I grew up in the bee business in Northern California. My dad had 1,200 hives and my uncle had over 1,000. I ran 800 of my own hives in the 1970's & 1980's. The closing of the canadian border because of mites (no longer closed) all but shut down my queen business and low prices on everything else lead me to leave the business. Now that I'm retirement age and prices seem to be WAY up I'm getting back in, but on a small scale.
When I was 18-19 years old I made all my own custom woodworking equipment for making beehives. Lock corner (finger joint) machine, double end saws, multi hole drills and more. I now own timber land and have a small mill so I figure I would get back to making hives to supplement my retirement.
Looking around I see that other hive manufactures are all touting "full top joints", "blind Rabbets", "Full top corners" frame rests as the latest innovation for a stronger box. I was making mine that way in 1973. I would be interested to know if I was the first to build boxes that way?
