The shelving is just some heavy duty adjustable chrome wire shelving I ordered from www.theshelvingstore.com. 4 x 44" posts, 2 x 34" posts, 6 x 4 inch swivel casters, and 3 x 24" square shelves. Came to about $225 after shipping and it comes with more clips than you'll probably ever need. The shelving is rated to 800 lbs evenly distributed so it doesn't even bow under the weight of an almost full 10 gallon rubbermaid mash tun.
Mash tun is your standard home depot cooler with a 1/2" stainless ball valve conversion kit. For lautering I made a CPVC manifold and connected it with a 1/2" threaded CPVC fitting:
The kettles I picked up from Spike Brewing, they have a couple small dents here and there but nothing game breaking. They get the job done for a great price. Both kettles have two horizontal welded couplers. HLT has ball vave on one, T fitting with 6" probe thermometer and sight glass on the other. The BK has ball valve and just an elbow fitting with a sight glass. I picked up all the fittings, thermometer, and sight glass equipment from brew hardware. Once I get a pump, I'll use it to pump from the HLT on the bottom to the mash tun and I won't have to do any lifting other than to clean the mash tun when I'm done.
Burners are just your average banjo burner and I've got a separate propane tank for each, although you can limp by with just one if you really need to.
