yup agreed. I build the vast majority of my bee things but this is one i dont think ill tackle.While i build most of my stuff i put the brakes on at pollen traps. mostly concerned with making an error and having serious issues detrimental to the bees. they normally have problems adjusting to them from what i've read so i wouldn't be able to tell the difference. Ended up just buying one this year. Here are some plans though.
