In one way, the Cloake board is one of my favorite pieces of beekeeping equipment...the inventors name was "Cloake", and the device actually "cloaks".
....but I've never owned one or used one. I do, I think, understand how they are used and why....on more than one occasion, I've done the same thing but by separating the bodies and putting a board between.
I have no criticism for using a cloak board....I write this because I was thinking about making some. But when I really think about it, does it really eliminate more than 3 minutes work, and a little bit of disturbing the bees over just using a board?
Regardless, I might build some for my own use, but I'm thinking this would be really low on the list of things that someone needs to acquire before they start rearing queens. Am I missing something?
