Build Your Own: Queen Castle - Three Frames by Three

This is simply for reference, follow the directions for the Two Frames by Four Queen Castle. There are a few differences.

Dividers - You will need three 1/4" dividers cut at 19 1/8" x 10 1/2"
Inner Covers - Two at 19 1/8" x  4 3/4" and one at 19 1/8" x 4 7/8"

Three frame queen castles allow the queen to build out a little more, allowing the beekeeper more time before they overflow and begin swarming preparations. If you sell nucs, a four frame nuc would simply be one of these compartments, plus a frame of empty comb/foundation. If you take out a divider you will be able to put in seven frames, however it is very tight.

If you take a Solid Bottom Board  and run two dividers down the middle  to the end of the landing board to correspond with the Queen Castle dividers it can make a great landing board. I know a queen breeder that uses these, and paints each divided landing board a separate colour. I could see problems with queens entering the wrong entrance. Otherwise simple cut holes on three separate sides for entrances.
