Metalworking tools are available for all members to use. While there is not a specific sign-off process on individual tools, members must be directly supervised by a staff or designated shop mentor while using any metalworking tools. Please discuss any project and metalworking tool use with a staff or designated shop mentor prior to using it. If you are in any way unsure about how to use a tool, please ask for demonstration and instruction. Staff or shop mentors may intervene if they see unsafe practices in the metal lab. You must use all appropriate PPE at all times when working in the metal lab. Auto-darkening welding hoods, fire retardant jackets in sizes M-XXL, welding gloves in sizes M-XL, Nitrile coated fabric gloves, and safety toe covers in sizes S-L are available to all members for use.
If you plan to use the CNC Plasma Table for the first time, you must ask a staff member or shop mentor to provide a demonstration on the startup and run procedures, and safety information for this machine. We can provide demonstration and instruction on any tools/processes on an on-going and as-needed basis. Questions and demonstrations are always encouraged to make sure you work safe in our space.
