thanks for that- those seperators are interesting- I will check the measurements on my design to see if they will fit. PM me if you can get a price for the vertical exluders.
For my long hive design I used a variation of this solution to the inner cover - though I didn’t use as many ‘cover bars’ as Joe did. I think Joe’s design is the best I have seen for a long langstroth. It’s brilliant.
My hive is not as long either- and is specially designed to use flow frames- you can also stack standard supers on it… I hope to have the first few built in the next two weeks- I am racing to be on time for swarm season. Noticed more and more bees around adelaide last few days… some of the stone fruit trees are already in blossom.
