The LJ Bevel Box is a right angle gearbox using steel bevel gears, designed to integrate with a CIM Motor (am-0255), CIM-Sim (am-0932), 57 Sport, NEO, or CIM Sport. This setup allows for the use of a gearbox or CIM motor in locations where you may not have the space available for an assembly in a straight line. We recommend using this gearbox in low torque setups. An E4T encoder can be added to the side of this gearbox, but is not included.

LJ: Larry Jones

This product is named after Larry Jones, the uncle of AndyMark president Andy Baker. He passed away during the fall of 2013. He was the main inspiration to Andy in becoming an engineer, and is one of Andy’s heroes. Larry grew up in Indiana and was a graduate of Purdue University and worked on many projects during his lifetime, including designing lawn tractors and military training devices. He enjoyed his profession, working as an engineering manager at Wheelhorse, Jet Propulsion Laboratory and Caltech. For the past two decades, Larry worked on the LIGO project as a mechanical engineer. This project includes very large installations of lasers, mirrors and detection equipment which culminate in the goal of detecting gravity waves.

Larry was gifted in not only being a technically sound engineer, but also was a master communicator. He could easily explain the most complex systems and theories so that a child could understand what he was explaining. He would tell stories in a way which would capture the attention of his grandchildren, nieces and nephews, all while displaying his charismatic smile.

Most importantly, Larry was a devoted and faithful husband, father, and leader. His community involvement, church leadership, and care for his family was inspirational to all who had the pleasure to know Larry. Naming this gearbox after Larry is a small token to pay tribute to a great man. Rest in peace, Uncle Larry.
