Warre hive
vertical top bars need a pin to keep them secure.
I didn't have any nails that
size, so we made our own pins by cutting small sections of 14
gauge galvanized wire and hammering them into pilot holes.
Pay extra attention to the
space between the bars. It might help to mark all the holes before you
actually drill.
Dave --- The free ebook Beekeeping for All provides plans for building the hive. That website also includes plans for making the hive, in case you'd rather read the info on the web.
That said, we went ahead and bought a kit from beethinking.com ($195 unassembled with everything you need to make a high quality cedar hive with four boxes, plus top bars, floor, quilt, and roof.) Their instructions need a little work, but the craftsmanship of the hive they sent was top-notch.
If you've got time, I'd recommend making the hives yourself, but I got in a bind with taking so long to finish my book this winter and not leaving myself time to build bee hives before the garden season started....
