It`s just a piece of 10mm ply (318x240 IIRC) and a some offcuts of cedar i had laying around. I spent awhile working out the first one but once you have the measurements i could cut all the pieces in 5 minutes.thanks, is all that timber your own extra work?
I think you could use the smaller Langstroth nuc box for standard national brood frames, but i may be wrong, never having seen a Langstroth frameI would also need a block on the base as I run mainly standard national (but do have some 14x12 too.
Yes they do, and they can supply a central divider board to enable two 3 frame nucs to be in the same box. I am currently using one with 14 x 12 frames (on converters) and a Langstroth frame feeder that they also supply. Due to the current wasp situation, I also have the entrances reduced.Do rooftops poly nucs have two entrances? one at each end.
