The total hive weight can be found by weighing each side (with a tension spring balance or a shallow platform scale), (just lift it clear of the ground and no more to avoid error-the more off level the hive is when you take the reading the more error) and adding the weights together.e.g. weigh one side =50lb, weigh other side =40lb, then total weight is 90lb There is one proviso - when weighing each side, you must weigh at the "ground support" point. Usually the hive supports are at the outer edge and this is not a problem. However if the floor has supports, inset from the edges, then it is a problem. Remember the trick is to weigh at the support points -you are finding the force with which the supports press down on the ground- add them and you've got the total weight I've made up a weigh-hook from a piece of 8 mm (5/16") x 750mm (30") rod with a 50mm right angle bend at one end to hook under the hive support (hook up the last 10mm to prevent it slipping out) and an acute bend at the other end to take the hook from a 25 kg (50lb) spring balance. This allows the spring balance to be attached a bit nearer eye level. Keep the hook/spring balance as vertical as possible. For heavy weights, keep your back under the support and get someone else to read the spring balance Alan Riach Edinburgh :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: -- Visit www.honeybeeworld.com/BEE-L for rules, FAQ and other info --- ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
