A lot of my beekeeping philosophy comes from reading Langstroth’s The Hive and the Honeybee (download here for free) and Michael Bush’s website (www.bushfarms.com). They both comment that much of their knowledge of bees comes from observing them. In fact Mr. Bush states that “I have learned much more from [observation hives] in a year than many years of keeping bees in a hive.” I’m a geek at heart, and what is geekier than having a frame full of bees hanging in your office? So I set out to make my own observation hive. As cheaply as possible, of course!
Mr. Bush believes that the best space between the glass of a single wide OH is 1 3/4″ so I took some scrap 2×4 stock and ripped it on the table saw to 1 3/4″. Next I did the math to get my dimensions. The width was easy, as an 18 1/2″ inside width is just right to have a 1/4″ kerf on each side of the hive for the frames to set in. For the height I took the heights of my frames then added 3/8″ between each frame and at the top and bottom for bee space. I used 4 deep frames so my inside height was 37 1/8″. Here is my ROUGH hand drawing of my original plan:
After getting the sides and top of the hive frame cut, I used a table saw to cut 1/2″ grooves in the two upright sides. These grooves are where the frame tabs will sit. I found it easiest to cut these by putting my two side pieces together and running them both across the dado blade at the same time. This ensures that the groove will be in the same height on each side so that the comb frame will sit level. The tricky part is making sure that you leave 3/8″ bee space between each frame. I found the best way to do this was to cut a notch then lay out both sides pieces on the floor with a deep frame in the groove. Then measure down 3/8″ to mark the top of my next notch and cut it. In the end it worked out alright.
The base of my hive is a scrap piece of 2×8. On one of the sides I cut a 1″ groove in the bottom where the side meets the base. This allows the bees to walk under the side of the hive and reach a mason jar feeding station. It was built by cutting a hole the size of a mason jar lid through a 2×4 then ripping it lengthwise and sandwiching #8 hardware cloth in between the two pieces. When I attached this to the base I have a way that the bees can get to the feeder, but when I remove the jar to refill they can’t escape through the hole (see image below)
I added an additional 2×4 across the back of the frame for support and used stranded wire with an adjustable bolt to give even more support when its full of honey. I cut ventilation holes and backed them by stapling and gluing #8 hardware cloth so the bees can’t used them as and exit into my house!
To mount the hive I used gate hinges attached to the back of the hive and to a stud in my office. For an exit I used liquid nails to attach a 1 1/4″ fitting in to hole in the base. Then you can buy sump pump tubing at most big box hardware stores for less than $1 per ft. I then took a piece of 1×6 cedar fence plank and cut it down to the correct length to fit into my window slot. I used a hole saw to cut a 1 1/4″ hole in the plank and feed the tube through it for an exit. Here are some more pictures to see how it mounts and the tube exit works.
To attach the glass to the hive I’ll use mirror clips. These clips will hold the glass flush against the frame of the hive. Then when I need to open up the hive I can lift it off the hinges, take it outside, take the 2 mirror clips off the top and slide the glass out. You can get mirror clips at most hardware stores. I tried hobby and hardware stores for buying glass or plastic to use for the facing, but it was going to cost way too much. I finally tried my local auto glass store and was able to get it for $45 total! Total cost breakdown is below
Wood – Free (scrap)
Hinges – $25
Glass – $45
Mirror Clips – $8
Hose – $2
Hose fittings – $5
Total – $85
Dropping $80+ on something isn’t what I would call cheap, but when you compare how much you’ll pay for a hive similar to this it’s extremely reasonable. Here are pictures with the bees in and the glass on. See if you can spot the queen in the first pic.
