When I first started beekeeping, I needed supers, but was averse to the high price at the local beekeeping supply yards. I managed to find some moderately cheap wood, and built 30 supers. It's been about eighteen months later, and a good proportion of supers are splitting apart, as show here: http://imgur.com/a/cO6av This is my first beehive. Every super needs to be replaced, including the lid. I'm concerned about the holes as there's a lot of heavy winter rain currently. I've established a practice of using duct tape to seal the hives, but it's not particularly effective. Another hive's super was so damaged at the bottom, that it fell apart when I tried to replace it. It seems after about a year, the lowest supers start to split. It seems that they're unable to sustain the weight of a multi-story hive. A local said that this sort of damage might be caused by these slight elevations the hives are on; causes an excessive amount of pressure on one side, but I'm unsure. Is it important to place beehives on flat elevations? Another particular concerned is that almost every lid I own is quite warped for some reason, and has gaps exposed because of so. I've learned that the "woodsman's glue" from the local hardware store was not effective in holding together the wood for a sustained period of time. It was all shriveled up and not sticky. I used an excessive, sloppy amateur amount of glue for the most part as well. The nails that I used weren't long enough either. I've been advised to use screws instead, which I'm in the process of installing screws on all my supers, including the ones with bees in them. Screws are much more expensive than nails, though. It's almost mid winter here, and I still haven't found a cheap source of wood; I'm left wondering what's the best way to proceed. I've been advised to build hives out of more or less freely available chip-board, simply "slap on a thick coat of paint". I feel as if this will create future, bothersome scenarios in the future, but may be suitable for the lid and/or top super(shallow supers?). I fortunately have acquired all the screws I need. I'm not going to buy that woodsman's glue again; not sure if I should look into another. I do wonder if that glue simply isn't meant to be so exposed to the elements. Has anyone else had their supers split, and lids warp like this?
