Mark Biscuits for Better Frame Builds
When I make picture frames with mitered corners, I like to use the small, #FF biscuits to reinforce the joints. This size of biscuit works for frame stock at least 1-1/2" wide.
I came up with this simple triangular-block jig outfitted with cleats that fits over the dry-assembled joint. The jig marks the location of the biscuit to provide minimum clearance from the outside corner of the frame. Mark a line across the frame pieces along the triangle's edge to identify the location for the biscuit and registration point for the biscuit joiner.
