That wasn't so bad after all. After mashing for 60 min, the temp of the mash was 151F. Cracked open the valve, and nothing came out. Blew in the hose a couple of times, and got the flow started, recirculated to get as clear as possible, drained, added sparge water and repeated with no stuck sparge. I collected 7 gal wort with a pre-boil gravity of 1.043 (Beer Smith said 7 gal at 1.041), so I got 75.8% mash efficiency instead of the 72% BeerSmith estimated. I think I done good for my first time there. I got it chilled as much as I could with my chiller, and it is in the chest freezer now cooling down to pitching temp.
I don't know why I was so freaked out about doing this. It wasn't that difficult, and it was an enjoyable morning outside with my dog before it got too hot. I can't wait to do it again. Now for another cup of coffee before I make some lunch and have a well earned beer or two.
