Here's a shot of the first stage nozzle ring installation. Once the compressor and CDC casing was landed, it allocated work for the front and aft end of the unit. As you can see, the manifolds are being worked in parallel with the turbine section.
Lessons learned: when installating new first stage nozzle there is the chance that the previous blocks are not of the right size to set it concentrically. We ended up machining .050" shims using the water jet cutter at our shop. Most utilities are not as fortunate to have such equipment at their fingertips. In that case, purchase larger horizontal nozzle blocks which can be easily machined down to the proper size.
