Grain and Color are Important
This technique requires 1-1/2-in. square stock. For a frame to look good, the grain must flow smoothly around all four pieces (see “Oops,” below) and the color must be consistent. Choose clear, straight-grained wood for your frame stock. It’s best if you can cut the frame stock from a single length of wood. Buy extra wood for test cuts. We found 1-1/2-in. square oak stair balusters sold at home centers to be an excellent source for frame stock.
Set Up for the Cuts
1. Rough-cut the frame stock to a few inches over the finished dimensions for cutting on the tablesaw.
2. Sketch the cuts on the end of each piece for orientation (Photo 1; Fig. A). All cuts start at the same end, so if you find yourself reversing the piece, something is wrong. Pay attention to grain direction! (See Fig. A and “Oops.”)
3. Cut spacer strips 3/8, 5/8 and 3/4 in. wide by 18 in. long. You’ll use these for setting the fence and saw blade height for some of the cuts.
Making the Saw Cuts
4. Set the blade to make a 3/8-in.-deep cut and make Cut 1 (Fig. A, below).
5. Set the blade and fence for Cut 2 (Photo 2) and make the cut.
6. Make Cut 3 with the blade titled to 33 degrees. Set the blade just high enough to poke through the wood about 1/4 in. (Photo 3).
7. Make Cut 4 to create the rabbet that holds your picture, matte and glass (Photo 4). Set the fence and blade height using Cut 1 as a reference.
Sanding, Mitering and Gluing
8. Sand the frame before cutting the miters (Photo 5). It’s a lot easier than sanding into the corners of an assembled frame.
9. Before you cut the miters, take a 1/2-in.-thick slice off your stock. Save the slice for setting up the last cut.
10. Attach a long subfence to the miter gauge. Use a drafting square to set the gauge at 45 degrees. (see “Tips for Perfect Miters,” AW #108, July 2004).
11. Cut the miters (Photos 6 and 7). (If you make a lot of picture frames, you may want to build our simple miter sled found in AW #96, October 2002, page 84.)
12. Test-fit the frame with a band clamp before gluing to check for tight-fitting joints.
13. Glue the frame together, spreading a heavy coat of glue over the entire miter (Photo 8). Yes, that includes the part that will eventually be cut off. Wipe off excess glue with a damp rag.
The Final Cut (The Fun Part!)
14. Set up the tablesaw for Cut 5 (Photo 9).
15. Make the final cut on all four sides of the frame (Photo 10).
16. Lift the frame from its four-sided offcut (Photo 11). (You may want an audience for this step).
17. If the inner frame doesn’t fall away from the offcut immediately, don’t panic. Ours didn’t (and of course, we panicked). It turned out that despite our best efforts, the blade was set a hair too shallow. All we had to do was push down gently on the frame to break that sliver of wood and release the offcut.
Finishing Touches
18. Reinforce the corners with 1-in. wire brads (Photo 12). Predrill the holes with a No. 60 wire gauge bit or clip the head off a brad and use that as a bit. You may need to use a mini-chuck if your drill doesn’t hold a bit that small (see Q&A, AW #107, May 2004). We don’t recommend using a nail gun for this step—it’s too easy to blow a nail out of the face of the frame. The nail would be hard to extract, and the resulting damage, difficult to repair. With a drill, if you accidentally drill a hole in the wrong spot, it’s easy to hide with filler.
19. Sand the outside of the frame and fill the nail holes. Stain as desired and finish with at least two coats of varnish or polyurethane.
