Secondhand Scoreboard
The scoreboard that I just installed in the 303bnb was missing its second hand. As you can see in the pictures, the broken 6-32 screw was barely visible inside the sheath of the minute hand.
To get a hole properly centered in the broken shaft I had to make a guide from a piece of aluminum, The guide slipped over the broken shaft and made it possible for my 2-56 tap drill to stay on course.
After tapping both the shaft that the replacement tip, I screwed in a small piece of 2-56 threaded rod with some red locktite. It looks as though it was never broken and has the strength to last another 70 years.
I used a photo that I found online to recreate the size and shape of the original second hand. Check out the install post to see it in all its glory.
