The last few weeks have been very productive at the steam shop! The guys have really made great progress in the tender; it’s been a pretty nasty job removing the years’ worth of epoxy. So far they estimate to be about 2/3 of the way done with the needle scale removal. New drain pipes were installed finally replacing the dated ones that were rusted and not holding water.
Test patch bolts have been threaded into the mud ring. The testing revealed a few minor modifications need to happen before the rest are installed. The outer throat sheet will also eventually need to be removed due to the cracks that were revealed on the interior side of the sheet. Those will be repaired before installment.
Brian has continued his needle scaling work on the cylinder covers. He has also begun to try and clean out the old insulation underneath the cover. Presently the covers are stuck in place and he is working to loosen them so they can be removed and all the insulation can be replaced.
The turret parts as well as the boiler check valves have been taken apart and readied to be hand lapped and cleaned.The steam dome cover has also been set aside. That won’t be placed on the engine until the final stages.The old brake shoes have also been removed and those will be replaced.
Using the diagram that was drawn last week, Marshal and Brian have constructed the new blower piece.
The oilers have been drained and the oil lines are being purged with air to clean them out. The guys will begin to identify the lines that need repairing and those that will need to be replaced. Joe was nice enough to showcase the old oil that they are glad to see removed.
The engine was moved a few feet in order to access an area behind the wheel for cleaning. Below is a short video!
Here is the latest turn table update from Project Manager, Tom Falicon-
All primary excavation has been completed and all 19 over length steel I-beam piles were felled like tall hardwood trees and then stacked neatly in the parking lot.
Concrete sub-footers were poured for both the ring wall and the center pivot. These sub-footers will provide a flat, solid work area to erect the concrete forms as well as provide a solid surface to secure them to in order for them to be able to handle to excessive force of poured concrete.
30,000 lbs of steel concrete forms for the entire project arrived from Charlotte early last week.
The storm water drainage system and piping for the center of the pit was installed and capped off just outside the poured sub-footer of the ring wall. The build of the re-bar cage for the center pivot started last week followed by the forming. The concrete pour for the center pivot will be completed soon.
The large steel plate that the turntable bearing attaches to had holes machined in it too large by the supplier so four reducer spacers were machined and welded them in place. The dead center of project has been identified and clearly marked. The plate will have to be painted before installation to help prevent future corrosion.
The underground water intrusion from the river and the creek has been challenging to deal with; water is constantly streaming into the pits. A gravel sump system has been built to help keep the pits relatively dry.
The project is moving along in an extremely timely manner! Great job by the crew working to get it done!
