I made it a point to try every new idea I heard about.
So yes, I used some vertical & some angled skewers, which worked ok, I guess. the bees didnt really want to attach to them, but eventually did. (not 100% failure, probably 100% success with a little edge prompting, & time.)
I also cut strips on my table saw , Similar to Rich's paint stir sticks, but not as wide, for the top, & going forward, I will be adding a little filler strip in the bottom groove to try to reduce hidy-holes for shb, or other varments. I just shoot about 3 staples in from the side to make sure the top strip doesnt fall out. friction holds the bottom strip.
I am sure I am doing something wrong with my waxed foundation frames, the wax sags out in the summer heat if the bees dont draw them quick enough. especially the deep frames, which I swear I will get rid of this year. ( fishing line on both sides of the wax seems to hold it in OK)
All my frames are Dadants "wedge type" economy, made so they would hold foundation, but very versatile, & cheap.
I will attempt more cut combs this year, so I will try more " unsupported" foundationless this year. ( this may change as the season cranks up)
if I had 10,000 hives, I would have to do something less labor intensive, but I have closer 10 hives, so all this is doable for me.
Good Luck !!! CE
