I am getting ready to make some progress on my first larger (250) batch of medium frames from scratch, simple question.
How far should the wider portion of the end bar go before it narrows? In my experience this (the fatter upper portion) is where the bees propolise the frames together, wouldn't I want it to be only far enough to facilitate handling multiple frames at a time? Like say 2"?
The "BIY" pdf plans for Dadant style frames here on beesource suggest 2 5/8 for medium frames" Anybody have any input?
