Hey, building my kegerator. The friggin cornstarch thing isn't working for me. I've read enough about these fridges where it seems like I can just trust that if I drill a 2.5" in the center of the plastic top straight down I'll be fine. The freon line is like 7-8" from the back? Um, do I have to go out an buy more cornstarch and some cheap alcohol or can I just do this... I was thinking maybe doing a 2" hole rather than 2.5"... There will only be 2 lines running down there wouldn't it make sense to keep the hole as small as possible anyways? Advice please.
