I have some lumber laying around and I'm thinking of making a few nuc stands. Stands of parallel rails, long enough to hold 4 or 5 nucs, raised off the ground 24-30 inches in order to keep them at a workable height. I just realized that if I set these rails apart about 18.25 inches the nuc stands could do double duty as frame racks when not in use. I'm finding the need for a frame rack as I'm sorting and grading my combs of brood comb.
