  3. 3. Why Have a Hive Scale?• You can see the current weight and the rate of change, and make inferences about the state of the colony• What’s going on in there? – Is the hive full and the colony about to swarm? – Is the hive empty and the colony about to starve? – Is there a nectar flow or should I be feeding?• Does the colony need: Another super? To be split? Some feed? Today? Next week?• To provide data to: http://honeybeenet.gsfc.nasa.gov

  5. 5. Make the Hive Scale• Buy: scale, mirror, base, blocks, tape. <$20• Paint: base• Glue: mirror to scale• Tape: gaps in scale – What happens if you don’t• Assemble: – Put blocks on base – Put scale on blocks – Put hive on scale• Monitor: hive weight. Gain: insight.

  7. 7. Set Up the Scale
  8. 8. Mirror Purchase a cut-to-fit mirror replacement kit from a car parts store.
  9. 9. Cut & Bend the Mirror Cut a strip of mirror material the width of the dial. Bend the strip over a sharp edge. It may take some force. It may help to have clamps or a vise. Test the angle of the bend by looking at the dial using the mirror. The numbers on the dial will appear upside down. You’ll get used to it. Attach the mirror to the scale using the strips of double sided sticky tape included with the mirror.
