A splitable modular doghouse includes: a first doghouse body, a second doghouse body, and locking assemblies. A side of the first doghouse body and a side of the second doghouse body can be operatively and detachably connected through the locking assemblies. The doghouse bodies of the splitable modular doghouse are detachably connected through the locking assemblies, so as to adapt to a body size of a dog. Therefore, it is convenient to replace a damaged doghouse body and thus the cost can be reduced consequently.

An infinity jig, infinity plug and a method of forming an infinity joint is presented. The infinity jig has a base with a work surface and an upright with a work surface connected to the base at an approximate perpendicular alignment. The upright includes a plurality of drill guides that are positioned such that a portion of a drill bit inserted into the drill guide extends below the work surface of the base. An infinity hole is formed by using a drill bit having a stop collar to drill partially into a workpiece with a portion of the drill bit exiting a connecting surface of the work piece. To form an infinity joint, two workpieces having infinity holes therein are aligned with one another and an infinity plug is inserted in the aligned infinity holes. The infinity plug pulls the two workpieces together providing a tight and aesthetically pleasing joint.
