How to Use a Glue Joint Router Bit


The glue joint router bit is a carbide-tipped cutter for use in a router table. The glue joint router bit creates a mechanical joint for wood pieces to be glued. This joint adds tremendous strength and ensures accurate alignment of the two pieces of wood. You can use the glue joint router bit for side-to-side board glue-up, as well as for door panels, table tops and cabinets. This router bit can cut wood up to 1 1/4-inch thick.

Step 1

Put on safety glasses and hearing protection.

Step 2

Use the table saw to cut several 3-inch-wide by 12-inch-long scraps of material, or test stock, the same thickness as your project's stock. These will be used to dial in the router bit and fence for a perfect fit.

Step 3

Install the glue joint router bit into router.

Step 4

Adjust the height of the bit so that the glue joint router bit is centered on the thickness of the wood to be milled.

Step 5

Adjust the fence so that it is even with the inside cutting surface of the glue joint router bit.

Step 6

Place a piece of scrap material against the router table fence. Adjust your feather boards to hold the stock firmly down and against the router table and fence.

Step 7

Start the router and run one piece of scrap test material through the router table. Have the best side of your wood face up for this cut.

Step 8

Start the router and run another piece of scrap test material through the router table. Have the best side of your wood face down for this cut.

Step 9

Lay both test pieces of scrap test material on a flat surface and check the fit. The two pieces should fit together with no gaps and be flush with each other.

Step 10

Repeat steps 7 through 9 until the pieces form a perfect joint. Adjust the fence or router bit height a little at a time until you produce a perfect joint. Save the test scrap material for templates to set the router and fence quickly and accurately for future bit setup.

Step 11

Now that you are ready to mill, just glue, clamp and sand for a perfect joint for your project.
