After getting a hive, suit, smoker, hive tool (kindly left in my garden by a friend giving up beekeeping and now filled with bees) I've now bought another complete hive with frames etc as I soon realised you can't get by with just a few extra frames but was wondering what else I need. What can't you live without?
Seriously, you should already be thinking of better-than-standard queen excluder, cover board and clearer board.
A framed (for your National) rigid wire queen excluder is so much less hassle to remove and replace for inspection. Use one and you'll start to loathe the galvanised or plastic sheet-type.
A no-hole see-through beespace-framed cover board is a really great upgrade. You can SEE what the bees are up to without opening the hive.
Then get a cheap plastic Rhombus 'escape' (£3 ?). Make your own clearer board to carry it from thick marine ply. Give it a taller frame on one side (for the Rhombus) and a standard beespace on the other, then, when you take off the Rhombus and flip it over, you can use it as a feeder board. Because you got thick ply, it won't sag under the weight of your feeder.
Both Rhombus and feeder will work nicely with a single large circular hole in the middle of the board.
Don't trust Porter escapes! Try it. See if they stop bees coming 'up' for you. Then make your Rhombus/feeder board! (Or get someone to knock one together for you, but its easy enough for me to do.)
