SLC ACB "new" holes plugged
Jim and I installed vented hardware into the holes we tapped for the ACB work. So no more dropping chips during strong HEPI motion. We did not bore-scope the holes.

At Mike's request, Bubba and I scopped the holes. Here is the url: https://ligoimages.mit.edu/?r=18431 to the 5 minute 32 mByte video file for your review.
We saw some things in the threads of some of the holes and some bits up above the threads so it is conceivable that there may have been other chips that were shaken out on March 2. It did not appear that any of the remaining bits were loose as we did not dislodge any with the probe although we did not really try to do that. Certainly any bits now remaining will be trapped by the installation of the vented bolts.
