While relining an induction melting furnace I saw how our ingenious machine repair had rigged up a plumb bob to center the coil. In order to stabilize the plumb bob which was inside the furnace to a depth of twelve feet someone got a 5 gallon bucket of water and suspended the plumb bob in the water. Not only did it stabilize the “bob” against the air movement but it therefore allowed a quicker measurement to be taken when centering the coil as it would dampen the movement in case the string was bumped.
