Here are the files for some nucs. They make FOUR – 5 frame NUC boxes from ONE – 4 x 8 sheet of plywood. These have a 1 inch hole in them for bees to come and go. Use either a canning jar lid or Model#279 Metal Disc Entry available from kelleybees.com as a closure. Both methods are discussed in Swarm Trap Plans – 10 Frame Lang Deep.
I haven’t made any of these nucs yet, but here are some pictures of what they will look like. Just envision them without any hanging board on the side. Once I get some made I will update these pictures.
