I've been on the hunt for 3 gal kegs (due mostly to space constraints in the fridge I want to use) as part of my mission to start kegging. But, we all know the cost of 3 gal corny's are insane. There is a place near me that sells 5 gallon kegs cheap. I can get get 5-7 of these for the price of one 3 gal. Has anyone taken 5 gal kegs, cut them, and welded them in to 3 gal units? Just wondering how that all turned out. Do they hold pressure? Cost to weld? Whatever.
