I know you all know the term 'jury rig' (and sometimes 'jerry rig') for making a quick, temporary repair.

Well, I was just surprised to read of other applications of quick repairs:

jury mast (to repair a broken mast with a temporary replacement)

and:

jury rudder (You can figure that one out.)

However:

jury wheel...didn't follow suit. It was a simply a wheel with names of potential jurors from which random names were taken after spinning the wheel.
