If you intend to make an 8″ hole, choose plywood with a size ranging from twenty inches to 30 inches. If you already have the plywood piece, you can set them on your steel or wooden table by clamping them on the table. 

Ensure that the table is more extensive than your plywood. Then, set the drill by turning it upside down while you clamp it firmly with the plywood.

Make some adjustments if needed.

The center of the dowel must be parallel to the drill. You can utilize tiny shims for adjusting the position of the board.

Step 4: You Can Start Drilling

Stick with one diameter bit throughout the entire process. Using the 1/8″ bit, you can start drilling a 3″ long hole that remains straight. Then, you can transition to the use of a 6″ drill bit. 

You should refrain from drilling out of track. Once you are about to reach the end of the 6″ drill bit, transition to using a 12″ drill bit. You should check the level once again. Ensure that you’re drilling parallel with the stock. Besides, during the drilling process, stop every once in a while to clear sawdust away.
