PCAL Periscope Flat Head Bolts

Jim and I went in today and tried our hand at some of the bolts on the periscope. We had high hopes since the 3IFO periscope looked good and the bolts freed easily. Unfortunately, these bolts had their hexes almost stripped on many, if not most, of the bolts (see attachments). With some breaker bars we managed to get out all of the ones we need for the vibration absorbers, and then we started on some for the baffle panel brackets with Betsy guiding us to the correct ones. Overall it was a good success with more work tomorrow. And we only bent 3 wrenches in the process!

Also, I didn't get any pictures of where we left off, check back tomorrow.
