    Default Top Bar Thickness

    I just realized that the top bars I cut are 1" thick will this matter in the end? The plans I'm using indicate 3/4 thickness".

    Thanks,

    Rob

    Assuming that the 1" thickness you mention is in the vertical direction when the bars are installed in the hive, then there is no difference compared to 3/4" thick bars. If you have a flat roof resting on the bars, it will be 1/4" higher than otherwise. If you have some kind of hinged/peaked roof, of course you need to check that your roof design will work with the thicker bars.

    Super! That makes sense.

    Of Course I'm suck a rookie that the wood is actually 3/4" thick. My bigger problem is that the wood I bought displayed a size of 1 X 12 and it's actually 3/4 X 11 1/4. Should I ensure that they are 12" wide or will the volume be affected?

    TY,

    Rob

    All lumber in the US is about 1/2 inch smaller than the size claimed at the store. It originally is the exact measurements as rough cut, but will milled it will be smaller. I think the exception to this is 1 inch thick would which is 1/4 inch smaller.

    So a 2x4 is really 1 1/2 x 3 1/2.

    Hope this helps

    If this is in reference to the sides of the hive, then its fine to use what you have already. Very few dimensions in a TBH are critical once you get the width of the bars correct.

    The difference in
    USA/Canada lumber between nominal and actual lumber measurements changes depending on board size. Here is a reference:

    Note in particular the change between 1x6s and 1x8s. I got fooled by that in building my first TBH when I assumed and didn't measure!

    Radar - I had never picked that up. Would have gotten me as well.
