Today we finished installing the last 3 of the turntable ring rails. The first 2 were the 20+ foot long ones and they weren't very hard to install. The last one was around 8 feet long and had to be cut from a spare rail and then heated in order to curve it to fit the space available.
Many volunteers were hand to help us push the turntable bridge itself around the pit to test it. It worked well, but will still need some slight adjustments.
