Thread: Interesting, Odd or Funny Pics.

I was admiring a turbine disk from a small gas turbine at Avalon air show a few years back. The hub and blades were one lump of metal. I asked the rep. how they were made. "Friction welding" he said. He then explained that the blades were held against the hub and vibrated so hard that the metals fused at the junctiion. Pretty impressive result.

I remember a story that made the Melb newspapers in the early mid 00's when I lived there.
An enterprising vigilanty group of fellows would rescue clamped cars for free basically by stealth and in lightning quick time.
Their method? LPG cutting torches and air shears.
They would cruise the parking strips in an unassuming vehicle and when they noticed a clamped car, pull in and rescue it. I believe it was a quite sophisticated and slick operation.
It made the news because the clamp company complained to police that they were having many of their clamps stolen and destroyed!
