Do we have a 3/8-24 threading die? I looked through the cabinet but apparently didn’t find the right container.
Also - I found a 12mm tap sitting on the table next to the Cameron drill press. I couldn’t figure out where it belongs so it’s just sitting on the shelf in the cabinet.
Check the red tool box in the common area opposite automotive. There are dies of many sizes in the bottom. However, that one is UNF so you might have trouble finding one. Other suggestion would be old heavy wood boxes in the machine shop cabinets opposite the mills.
