What size holes to drill?

[IBUPIMP]

I am getting ready to turn my old RCA refrigerator into a kegorator and was curious what size drill bits I will need for shank holes and also to run my gas line thru the side of the fridge??

7/8 for the shanks. not sure on the gas but maybe 3/8?

7/8" hole saw will do the trick. Overkill I know but I wanted something that looked a little nicer than just drilling a hole through the side. So, I used what’s called an Ice Box Shank Assembly. I also added Steel and Neoprene washers from Ace Hardware (inside and out) to finish it off.
