I got all my parts in to make my tower kegerator. I have a Haier model bc 110 withthe freezer on top. I bent the freezer section down very carefully, now I have to drill or cut the top for my tower. I have to try the cornstarch and vodka trick, but if it doesn't work, anyone have any suggestions? I would hate it if I hit a line when drilling or attaching the tower with self tapping screws. Any help or advise would be greatly appreciated!
