Thanks Jon, DR and Drumgerry.
I'm a very careful handler of bees, Jon. The problem is usually when putting the boxes together - particularly the poly ones with their wider side walls.

Some people put on the super at an angle to the brood box and then rotate it around slowly to sit properly on the box below.
personally, I find that will always catch a few bees.
I prefer to line up the super with the brood box at the front edge and drop it back very slowly while using the smoker to clear the brood box edges of bees.
DR's wedges would help here as a heavy super can be tricky enough to drop down slowly holding it with one arm.
