Any suggestions on how to add Lang supers to this log gum? I guess I could chainsaw the top level and add a board, but there is a lot of comb, honey and maybe the queen up there. Or add the board with some leveling walls to the slanted cut? Or us a super as shown as a transition? Use some flexible vent tubing up to a board? The bees are gentle as lambs. It came with a sweatshirt covering the big opening.
