Cliff, too bad you didn't stop right after the word "correct." Pal had it
right, so "correct" is correct. But swing is not a radius. The radius of
the maximum size his lathe will turn is 3"--the swing is 6", the DIAMETER.
The illustration of a swing hanging from a tree merely adds to the error
of
calling the radius the swing.

'Swing' is the radius, not diameter. Think of how long a pendulum would be
swinging from the spindle. Same wrt crank length on a crankshaft.
