Top Bar Hive Construction
Dennis Murrell – firstname.lastname@example.org
This is the plan for my Top Bar Hive. The sides consist of three 1″x6″s. The bottom consist of two 1″x6″s. It is sloped 22.5 degrees off vertical and can hold 26 top bars, which are 1-1/4″s wide by 24″s long and a follower board or 27 top bars. The sides, bottom, and ends are cut to size and then glued together before assembly. Materials needed are:
Qty – Item
7 – 1″x6″x6′
3 - 2″x4″ studs
3 - 1″x4″x6′
1 – 26″x36″ plywood
1 - 23″x36″x1″ insulation
I’m still toying with the idea of a sloped cover rather than a flat one as planned and haven’t built the follower board. I have about $36 invested which is about 1/3 the cost of an equivalent conventional hive. Paint will have to wait for warmer weather.
The bottom consists of 4 pieces. Two 1"x6"x33-7/8" planks and two 2"x4"x11-3/4" cleats.
The bottom pieces are glued together. Then the edges (along the length of the board) are beveled at 22 degrees.
The cleats are glued and nailed on the bottom planks. They should extend beyond the end of the planks 3/4" to accommodate the hive end pieces.
The end pieces are glued together and then trimmed to final size.
The end pieces are glued and nailed to the bottom.
Three pieces are glued together to make each side. Then the top and bottom edges are beveled at 22.5 degrees. Double check the direction of each bevel.
The two sides are glued and nailed to the bottom and ends.
The vertical support piece is glued and nailed into place on the topbar.
The T shaped topbars in place with space for 10 more regular top bars and a follower board.
The hive with the topbars in place and space for the follower board. Various or different width lumber can be used. The 22.5 degree slope is easy to maintain. Just angle the cut to remove a slice 1/2 the width of the lumber.

This shot taken from the rear of the hive, shows the cluster of bees on top bars 1 through 9. It's interesting to note how the bees hang from and work the edge of the blank starter strip. Posted: 18-May-2003
From the rear of the hive, top bar number 5 had the largest amount of drawn comb. Top bars 6-9 had no drawn comb. Notice how the bees hang from the edge of the starter strip and not the topbar. Comb is constructed below the lower edge of the starter strip and then the bees at some later time construct comb from that lower edge to the top bar. Starter strips, especially blank ones, may not be a good idea. The cells are visibly larger than small cell size and the Y's are oriented horizontally. Posted: 18-May-2003

A shot of topbar number 3. This topbar was the last with drawn comb although the cluster extended to the front of the hive. The Y's are oriented about 15 degrees below horizontal in this comb and the cells are larger than small cell size. Posted: 18-May-2003
