@JeffH don’t you ever remove a comb for inspection and have a breakage/leakage due to brace comb, etc?
I only say I think many/all people will have some leakages- because we had leakages both times we operated the flow frames. Also I have watched videos of people operating frames on youtube- including the one where Cedar operates one outside a hive- and it looks to me like I can see honey leaking in the background…
By doing it incrementally- i think we only lost a few tablespoons last time (7+kg’s harvested)- the amount is insignificant compared to what is harvested. Obviously the honey viscosity will play a role too- and possibly the tightness of the frames wires- and the state of the capped cells. If there is an uncapped section- then there will probably be more leaks. For this reason it is important to check the frames carefully before installation to make sure all the cell rows are in the closed position.
We are new to beekeeping- I don’t know about any issues with robbing this leakage may create- or how annoying/damaging it is to the brood to have honey leak down over the frames and out the bottom? I would be interested in what people think about this. It seems like the bees manage OK- being able to quickly lick up spilt honey… But I did hear our Queen ‘piping’ when we harvested once- not sure if that was a protest? The bees never became angry and the hive settled quickly post harvest.
I (like some others) am thinking of making a horizontal langstroth/flow hive- one advantage to this design will be that leaking won’t be an issue for the brood at all- and could be very well (totally?) managed- if you can slide a tray under the flow frames during extraction.
