Abstract: A mounting assembly for demountable attachment to a tree. The assembly includes a mounting base, primary fasteners, and secondary fasteners. The mounting base includes a main body, first arm, and second arm. The mounting base is planar and rectangular. The main body includes a mounting hole medially located on the main body. The first and second arms extend from the main body opposite the mounting hole and thereby form a mounting slot. The first and second arms are positioned proximate and parallel to each other. The mounting slot is longitudinally positioned along the mounting base. The primary fasteners include first and second fasteners. First fasteners are demountably positioned in the mounting hole. Second fasteners are slidably and demountably positioned in the mounting slot. The mounting base is adapted to be attached to the tree via the primary fasteners. Secondary fasteners are adapted to affix fixtures to the main body.

Abstract: A tool for testing pressure/vacuum engine control switches includes a first and second housing. The housings each include inner and outer passages. The housings are attached with the inner passages placed adjacent each other. When attached, the housings form a continuous longitudinal passage. A pressure chamber is attached to the first housing and includes a valve. The valve provides a passage to a testing chamber. The testing chamber includes a receptacle, pressure/vacuum gauge, and a plug. The first housing also includes a vent and a piston/rod arrangement which define a fluid chamber in the first housing. The rod extends from the first housing through the inner passages and partially into the second housing. A seal is provided around the portion of the rod which passes through inner passages. A return spring is provided around the portion of the rod which extends into the second housing. A lock-and-swivel joint is located at the end of the portion of the rod extending into the second housing.
