I recently purchased the ge 7cu ft freezer from SAMs club to hold my 4 corny kegs and draft tower based on a couple of projects I have seen here and elsewhere online. It's done with a four handle tower and two five pound co2 tanks on the hump but I can not get all four of the old cornies to fit at all. Any ideas? I know it's supposed to be tight but the fourth keg will go no more than halfway down no matter how I turn them. Was thinking of trying to shave off some of the rubber coating at the bottom of the kegs but I can't seem to find an easy way of doing that. Anyone have similar issues?
