Nice rig. I have built myself a draught box. Unfortunately it sometimes gives me grief with foaming, so I don't have all the answers, but here are some things I have learnt: 1/ pass beer through the lines before placing the coils in iced water, to avoid ice crystals forming inside the coil and causing nucleation points for the CO2 break out, 2/ you need to put the coils in an ice bath of ice and water to effectively cool the beer; ice alone will not have enough contact with the coils to cool effectively, 3/ minimise the length of beer line exposed to ambient temps as this will cause CO2 to break out. I find I get more foaming when the beer is consumed more slowly (more time for the CO2 to break out in the lines). When the beer is consumed quickly I have no issues with foaming or the beer not being cold enough. I typically have the kegs pre-chileld which obviously helps with coldness, but I am tempted next time to have ambient kegs and see if that improves foaming: it may seem a little counter-intuitive, but at least worth a try.
