1. Prepare a piece of stock 3/4" x 1-3/4" x 18".

2. Install miter gauge extension. Note: If you do not have a miter gauge extension, construct one using pieces of stock 3/4" x 2-1/2" x 18". Fasten to miter gauge with flat headed stove bolts. Counter sink or counter bore bolt holes.

3. Set saw blade to 5/8" height.

4. Make crosscut in scrap stock.

5. Place miter gauge in left table slot and make cross cut through extension.

Note: Let us decide that 3/8" will be the "kerf spacing".

6. 3/8" to the right of this cut, drive a 6 penny finishing nail 1/2" from bottom edge.

7. Cut off nail 1/2" from surface of extension. (See drawing)

11. Continue until kerfs are made the full length of stock.
