    Default Does anyone know what size these slots are?

    I'm building a homemade nuc entrance disk like this. Would anyone know what size these slots are in imperial measurements? Thanks in advance.

    I tried 6 times to get the image to upload in the message but it wouldn't do it so below is a link to my drop box.

    Since you didn't attach a photo, my guess is the size is "small".

    Some are smaller than others, I finally gave up and put a link to my drop box.

    Slots in an entrance disk are usually queen excluder width and larger, like for mouse exclusion. For closure ventilation it is usually little holes.

    Thanks for your reply O.F. but I don't have an example on hand and all the dimensions I found on line are metric.

    Why don't you pass those metric dimensions through a converter to see "Imperial" dimensions?

    Your photo seems to work OK like this for me ...

    I guess I must not have been patient enough.

    I tried loading that image again from my desk top with the uploader and I keep getting a red explanation mark with a 404 error message.

    I finally did the conversion and then all the math and I get about 3/16 or 11/64 th's

    It has to be more accurate than that to work.

    .163 inches or 4.1 mm is roughly 21/132.

    Many of the measurements on Dave Cushman's site are metric/imperial.

    Here is a conversion site.

    Personally, I use a caliper and a ruler that shows both, so I never really need to convert, I just use whichever measurements are given in the plans I'm using, or measure the item, myself.

    P.S. It's easier to attach images by linking, for instance the dropbox image URLs, instead of trying to upload the images to beesource, directly.

    How much use does anyone have for queen excluder slots on a disk anyways? I do not have abandonment problems. I am not importing or raising AFB's. I am not trying to contain bad drones. If I was raising queens why would I want to keep one in? Oh! Swarm control?

    Somewhat

    odfrank,

    Sometimes I use queen excluder size openings to protect my breeder queens in their nuc colonies from possible AHB usurping. I've actually witnessed this work successfully, several times. Usurping is my least favorite AHB trait. Other traits can be remedied by timely requeening, but, thank goodness for marking paint and Cordovan genetics (I mark the queens I produce, as soon as they begin laying).

    My most recent usurping experience: Just after I finished manipulating one of my breeder queen colonies, to harvest grafting larva, I noticed a golf ball size cluster on the side of the nuc, adjacent to the excluder protected entrance. Using a piece of shim wood I flicked this cluster off, yet they kept returning, After the fifth or sixth time I watched carefully, as they reformed, spotted their queen (she was unmarked and had the size and appearance of a virgin), I caged her and set the cage aside -- take-over thwarted.

    Hello O.F:
    I was figuring to use it when catching swarms to keep the queen from leaving if I managed to get her in the nuc.

    Colino,

    Queen includer, sounds like a very worthwhile use.

    I used the discs on a couple of nucs, and the openings seemed to be
    undersized,,,only the smallest of bees could make it through the slots..
    used it for ventalation purposes as the hornets were trying to have their
    way at the front entrance which I reduced, but the hive seemd to
    heat up...Mine were the small metal ones, but I havn't used the larger
    plastic ones...

    I have several of these Mann Lake entrance discs (HD 596) in my garage and a digital caliper. Measurements for the QE slots are: 0.158 in


    I also have some new Mann lake 10-frame QE's and the grid spacing is: between 0.163 to 0.168 in

    Thanks I'll dig out my son's digital caliper and I think I will try 0.165, hopefully that will cover all the bases.
    And thank you everybody else for your replies.

    FYI if for example you Google "4.2 mm in inches" you won't even have to enter the query to get the answer. Google will convert almost anything to any equivalent measure. Horsepower to BTUs per hour, cubits to parsecs. It won't tell how long it takes to do the Kessel run though.
