How to Make Wood Trim & Molding


While wood trim can be as simple as nailing a piece of lumber in place and giving it a coat of paint, most wood trim and molding is processed using either routers or molding machines. These machines give the trim or molding a certain consistent look depending on the bits or blades used in the machine. Molding machines are available as standalone machines or may be an option on a wood planer for the home workshop.

Step 1

Choose the lumber you wish to use for wood trim or molding. The wood should be at least 5/8-inch thick and can be as wide as 6 inches depending on your needs.

Step 2

Set up your router and router table by assembling the router with the molding bit of your choice. If you are using a molding machine, load the molding knives and secure in place.

Step 3

Turn on the router or the molding machine.

Step 4

Begin feeding the lumber, one board at a time, either across the router bit or through the molding machine. If multiple passes are required, repeat the procedure.

Step 5

Continue until all the molding or trim needed for the project has been processed.

Step 6

Cut the finished molding or trim to the appropriate lengths for installation. Once installed, the trim is ready for finishing with paint or wood stain.
