    Default migratory tops

    So they say there's no dumb beekeeping questions, so tell me what the real purpose is for the wood cleats that run across the narrow width on the top of the migratory tops? Obviously, I don't use migratory tops.

    To keep them from warping and becoming unusable.

    Great question, I've wondered about that myself. I thought the cleats might be for leverage to remove the cover without damage.

    How do the cleats on the ends prevent warping?

    The cleats act as a guide when stacking pallets. The bottom deckboards on our pallets sit right between the cleats.

    By adding the strength of an additional piece of wood which is normally cross grain to the top.

    OK, makes sense. Especially with plywood. I get it now, took a few minutes to sink in.

    Are most migratory tops made with plywood these days?

    It is very hard, if not impossible, to find boards wide enough to cover a super seamlessly. Plywood does.

    Since it's broadly worded ''Migratory tops''


    Does anyone have a design or know of any plans for a migratory top with an upper entrance?


    Thanks in advance.

    From Michael Bush's website.

    If you use standard migratory tops with cleats on the ends, you can slide in shims on the long side of the box to create an upper entrance.

    Or, if you cut your plywood top flush without cleats, you can add shims to the end to create an entrance.

    Mine have. 3/8 plywood 16 1/4 X 19 7/8". A 5/16 X3/4" rim all around with end pieces having a 2" trapezoid cut out and pivoting on centered nail. the ends have 1/2 slices of scrap 2 by X for stiffeners. They are mostly made of scrap and you get ten out of a sheet of plywood. I am not smart enough to post pictures. They have some downside but I just can't seem to quit making them. I like the versatility.

    If you make migratory tops out of plywood, is there a paint out there other than latex that would hold up better to coat them with. I have made tops of plywood for some top bar hives in the past, and even with several coats of latex it will start getting fine cracks in the paint after several months, thus allowing moisture penetration into the plywood. Then again, maybe that's just the nature of plywood and no paint will keep it perfectly sealed for very long.

    Use Advantech. Lasts a long, L O N G time. No painting required. Usually get mine as scraps from builders....

    Advantec, an engineered plywood-type sheet, does not warp. It's a little pricey but is also thick enough that you could rout a groove into it for a top entrance.

    I add a 3/8" X 3/4" wide rim on my plywood tops, similar to what Vance was describing. Three sides are glued and nailed down. The side that will be used for an entrance will be nailed with no glue so that sections on the entrance side can be removed or replaced as needed to control the size of the opening. Most of my tops have entrances on the long side, some on the ends as in the photo.

    With that extra space above the top bars, don't you get a lot of burr comb?

    I use these as a combo top and bottom. Sometimes a put a piece of vinyl flooring on the top bars (an inch or two away from all the edges)....... keeps them from building burr comb above and sticking the top to the frames........

    Cut a piece of vinyl flooring and lay it on the frames (an inch or two away from all sides)........ works like a charm..
