Gradually getting my gear together to do a full 5 gallon boil of extract in a DIY keggle. Keg in hand and top cut. Now what? I want to add a spigot but not sure how high or what I need to do for the inside pickup. I plan to go weldless to keep it DIY. Do I need a thermometer or sight gage? I may do what many others do and progress to all grain and willing to build the keggle for future expansion. If it matters, I will be using a DIY immersion coil chiller. Do I need to be consider potential contact interference between the coils and any piping added to the inside of the keggle? Any advice and pics will be greatly appreciated. Thanks!
