Here's a thread that I posted a while back. It has a link to some pictures of the system.
I need to update the pictures. I have made some changes over the years.
edit: Added later pictures with modifications to my rims panel for electric kettles and misc. systems shots.
Also a direct link to the pictures below.
When I'm not brewing, the kettles and MLT tear down and get stored on hooks from the ceiling so I can use the counter space for other uses.
I have found that hose barb fittings and hose clamps make a cheap, reliable quick connect system with my system. Even the 1/2" copper line works well with 5/8" ID reinforced vinyl hose and hose clamps.
