The "Forever" Golf Tee

The spike sitting on the sticky note in the photo appears to have began life as a 1/2-13 x 3 hex bolt but was worn down inside what is referred to as the "Tower Mill". The mill is auger driven and uses 1" balls to grind down whatever is left of the ore into essentially dust. Ocassionally, foreign objects like above enter into the system and are found during PMs.
