Pumping and Stout

As my quest towards overdoing my brewing hobby continues I've begun slowly upgrading to a RIMS (Recirculating Infusion Mash System) brewing system. Basically, that means I am installing a pump that recirculates the mash, adding to efficiency and clarity of the wort. I mounted a "pumphouse" on the back of the brewery with valves and a recirculation loop to allow me to draw wort from the mash tun and pump it back over the top of the system. I'm also considering change the mash tun to a 15gal one I found at Wally World for $20. It would allow for more wort volume...

The nice thing is that most of these things are freebies (pump, valves). So the upgrade is mostly labor and design. I can't find my digital camera, which is why there are still no pics!

Why am I working on upgrades? I've volunteered to participate in the BBG Bourbon barrel stout project, and the grain bill is pretty tall!
