SwarmPatrol.com has participated in the crowd funding project to develop a Top Bar Beehive which can be easily cut out using CNC router technologies and then assembled without using any screws. More details are available at the following address http://opentechcollaborative.cc/news/osbh01.html
We are currently getting some quotes to manufacture it in Australia and get the best possible price if the quantity is right. Please send us a message via the feedback tab if you are interested.
