Re: Getting Mann Lake to make 4.9 plastic
My bees burr up the top and stick them to the frames above. It makes for a mess of ticked off bees when you go and open the hive and the frames from the bottom box lift out when you pull off the top box. I have been phasing these critters out, but I do like the 4.9 cell size. It would be nice to have just sheet foundation for this stuff.
Every now and then, my bees also try to draw comb on the edge of the plastic topbar, between frames so they don't have to touch the plastic foundation. Very annoying.
