The creation of West Fork Tool, a subsidiary of West Fork Environmental, has increased our capacity to design and manufacture traditional pattern tooling and specialized PIT tag antennas. With the addition of 2 large CNC mills in our shop we have the ability to develop not only custom environmental monitoring equipment but also machined products. Marrying this business operations model with projects for water resources and forestry clients enables us to bring creative and traditionally expensive solutions to the marketplace efficiently and cost effectively. 

Our HAAS GR712 and HAAS VF34T place scheduling and control of specialized projects in our hands rather than outsourcing these critical tasks and furthers our capabilities in plastics design and fabrication. West Fork Tool also has full CAD/CAM technical capabilities, aluminum welding and instrumentation for customized fabrication solutions. 

West Fork’s CNC machines and shop allow for the precise design, machining and fabrication of custom PIT tag antenna systems, aluminum hogouts as well as wood, plastic and metal pattern tooling The seven foot by twelve foot travels have been essential in manufacturing large antenna arrays.  Extended “Z” travel option has proved very useful. Any part that is too big for these travels has been easily cut into interlocking pieces in Gibbscam software and thereafter machined in manageable sized parts for assembly on the workbench.

We are experienced in computer aided design and machining.
