So i've already purchased a 3 keg system.
I have a 7.0 cu chest freezer I will be building a collar for, I think I've seen enough plans to know what i'm doing there.
I'm planning on buying 3 Perlick Faucets 525SS and I will need 3 shanks.
My question is what size shanks do I need? Do I need a specific amount of extra beyond the size of my collar?
What else will I need?
