After 6 years of extract I decided to switch to all-grain, and figured it was time to go big or go home. So after lots of research, and 3 months of fabrication in the evenings and weekends, its finally done, and I brewed by first batch on it today (a Sierra Nevada Pale Ale clone). First day's efficiency wasn't great, 63%, but its all improvement from here I hope.
About the system; 3 converted Sanke kegs, 2 banjo burners, 1 March pump, 10 ball valves, 25' x 1/2" HERMS coil, hard plumed with 1/2" OD stainless lines. The frame is 1-1/2" square x 1/8" steel tube, powder coated with 1000F smoker paint (and it still blistered by the burner!).
I'll post more pics once I remember how to make an image folder public in Google Docs.
