It’s been pretty steamy down at the steam shop with all the elevated temperatures and welding. We hope you’re staying cool!
Marshal and Brian have continued the steady work on the staybolt holes and Tim is back in the Tender needle scaling. Marshal has installed a temporary walking board, as they should begin to work on the top wrapper sheet this week.
The new piece of the throat sheet has finally been installed and it was quite the beast to get in! The fit was perfect.
Joe has been on the engine lathe fabricating the bushings for the washout plugs.
We’ve got a short update for this week! Most of the work has been centered on drilling the new staybolt holes. As of Tuesday they had drilled well over 1000 holes.
The new piece of the throat sheet was returned with the 8-degree bend needed and the holes for the flexible staybolts have been drilled.
Marshall has been working on readying the section where the new throat sheet piece will be placed.
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!
The steam shop guys have been busy this month and couldn’t be happier about the warmer/milder weather that has finally reached the Smokey Mountains.
The tender has been moved inside the shop and the cleaning has begun. Tim, one of our GSMR Operations crew members, has been recruited to help with Tender duties. He has been removing the old epoxy that has been inside the tender for several years along with prepping for the new marine grade epoxy that will be applied.
This past week Brian and Marshal have been pulling the studs off the firebox and wrapper sheet. The old rivets were shot out a few weeks ago! Stay tuned, there may be video footage of the rivet removal coming!
Joe has been working on the engine lathe making new rivet snaps. They are ready for heat treatment and then the next step of re-reviting the mud ring.
The remainder of the old firebox sheet has been removed and the mud ring inside was welded and grounded down.
Great news! The crack check was completed on the wrapper sheet and everything passed. There were a few minor repairs that the developer revealed when it was applied to the penetrant (the pink dye).
Things will be kicking up here in Bryson City as well! On Monday April 6 – crews officially broke ground for the instillation of the Turn Table! The heavy work will begin this coming Thursday when the pile driving begins. Stay tuned for photos and the latest information on that!
On this cold and rainy Friday we are so thankful for the nice and dry steam shop! It’s been a great few weeks with lots of cleaning and “de-rustification” happening! Noticeable changes are beginning to become evident with the look of 1702! Brian and Marshal have been doing a bit of welding work on the flue sheet. Making sure the holes are cleaned up and ready for the flues and fire tubes. We welcomed our new steam mechanic Joe to the team! This week he has been working on removing rust from the reverse gears. He is tediously taking small parts from the engine and working on them piece by piece. The side rods and the main rods have also been removed to prep for their detailed cleaning. Small parts are starting to shine again!
Say hello to Joe!
October has been an extremely busy month for GSMR operations. With daily double runs and special events every weekend the crew is working hard! Through the busyness the work continues on 1702. The interior sand blasting took about 3 weeks to complete and the engine has now been brought back inside the shop for more welding. Brian and Marshal have been working on welding the rivet and staybolt holes – over 1000. Once the welding is complete the exterior of the engine will be sandblasted to remove the rust. With this tedious task, steady does it! Here are few shots to enjoy!
