    Default weighing hives

    Need some help figuring out my hive weights , not sure if my method will work for actual weight or just for comparing my own hives . My hives are on a 2x6 frame which is sitting on concrete blocks . I have the three hives sitting with the bottom board hanging over the back edge about an inch , just enough so I can put the S- hook on my scale under it and lift the back of the hive about an inch off the rack . All 3 hives are the same two deep brood boxes except for hive number one has two honey supers still on so its going to be hard to compare that one .Hive number one 2 deeps and two honey supers with honey 75 pds , hive number two just 2 deeps 50 pds. and hive number three just two deeps 85 pds . There seems to be quite a difference , can anyone shed some lite on this or should I be weighing them from the side , problem is I have support pieces running in the way for side weighing .

    I am surprised the hive with the honey supers is lighter than the 85 lbs one.

    Ideally, if your stand is level, the back weight should be approximately half the weight. To test, place a bottom board or similar on the stand (if you have space) and a known weight (bag of dog food or similar) and see how close to the half point you are by weighing in a similar manner. If you are close, I would be worried about the lighter 2 hives as they are too light for double deeps and esp the one with the supers.

    Ok , I'll give it a try with a known weight , good idea, and see what I get , I'm surprised too because that was my strongest hive from the start and the only one giving me any extra honey !

    Laketrout,
    I weigh mine by your method -putting the scale under the back and lifting. Then I double the reading. I never checked the accuracy but this ain't rocket science.

    I have such a wide range of weights was wondering whats going on , I checked it and I'm getting half my hive weight almost right on the button . So that means hive #1 is 150 pds minus the two supers and any honey ,, hive two is 100 pds and hive three is 170 pds so how do theses weights stack up for winter stores. I did notice just by feel that #2 was lite and I have been feeding it .Hive # 1 is a complete surprise I don't know why its so lite .

    Laketrout it isn't rocket science but maybe 8 grade science. If you want an accurate weight you must weigh two opposing sides and add the results together. the reason is you have no idea where the weight is concentrated. It could be in the front the back or one side. I would assume it is never symmetrical and I suspect that the big difference you see from one hive to another is because it is not symmetrical. Take the time to weigh two opposing sides and then make the comparison.

    Thanks Acebird , I'll weigh the front tomorrow and see if if the numbers make more sense .Would the over hand-hang front to back on the bottom board have to be the same or won't it matter.

    laketrout, what is the size of the supers? You can also hook to the back and front of the supers themselves, too.

    I'm using two deep brood chambers on all my hives and med. honey supers as needed . Where are you hooking onto the boxes , are you getting under them .

    I am thinking you should be able to hook under the edge of the bottom super. In this way you'll know what's in the supers and the brood boxes.

    The bottom boards don't weigh much I could subtract there weight after getting a total weight , its much easier to lift from the bottom board .

    I figured out what the weight difference was with the added length using the front of the bottom board some time ago, and it is so little I don't think it matters. To check you could make a bridle that slips around under the bottom board and that would allow you to weigh the front up close to the hive, then weigh again with the added 2 inches and see if you notice a difference. There would be a lot of strain on that bottom board so make sure it would be able to handle that pinching of the bridle.

    If the hive was perfectly symmetrical meaning the weight was directly in the center of the hive you would see a difference between the front reading and the back reading because of the overhang. That doesn't matter because the true weight of the hive is the sum of the two readings.

    Think of a bridge that has a support on both sides of the creek. If there is 2 cars on the left side and non on the right side the left support will see more of the weight of the cars then the right support. But the total weight of the bridge and the cars on it will be the sum of the weight of the two supports.

    Not the average of the two readings? Somehow, taking the weight of the front and the weight of the back and adding the two to come up w/ the total weight of the hive doesn't jibe in my brain. But I'm not good at math anyway.

    "jibe", I think it means balance out or make sense. "jive" is disinformation, I think.

    Not the average.

    Mark you can prove it to yourself with two bathroom scales. Step on one with both feet and weigh yourself. Now put one foot on one scale and the other on the other scale. The sum not the average will be your weight. If you hold a 10 pound weight in one hand and hold it out as far as you can reach one scale will be more than the other but the total will be your weight plus the weight in your hand.

    But that isn't what you wrote about in your previous Post, was it? I thought you recommended weighing one end of the hive and then the other end and then adding the two together to get the total. That would be like me standing on the scale on one foot, recording the reading, and then the other foot, recording that reading, and adding the two together.

    I weigh my hives by weighing one end and doubling it. I have tested the theory with a known weight on a bottom board. Weighing either end and doubling it is very near accurate. The error is insignificant. I have off set the weight to one end and weighed it too. It still comes very close to the "true weight" by doubling it.

    Think of the side not being lifted as "the other foot"...on a scale you can't get any data from.

    I'm gonna go beat my head against a brick wall. You tell him to weigh the hive from the front and then weigh the hive from the back and add the two measurements together to determine the total weight of the hive?

    Then you say the weight of a bridge is two cars and the weight of the supports?
