Free tutorial to build a craftsman style frame.
1 - 1x3 8 feet long
1 - 1x2 3 feet long
Please read through the entire plan and all comments before beginning this project. It is also advisable to review the Getting Started Section. Take all necessary precautions to build safely and smartly. Work on a clean level surface, free of imperfections or debris. Always use straight boards. Check for square after each step. Always predrill holes before attaching with screws. Use glue with finish nails for a stronger hold. Wipe excess glue off bare wood for stained projects, as dried glue will not take stain. Be safe, have fun, and ask for help if you need it. Good luck!
For a frame with inside measurement 8x12:
2 - 1x3 @ 12" (sides)
1 - 1x2 @ 13" (top)
1 - 1x3 @ 13" (top)
1 - 1x2 @ 14" (bottom)
1 - 1x3 @ 14" (bottom)
Attach the 1x2 to it's corresponding 1x3. The easiest way is 3/4" pocket holes and 1 1/4" pocket hole screws and glue.
Now drill 2 3/4" pocket holes on each end of the sides and attach to top and bottom. Sometimes your wood will split when attaching this way. You can prevent by drilling slowly, and unscrewing and rescrewing screw as you go to soften up wood. Another trick is to take a small drill bit and predrill a hole into second board through first pocket hole with joint clamped. And if all else fails, this is a frame, no structure really here - so try setting jig to 1/2" setting and using 1" pocket hole screws.
Frame can be hung with a sawtooth hanger or other hanging hardware.
