We got all the rest of the chiller pipe laid. This is the piping which will be buried in the concrete, that will carry the glycol, at 20 degrees or so, chill the concrete slab down far enough for us to make ice.
Once again, a lot of hard working volunteers helped make it happen. Dave DeFehr, Matt, Jordan, and Tom from Daveste Vineyards, Pat McKee, Peter and Spencer Strickland, and Steve McKee, along with the crew from Everything Ice, the ice slab contractor.
So we laid all the pipe. In order to do this, we had to set up a jig to put the spools of tubing on. They came wrapped and the manufacturer used enough black tape to secure the pipe on the spool, that it probably would have withstood a tornado. When we unrolled this, we were not able to remove much of the tape as we were pulling it off the spool, and setting it in the pipe chairs (these “chairs” were metal brackets that hold the pipe apart uniformly, and keep it exactly the distance we need from the top of the concrete.)
Sooooooooo………. Once we laid out all the pipe (did I mention we had to lay 7 miles of pipe!!?), and tied it down…………. You guessed it. We had to go back over that 7 miles of pipe and peel any and all remnants of tape off. Picture this, you have black pipe, black tape, it is suspended over the vapor barrier by the chairs, and guess what color the vapor barrier is. Yup, black. And we don’t have real lighting yet, we only have halogen lights, so the lighting in the place is very dim.
I do not exaggerate when I tell you we used about 30 man hours taking the tape up. We first went up and down the pipes, pulling everything we could see. But we noted that we seemed to be missing a lot. so then we had to walk side to side, combing through it with our eyes to spot where there were bits of tape, and we found a lot. And then we wound up going side to side in the opposite direction, because we realized even then, that it needed another pass, with different lighting, and yes, we found lots more tape. We probably filled three 5-gallon buckets with remnants of tape!
Then we started to put down the wire mesh that goes on top of the chiller pipes. The entire surface gets the wire mesh, so that the pipes will be exceptionally uniform, in both their distance from other pipes, and their distance from the top surface of the concrete. all of this in the name of getting even chilling, uniform ice conditions and good curling ice.
You will see the pictures here that show you all of what I am referring to.
