dAVE, IT DOES LOOK COOL TO ME TOO. (oops sorry for caps) Thanks!
I think i'd be more inclined to make a wooden trough though- it's not that hard! Wood looks so nice and may have better ventilation/insulation qualities for the bees, especially in winter. TBH's are pretty simple to build, maybe even simpler than working with this plastic drum- I watched Sam Comfort build one once from scrap wood very quickly and easily.
What kind of questions do you have?
I'm not an expert, but I do have two TBH's that are doing great. And I have stayed in a Holiday Inn several times.
I like them as they seem to be easier to manipulate and inspect. Mine seem to build up quicker than a lang.
I started one in October of last year and it filled up and swarmed in March. I was lucky enough to catch both of the swarms that it threw off and started one lang and another TBH. I have the four foot model.
