Been preparing my frames for what I hope will be a good season. My general practice has been to slip the sheet of foundation in the slot of the top bar of the frame and to electrically heat the support wires to hold the sheet in place. I've tried on several occasions to stick the sheet to the top bar with bees wax but not with much success. The result is that, sometimes, because it is unattached, the weight of the bees pulls the sheet out of the slot before they can attach it to the bar with newly built comb. Then the foundation folds over and makes a messs of the new construction. Can any of you experienced foundation-fixers give me your "secret" method for preventing this problem? Do you wax your foundation to the top bar and if so, how?
