My brother went into my bees the other day to transfer a couple of brood frames into his hive. He found out 2 things, 1. bees get nasty when being brushed off of brood frames, and 2. making sure your veil is tied right prevents the mad-man, raving lunitic, dash.
I gave him a lesson on proper tie down of his veil, then fixed his table saw (electrics) while he finished up my 4 section 12 frame queen castle. Now to paint it an put it into operation building nucs and breeding replacement queens.
