Picobrew, that's an interesting hive design you have. I'd like to hear more about it and maybe see some pictures from different angles, inside etc.
I believe I can post a few links without highjacking the thread or starting a debate about top bar hives.
When I started reading about bees and beekeeping a stumbled upon the concept of the top bar hive. It sounded right for me at this time. I've made errors but I'm still pleased with the concept and intend to construct 2 additional hives this winter. I stuck pretty closely to the free plans available at a website I don't seem to be able to mention by name. If one searches for top bar hive UK you can find it. I also spend time on the forum there. I use the same handle so you could relive my growing pains if you wish.
My largest hurdle was not having anyone local to ask questions specific to this hive type.
Here is a link to a photo album. album
