What are the best joinery techniques for teak outdoor pet waste bins?

When constructing teak outdoor pet waste bins, selecting the right joinery techniques is crucial for durability and weather resistance. Teak wood, known for its natural oils and strength, requires methods that prevent moisture ingress and structural failure. The best joinery techniques include dovetail joints, which interlock tightly to resist pulling apart; mortise and tenon joints, offering robust connections for frame pieces; and finger joints, ideal for corners to maximize glue surface area. Use stainless steel or brass fasteners to avoid corrosion, and apply waterproof glue. These techniques ensure your bin withstands outdoor elements, maintaining integrity over time. Regular maintenance, like cleaning and oiling, further prolongs its life.
