BSCISI#2 Horiz GS13's Installed on Stage 2
	(Corey, Greg)

	Yesteray it was decided we would go ahead and install the (6) GS13's which are NOT vacuum-ready (basically they can only be used for testing and then need to be pulled out and exchanged with GS13 Pods that pass a leak check). 

This afternoon we spent roughly a half day installing (3) of the horizontal GS13's.  I had not done this before, so I had to remember how we did it on Assembly#1 and also had to deal with an out of date assembly procedure (and a drawing which had a few errors).  Now I don't remember Tooling being used for installation last time, so we went ahead and manhandled these horizontals in.  It wasn't too bad, as I moved them in to place and Greg would secure them on to the assembly. Here are notes for each GS13: Corner #1 Horiz S/N 37 (not vacuum-ready, must be replaced!), and we used (2) of the thick Mizumi washers for shimming the Stabilizer Plate Corner #2 Horiz S/N 14(not vacuum-ready, must be replaced!), and we used (1) thick  & (1) thin Mizumi washer for shimming the Stabilizer Plate Corner #3 Horiz S/N 27(not vacuum-ready, must be replaced!), and we used (2) of the thick Mizumi washers for shimming the Stabilizer Plate Note:  Didn't  get to torque the 5/16 bolt on each assembly which is on the flange base and closest to the center of the ISI (the nearby actuator was in the way for our socket, and we only had one type of 1/4" socket to work with.  Need to figure out a way to torque these down.
