This video demonstrates a detailed woodworking process for creating a custom picture frame from butternut hardwood. The creator showcases an efficient method for milling a decorative profile using a large router bit in a single pass. Key techniques highlighted include pre-varnishing the profiled stock before assembly to ensure a clean finish in complex corners, and a unique method for assembling the mitered joints using hot glue, which involves pre-heating the wood with a heat gun for a stronger, faster bond. To ensure long-term durability, the assembled frame's corners are reinforced with splines cut using a simple table saw jig. The video concludes with final finishing steps, including trimming the splines, applying a final coat of varnish, and adding hardware like a keyhole slot for hanging and felt pads to protect the wall.
Building a Wooden Picture Frame: Techniques and Tips
0:00 Efficient Profiling: Instead of using a table saw, which is time-consuming, a large profile router bit is used to cut the decorative shape of the frame in a single, consistent pass.
2:14 Pre-Varnishing for a Better Finish: A rabbet is cut for the glass and backing. To avoid difficulty in finishing tight corners after assembly, the intricate profile is pre-varnished.
2:46 Unique Hot Glue Assembly: A special technique is used to assemble the mitered corners. The wood is pre-heated with a heat gun, hot glue is applied, and the glue itself is heated until it bubbles. This ensures the glue flows well and creates a quick, strong initial bond.
3:51 Reinforcing Corners with Splines: Recognizing that hot glue is not a permanent solution for joints, the corners are reinforced with wooden splines for superior strength and longevity.
4:05 Simple Spline-Cutting Jig: A dedicated sled is not required to cut the spline slots. The video demonstrates a simple and effective jig setup on a standard table saw to cut the corner slots accurately.
4:58 Final Finishing and Sanding: After the glue sets, the protruding splines are trimmed flush on a bandsaw and then sanded smooth on a belt sander before the entire frame receives its final coat of varnish.
5:46 Adding Hanging Hardware: A keyhole slot is drilled into the back of the frame to allow it to be hung flush against a wall.
6:32 Wall Protection: Small felt pads are attached to the back corners of the frame to prevent it from scratching the wall surface.
