How to Make a Tongue Groove in Hardwood Flooring

Tongue and groove

Hardwood flooring is among the best flooring material for durability and long life. Installing it can be a bit difficult, especially when there is a need for modification of an existing plank. Knowing how to create a small piece of flooring out of a 1-by-2 inch piece of matching wood is also very helpful.

Things You'll Need

• Router
• Tongue and groove bit
• Clamps

Instructions

1. Secure the 1-by-2 inch lumber to a tabletop with clamps.

2. Set the bit in the router and tighten the shaft nut securely.

3. Set the height of the bit to cut the center out of the 1-by-2.

4. It may be necessary to make a couple of passes to create the groove needed.

5. Sand the groove to be certain there are no rough spots that may prevent the tongue for slipping into it.

Tips & Warnings

• Always wear safety glasses.

• Making more than one pass will help prevent splintering.

• Do not adjust router while it is running.
