Thanks michael,
I'll remove the bottom strip of foundation. I wanted to get away with not using wires, and hopefully crush the combs every few years to rotate them out, getting the wax. I guess Ill see how carefully I can extract. I used a motorized extractor last season and blew out a few combs, but this year Im just using a secondhand hand cranks extractor. Foundationless brood frames I already put into the hive in the brood nest are the first frames I built and don't have the bottom strip. I was hoping they would just fill out to the bottom and be ok enough to manipulate to examine. I was amazed at how strong the comb was when I took one out to see how much they had built out, but would imagine the weight of the frame full of brood would be easier to break the comb? Ive worked with wired frames, but haven't started any out myself. Are wired frames significantly stronger or should I be ok to gently use unwired naturally drawn comb?
