      • Testing Ratchet Wrenches

      • Wrench qualifications
        • Ratcheting Wrench
        • Non-Reversible
        • Zero-degree offset
        • ½” hex
        • 12 or 6 point
        • Have collected 20 ratchet wrenches so far
        • Why? Broke one and wanted to try out all the different styles and brands before buying a set
        • What are we testing?
          • Thickness of the wrench
          • How does it feel?
          • Max torque to either failure or cam out
          • Any other tests?
            • Thickness to torque rating
            • How much mechanism play
            • Measure ratchet dimension
            • How?
              • Quick tests show I need more than 100ftlbs but less than 250ftlbs of bolt torque
              • Load cells to measure the clamping force between 2 plates
              • Need a “screw” drive to handle the force
              • A normal ½” bolt is usually 5/16-18” which handles ~30ftlbs before pulling the threads
              • Two Paths
                • Take a ¾” bolt and machine the head into a hex
                • Take a ½” allen socket with a ¾” square drive and attach that to a bolt

                  • Automate the Boring Stuff

                  • Spending 20 hours to save 1 - the engineers life
                  • Making API calls with the requests library
                  • Requests: HTTP for Humans
                  • Openpyxl for creating excel
                  • Commenting code
                  • Automate the Boring Stuff
                    • ...more
