Making picture frames out of old fence boards is a much better use for them than throwing them away. Since fence boards are naturally weathered, they make an excellent material for creating rustic home furnishings and other small woodworking projects.
The goal of this project is to build a rustic cedar picture frame around a 12" x 18" enlarged photo. The finished picture is shown above.
The only materials required are:
The tools that I used to build my frame are as follows:
Pick out a couple of straight used fence boards. When making picture frames from fence boards, the used ones are the best. They have much more character than the new ones, and using them for another purpose after they have served their usefulness on the fence, provides continued value.
Using your table saw, rip both of the fence boards at around 2 inches. Both pieces of the rip will be used to build the frame. You should end up with one piece about 2 inches wide (the inside part of the frame) and the other piece about 1.5 inches wide (the outer part of the frame).
Insert a .25" rabbet bit in your router, and adjust the depth to .25". I use this size rabbet cut when making picture frames because the thickness of a 1/8" thick piece of glass and picture (which hardly has any thickness), and cardboard backing, when inserted into the frame, is almost flush with the back of the frame. You'll see this come together in some later steps.
Make a rabbet cut along the entire length of both 2" wide rips (see image below).
The rabbeted board will form the inside part of the frame. The glass, picture and carboard backing will fit into the grove.
One of the most important steps in making picture frames is to cut the frame the exact size that you want it. The key is to measure the frame parts from the points indicated below. First, determine the exact dimensions of the glass - you can cut the picture and the cardboard backing if needed, but the glass would be more difficult.
Assuming that the glass is exactly 12" x 18", measure and mark your frame parts 12 1/8" and 18 1/8". Using a miter saw, cut a 45 degree angle on each end of each piece (see diagrams).
Once you have the pieces cut, assemble them on a flat surface and, before permanently attaching them together, lay the piece of glass in the rabbeted cut to make sure your frame is the correct size. If it is a little bit larger - that is good, but you don't want it to be too large. If the glass, when slid off to one edge leaves a gap on the other side of the frame, the frame is too large. Cut a little off of the frame parts as needed to give a nice fit, but not snug. You don't want to force the glass in the frame. It will break... trust me... :-/
Once the frame pieces are the size that you want them, attach them using a finish nailer, such as the one shown below.
Next, using your miter saw again, cut the outer part of the frame (the 1.5" part). It should wrap around the inner part as shown below. Attach with the finish nailer.
Once completed, the frame should appear as shown below. If both sides are the same length and the top and bottom are the same lenth, the frame corners should be square and the 45 degree joints should be tight.
Next, cut a piece of cardboard to use as backing for the picture. The purpose of the backing is to hold the photograph tight against the glass, so that there are no ripples in the picture.
Next, insert the cleaned glass, picture, and backing into the frame. Secure the backing with another layer paper backing (not shown) and staple in place around the edges. Install picturing hanging hardware as desired. As you can see, making picture frames is easy! :-)
