I,am looking to build a boka and have yet to get a keg but I think I have one lined up, this afternoon I am off to buy some pipe from a plumber. He has offered me some 4inch and a piece of 2 inch i think about 1400mm long .
The question is what would be the best size to use I know there are plenty of 2 inch bokas and would 4 inch just be over the top to hard, not fesable etc.
Thanks 1pot
