Interestingly i’ve had a few queries about these frames, so thought i’d post this image from anyone that hasn’t come across Ideal frames before (sorry can’t credit the source of the image… think it was an eBay ad or beekeeping site).
Alliance from NZ make nice quality wooden Ideal frames (wooden frame in my extraction photos), there are also a couple of suppliers in QLD who make them. Unfortunately they aren’t as popular as I wish (and they once) were… but they have a great list of benefits! eg. I have an ideal box between my brood box and Flow super so the bees always have some stores available but I don’t have to dedicate a full depth super.
