Abstract

A wood thickness attachment for a jointer planer that has an angle/wood guide and cutter roller is provided. The attachment is attached and adjusted to the angle/wood guide and includes a roller guide that will engage a piece of wood which can be cut by the cutter roller and modified wood thickness attachment, leveling and adjustment features are built into the roller guide to compensate for various height thicknesses of the piece of wood.

Claims

1. A wood thickness attachment for a jointer planar, said planar having an angle/wood guide and a rotary cutter wherein said attachment comprises:

(a) an L-shaped attachment bracket having a first horizontal leg mounted on the upper horizontal surface of said guide and a second vertical leg adjacent the vertical surface of said guide;

(b) an adjustment rod having a threaded shaft with a crank handle rotatably affixed transversely to said second leg of said bracket;

(c) a thickness adjustment plate threadably mounted on said shaft;

(d) a roller guide affixed transversely to said plate above said adjustment rod so that when a piece of wood is placed onto said jointer planer abutting said roller guide actuation of said crank handle will cause said roller guide to urge said piece of wood against said cutter.

2. A wood thickness attachment as recited in claim 1, wherein said roller guide includes:

(a) a pair of spaced arms transversely affixed to an upper portion of said thickness adjustment plate;

(b) said roller guide comprising a bar transversely affixed to and extending between said arms; and

(c) a plurality of balls rotatably mounted within the side of said bar to engage said piece of wood.

3. A wood thickness attachment as recited in claim 2, further comprising:

(a) a scale placed on said first leg of said L-shaped attachment bracket; and

(b) a pointer affixed to end of said bar adjacent said scale to determine the thickness to cut said piece of wood.

4. A wood thickness attachment as recited in claim 3, further comprising:

(a) said thickness adjustment plate having a pair of spaced vertical slots therein;

(b) a pair of adjustment bolts, each said bolts engaging with each slot and one of said arms of said roller guide so that said roller guide can be vertically adjusted;

(c) at least one leveling bolt having a foot, said leveling bolt being vertically threaded through said bar so that said foot engages with said first leg of said L-shaped attachment bracket to stabilize said roller guide to compensate for various height thickness of said piece of wood.
