1. Dado And Rabbet Joint

Description:
A dado and rebbet joint is usually made with two pieces of equal thickness and width. A tongue in the end of one piece, formed by a rabbet having depth and width equal to one half stock thickness, exactly fits into a dado cut in the second piece. The outside edge of the dado is one half stock thickness from the end of the stock.

Use:
Dado and rabbet joints are extensively used in cabinetmaking. When cut for a snug fit and adequately glued, the joint is strong. Use for drawer and box corners is common.

Operations:
Warning: When cutting dadoes and rabbets, it is necessary to remove the upper guard. Whenever you remove the upper saw guard, keep the lower guard in place and work with extreme caution.

1. Prepare a piece of stock 3/4" x 3" x 10".

2. Crosscut stock into two pieces of equal length.

3. Mark pieces "A" and "B". Note: Since standard 1" stock does not always measure exactly 3/4", cutting the dado and rabbet to 3/8" measurements will not necessarily be 1/2 the stock thickness. However, it will make a completely satisfactory joint.

4. Butt the end of "B" across end of "A" to form a right angle and square a line on edge of "A" indicating exact width of stock.

5. Mark a second line on edge of "A" exactly 3/8" away.

6. Set saw blade height at 3/8" and lock carriage with blade close to left edge of table slot.

7. Set fence so the outer saw blade tooth is on line farthest from fence.
