Stopped known leak on GNB spool (again!) at Y-mid
Wanting to eliminate CP3 as the source of the leak that appeared on 12/27/2015, I applied still more Vacseal to the area of the previously stopped leak which had been stopped months ago (see various aLOG entries) the difference is that this time a stayed away from the "cut/gouge" area that I had attributed as being the site of the leak but, instead, applied it only in the area where the spool roll seam weld interfaced with the stiffening ring stitch weld (also in the gap beneath the stiffener) -> WAHLAH!
