cheapest place for natinal crown/feeder boards

when using matchsticks

I don't, unless under the brood box (and then matchsticks would likely crush, so I would use something a little more robust).

Most of my colonies have more than adequate ventilation at the floor level without recourse to any other tricks.

RAB, it is quite likely that many readers will not know that you use *top* beespace hives.

You are right. There will be some that don't know the difference. Not my fault if they are unable to work out the difference? They clearly need to actually read a beekeeping book? Oh, and understand it? They could always ask why, if they could not work it out; there is enough on this forum to give some broad hints. Sometimes people need to think. Clearly you think there are some that don't?

I do think there are some that might read this forum without realising that a 14x12 can be built with non-standard top beespace.

And I believe there are some that would consider that if it was worth mentioning that you use un-battened coverboards, then it might also be worth mentioning why that was possible, given your stated hive type.

I'm sure you wouldn't intentionally try to catch out the trusting novice, would you?

As can a National and a super.
My first boxes were standard national flatties from T h o r n e s made up with TBS

I make mine from whatever ply is available from local offcuts and put batten round. If the Op doest want to make them they usually cost about £6 each it the Tho r n online sale which is due sometime in November.
