This brings up a question for you machinists out there.
I once watched a program on the Discovery Channel which showed how
rifle barrels are made. It said in order to drill a perfectly
centered hole in a rod, you clamp the drill bit stationary and rotate
the rod as if it were the drill bit. Done this way, the rod will
automatically center itself around the drill bit.
Is this true or just an old (machinist's) wives's tale?
