This interesting woodworking project uses recycled materials to create simple picture frames. With basic shop tools and a little time, the possibilities are endless.
In regards to material, anything you can recycle works great. Old signs, material from discarded furniture, barn board and even palette wood will do nicely.
As an example, use a weathered piece of siding from a barn or old outbuilding. In order not to fabricate individual pieces to prepare the four sides, rip one long section to use as rough stock. Make certain all fasteners and debris are removed prior to cutting. If the width of your frame rails will be four inches, rip it accordingly. Once you have your stock, use a rabbeting bit on your router to create a channel that will accept the glass, picture and backing into the inside of the finished frame. Create this rabbet along the entire length of the ripped piece before cutting the four individual frame sides. This keeps things consistent.
Given the dimension of the picture you wish to display determine the inside dimension of the finished frame, taking into account the overall width of the rabbeted edges. You can now make the necessary miter cuts in your chop saw or miter box to create the four corners. With a jig or corner clamp, use wood glue to join the mitered pieces and allow the glue to set. With larger frames, you may choose to pre-drill and tack to the corners with brads. Set the nails and use wood filler if needed.
Your local hardware store will supply you with glass and hardware to hang your masterpiece.
