Good luck, you won't believe how much fun it is to have an OB hive around. I have been building them all summer. They are not difficult, just don't expect the first one to be perfect and you will be fine. I have been using one all summer as well and I have not had trouble with the glass in the grove. I use plexi-glass instead of real glass and I am also in mine about once every two weeks or so. Maybe they are not getting enough time to really propolis it in. I could see where it could be trouble. But I have not had significant trouble getting the glass to slide out.
Would be worth looking into the pieces that Micheal describes though, I could see that might work really well also.
Frantz, Are you building them to sell, i was really looking for one next year if they aare reasonibly nice., even if i had one to look at in front of me i can copy stuff down pretty good but im not muh of a screen learner What do you do in it every 2 weeks? Do you have the correct bee space that Michael Bush suggest, so they dont burr comb it up? How many frames is it?
Thanks, i might be looking to buy one it is the size i want and the right price, but i imagine once you got the template you could make them about any size.
