Everyone knows the rule, “ask three beekeepers and get four answers”
Correct bee space prevents bridging comb.
Correct frame spacing prevents bridging comb.
Any vertical or horizontal gap that the bees must pass over to get somewhere greater than 9-10mm encourages bridging comb to assist the bees with access between the two. After all, they can only reach so far.
Apis mellifera like to build honeycomb deeper than brood comb. Standard Langstroth frames with the shoulders touching allow two bees to work back to back on the frames and encourages brood production, not long term honey storage.
If the bees can only store a small amount of honey in the brood frames, honey arch, they will be encouraged to use the flow frames for longer-term stores and move honey stores up into the flow frames during flows.
Apis mellifera in Western Australia appear to work well in the single brood box, eight frame Langstroth hives for non-commercial beekeepers. The bees use the inner six frames for brood and when no flow is happening or when preparing for the winter period the outer two frames for longer-term honey stores.
Eight frame Langstroth hives have a gap at the side when all eight frames are pushed together. if you centre the eight frames, shoulder to shoulder, with the wider dead space between the outer frames and the walls evenly spaced you will encourage maximum brood production and allow the bees a private reserve of honey on the outside of the outer frames.
Alternately if you centre the six middle frames shoulder to shoulder and provide an evenly spaced gap between the grouped inner six frames, the outside frames and the walls you will potentially get two double-sided honey frames that could be used for cut comb of course they will move the honey up into the flow frames and use these two frames for brood if the flow frames are available if they need to use them for brood.
One way to learn about bees is to watch them at work, undisturbed.
