This is a common repair I make on boxes. The frame rest will get broken or chewed out by mice. It's not usually the rest, but the back of the rest that break out. After removing any nails or staples or screws that might be in the saw path, I set the fence at 3/8" and the depth at 1 1/2" (or whatever the one by two is in width) and run all of the boxes through the table saw. Then I set the fence at 1 1/2" and the depth at 3/8" and make the second cut. Then I glue and screw the one by two into the space I cut out. It also makes a nice handle...
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.
