Thanks Al...wasn't familiar with that term...

"Brinell" is also used as a verb to describe what happens when a cone
or cup is marked by ball bearings during an impact. I learned about it
working in a bike shop in the early 70s -- always support the bottom
bracket axle when driving cotter pins from the cranks, especially when
working on Sturmey Archer stuff.
