Cutting miter joints can be an involved process that can take hours and practice to perfect. With a simple set up on a table saw, you can cut all of your joints quickly, efficiently, and accurately without having to worry about measuring cuts with the rip fence. After making all of your cuts, a quick assembly can be accomplished using a few tools. For this example we're going to make a simple cube.
Tools and Materials Required:
Six pieces of wood cut to the exterior dimensions of your cube
Scrap M.D.F. cut the length of your rip fence
Blue painters tape
Step 1: Setting Up the Fence
For a left tilt table saw, the fence needs to be placed to the left of the blade (do the exact opposite for a right tilt table saw). Attach the M.D.F. to the side of the fence facing the blade using the bar clamps. It is important that the clamps be positioned far enough apart so that they will not hit the blade, and high enough so that they will not interfere with your material.
Place one of your pieces of wood against the M.D.F. and draw a line at the top of your material.
Step 2: Setting Up the Saw
For making these miter cuts, you will need to remove any blade guard, splitter, or riving knife from the saw. Tilt the blade to 45 degrees (or desired angle). Move the fence close to the blade and adjust the height so that the top of the teeth are in line with the mark on the M.D.F.
Turn the saw on, and push the fence into the blade until the top tooth is fully inside the sacrificial fence. Adjustment may be required, so feel free to turn the saw off and check for proper alignment.
Setting the saw in this position will allow you to remove the perfect amount of material from your wood to produce a miter cut. It will also greatly reduce any tear out on plywood or other veneered lumber.
