When I do my next inspection, I'll need to pull the frames with honey out and replace them with new foundation. I ordered a 5 pound box of 100% beeswax foundation to replace the plastic foundation with and it arrived this morning. The only frames i have are the grooved type. The sales catalog recommends using a wedge type frame for the beeswax foundation. I have inserted a couple of pieces of the beeswax foundation into two empty frames and it fits well enough, although much looser than the plastic foundation does. Should I wedge a small piece of wood or something into the grooves to help hold the beeswax foundation in the frames before placing them in the hive?
