I plan on building a top bar give soon. My only real quandary remains the top bar comb attachment system. There seems to be a gazillion ways to do it. My biggest concern is in using any bees wax product. First the potential for introducing disease. Second relying on bees wax as a structural attachement can fail in hot weather. So I'm looking for other ideas that are favored. Popcycle sticks in a sawn slot with carpenters glue seems easy and strong.
