I started building pallets for my bottom boards. This one holds eight, eight frame hives. The spacers that lift it off of the bottom are one by boards. All of them are generously wide to allow some leeway in the way the box sets on them. If I push the boxes all the way to the front I have a space to get my hand in the back. Come winter I can push them tight together. I started building these because I was running out of bottom boards and because I now have a tractor and I can pick them up with the fork lift on the front end loader and move things around.
I consider propolizing a good trait for bees (maybe not for the beekeeper). Here is a mating nuc I found this year. The drilled hole is about 5/8". The reduced hole is about 5/16".
It wasn't working right and then it would and then it wouldn't. This is what I found. It couldn't get out, so I left it and used another smoker. It was finally out after two days.
We needed to feed because of a dearth and we still needed to finish building up the 8 frame nucs for winter. We bought 50 six gallon buckets and bought 3,450 pounds of sugar in 25 lb bags. We worked out the maximum strength we could do with hot water from my tap (140 F) and not have it crystallize out. We put one 25 pound bag in each bucket with a heaping tablespoon of ascorbic acid, then 18 pints of water and stir it with a five gallon paint stirrer. After 10 to 30 minutes we stir it again.
