Skip the Clamps and the Pocket
When making a pair of oval mirror frames recently, I was faced with (and dreading) the complex task of clamping up all those 221⁄2 ° miter cuts and keeping them snug in the process. After much thought, I turned to my pocket-hole jig for the solution.
After laying out the oval on the dry-assembled pieces and cutting biscuit slots in each joint, I drilled pocket holes in the waste area of the joints as shown at top. A dab of glue and a biscuit later, I simply screwed the joint together.
After the glue cured, I removed the screws and sawed out the frame. With this method, I got tight-fitting joints and because I glued only one joint at a time, didn't have to rush through the assembly before the glue set.
