Just a thought,
A feed rim and a flat migratory cover.
One side is the feed rim and the other side is for the patties.
The feed rim side has 3/4" plywood on both ends and a 2" wide plywood side for stability.
Just flip the cover for it's intended use.
August -September use the feed rim side...
I am making 3/4" feed rims so that I can feed pollen supplement and or pollen patties for population increase.
I am putting feeder pails on the bees too.
The syrup for filling the pails is a heavy type. (2:! at least) For those that read this and need to know what a 2:1 ratio is it's two parts...
