Had a failed top bar before. Now have an inherited Langstroth that we ignored for a few years. Starting Layens after hearing Dr Leo and taking his seminar.
We have a group of people each starting with 1-2 of these. And another group locally just did 52 and are starting on another 50.
There is a guy in the NE that does 200+ of the standard Layens by himself. Can't imagine doing 20,000+ lbs of honey
