I stole/hijacked some brilliant plans from topbarbees.wordpress.com. They were in Google Sketchup, but I translated them into pdf on 8.5 x 11 paper for easy emailing and printing.
I've been tweaking the plans trying to work out the ventilation and the bottom board. I've added a follower board that doubles as a bee escape, etc. Anyway, I would be happy to share them and would love some experienced folks to correct any problems. So if you would like a copy please email me at [email protected]
