I have begun gathering parts for my keezer build so far I just bought an 8.7cu ft. chest freezer from lowes and have purchased the johnson controls tempature control. I am going to build my collar next and would like to drill all the holes for shanks and stain and urethane the the collar but I am not ready to buy all the taps. I have seen some plugs in place of taps, any idea where I can pick some up?
