1 , wherein drilling the hole into the edge of the panel includes drilling a hole having a length of at least 6 inches.

6. The method of claim 5 , wherein the length of the hole is at least 10 times a diameter of the hole.

7. The method of claim 5 , wherein the edge of the panel is a first edge, wherein the panel has a second edge opposite the first edge and a length measured between the first edge and the second edge, and wherein the length of the hole is at least half the length of the panel.

8. The method of claim 1 , wherein the panel has a thickness between 0.5 inches and 1 inch.

9. The method of claim 1 , wherein providing the guide system includes
providing a support rail,
positioning a guide block adjacent the edge of the panel, the guide block receiving at least a portion of the drill bit to guide movement of the drill bit relative to the panel, and
coupling a slider to the support rail, the slider supporting the drill.

10. The method of claim 1 , wherein drilling the hole includes moving the slider along the support rail in the axial direction toward the panel.

11. The method of claim 1 , wherein the weight is at least 20 pounds.
