This discussion about foundationless frames has really been very helpful to read, as I am just preparing to make my own material for the brood box from scratch. I was going to have just the top bars, cut with a V-shape towards the bottom. No side or bottom bars, kind of like in a top bar hive, but with spaces between the bars.
Now here is the question: If natural worker comb is 1 1/4 inch on center how wide should I cut the bars? Michael Bush recommends (as I understand) for the frames to be 22 mm wide, with a spacing of 10 mm, which makes a total of 32 mm from center to center, which is pretty much exactly 1 1/4 inches. But my Langstroth frames are spaced almost 1 1/2 inches from center to center. Is the Langstroth measurement thought mostly for commercial bees? If I want smaller feral bees wouldn't it make sense to make the bars narrower and have the combs closer together? I've read this would be better for mite control, heat preservation, etc.
Can anybody tell me if my thinking makes sense, PLEASE?
