B&C Spectrograph Measurements

Weight

Weight of spectrograph: ~80 kg
Weight of lift bar assembly (4.5 kg) = weight of removed collimator (4.7 kg)
"Zeroed" scale reading: 5 kg

The spectrograph was mounted on a spring scale and chain hoist. The spectrograph usually rests on its cart with horizontal pins. The chain hoist was pulled until the pins lifted in their seats. After settling, the weight read ~85 kg. Since the collimator and the lift bar weigh about the same, and the scale was "zeroed" to 5 kg, the spectrograph weighs ~80 kg.
