I have a lot (well, for me) of honey supers with drawn comb, but would like to run small cell bees if possible. All of my bees are cutouts or swarms or splits, and I don't treat at all. My thought is just to use the triangle top bar as the top of my langstroth deeps. So, basically I'll checkerboard my current Langstroths with some where I've stapled a triangle piece of wood just at the top inside of the langstroth frame. From there, I expect the bees to draw down their own comb.
I don't spin my deeps, so I don't feel like I have to reinforce them with wire or a plastic foundation. Plus, the wax used for brood is stronger should the bees eventually put honey in it.
I think this would be the best of all situations: I have plastic foundation for my drawn supers. That's the best scenario for extraction. In the brood area, I would have 100% natural comb, but still within the frame. That allows me to cut out the wax easily for recycling. As it stands today, it is very hard to recycle a plastic based comb. I have found that wax moths do the best at cleaning those frames down to the plastic, but I don't really want to breed a bunch of them, and they do tunnel through the wood bound frame.
I have 2 top bars and plan on adding some more, and have both 10 frame deep langstroth and 8 frame shallow langstroth, and an observation hive. I like to experiment.
One other question. When might be the best time to try this? I think if I try it now, I'm going to get a lot of drone comb. Do the bees tend to taper off drone production after the spring?
