Here are the completed rivet heads on the fireman's side. I don't have a close-up shot of them, but in the riveting process, there is some excess metal smooshed around the head, like the "flash" you get with plastic models.  This will be chiseled out with an air chisel in a process called caulking.

In the meantime, the rear end tube sheet is now being fitted in place so that it can get riveted to the mud ring.  As the parts are installed, there will be welding to hold them together as a solid single unit.

A slightly different angle.  The three large holes near the floor will attach the siphons when they are installed.  Because of the siphons, there won't be a traditional crown sheet on the top of the firebox.  The siphon openings will circulate water over the top.
The colorful halo above the rusty steel is the inside roof of the boiler.  The halo indicates where the steam dome will be riveted.  This will likely be done before welding all the firebox in place.

It looks like the boiler work is progressing really well on the 3713.  Does the running gear require much work after the boiler is done?

As far as running gear, the side rods, eccentric crank and other parts, I would say not much more than cleaning off the years of paint and gunk.  I am not sure about the valve gear.  The pistons and rings were pulled out a long time ago. They will need cleaning and reinstallation.  
After the firebox is finished, the next stop would be in repairing the pony truck and the trailing truck.  I have heard the 4 wheel pony truck will cost about $18,000.  This money is readily available with a grant and cash in hand.  The trailing truck, with the steam powered booster will be more expensive.  I have heard $40,000 and up. This is because there are pistons in this too.  No real damage is known to have affected this, so the work should be a matter of cleaning. The trucks are being repaired so the drive wheels can be taken off.  There seems to be a good amount of material on the tires, but in the shipping of 3713 from Boston to Scranton in 1985, one of the axles was damaged, along with the bearings.  There are funds available for buying new steel for that axle.  
I don't believe there is a time-table on when she will run yet.  I am also not aware of what needs to be done beyond what I have mentioned.

What work is on tap for the coming months?  Will we see the firebox finished?  The trucks repaired?  I know that usually work will pick up the pace in the off season, and that many parts were outsourced for fabrication during the spring and summer, let's hope the progress continues.

I took these detail shots of the pony truck back in late October.  I did not think much of them at the time, but now I see the progress they were showing at the time.  The axles are out and are awaiting new wheels.  Apparently new roller bearings too.  

Here is the truck frame.  Newly painted and holding wood shims in place for now where the bearing boxes will go soon.  The bearings (bushings?) are now welded in place; ready to receive the boxes.

This is what the roller bearing box encasement looks like.  It is two cast steel pieces, top and bottom, that are bolted together.  The bolts are loosened on the top since there is nothing inside.

A wider view of the two parts together.  
From what I hear, the mechanical drawings for the top wrapper sheet of the firebox have been approved, and the steel is being crafted with the holes off site.  More to come.  I was hoping that the firebox would be completed last year, but things are still moving along.

The big topic of discussion on this locomotive the past month or so has been this item we see lying outside the back of the roundhouse.  It is the thermic siphon.  A device to keep water moving in the boiler and to maintain steaming capacity.  Not many locomotives have this since it is a rather late innovation.  There are 3 in 3713's firebox.  The old ones are too flimsy in some parts to be repaired, so replacements are being made.  

New panels of steel are being welded together.  They will also get staybolts installed, just like the firebox sheets will.  

This tube will be welded to the part shown in the previous photo.  This portion sucks "cooler" water from the lower parts of the boiler into the firebox region so it can be reheated.  It "spills" over the top of the firebox (crown sheet area) which keeps the water circulating.

These two portions are placed inside the firebox to make sure it all fits together.  They are like the piece shown in the second photo of this post.  
These pictures were taken on Jan 12, and a lot of progress has been made since.

Newer views of pieces taken Tuesday, March 12.

Remember this piece?  While not totally together, the pony truck is still waiting delivery of the new wheels from Altoona to go in the overall assembly.  But parts are coming together.

And this siphon... Sitting around today, but nearly ready to assemble in the firebox.  Notice the seam about halfway across. This seam and the same on the other two will be welded after the other parts are welded in the firebox, and the mudring is riveted.  

And this frame of the trailing truck.  Parts will be assembled to go under the firebox to hold the overall body up for riveting of the mudring.  Why is this?  Space that is blocked by the third set of drivers require that the drivers be dropped when riveting takes place. The trailing truck will balance out the weight of that huge boiler after the third axle and wheel set is removed.  When the boiler is sealed up, then work on the trailing truck and booster begins.

My camera was not handy, but today during the 10:15 locomotive shop tour, the trailing truck frame arrived back from where it was being repaired. It was a really neat sight as the 30-ton crane lifted the frame over the Baldwin 26 restoration spot. The wheel set and bearings will soon be added to the frame (without the steam booster for now). This will support the weight of the boiler and frame so riveting can take place in the lower forward area of the firebox.  
 
Meanwhile, a new display in the Visitor Center will highlight the next phase of fundraising to complete 3713's restoration.

Catching up.  At the time of RailFest 2013, this exhibit was unveiled to bring new emphasis on the restoration project, and to kick off the final funding push.

This exhibit has the authentic bell, reproduction signs saying "The Constitution" in the original black and white markings, and the marker lamps.  Since this debut, the whistle has been added to the display.  

You can take home some mementos of your visit, and hopefully a reminder of this restoration project.  A few designs have been made, so you can "collect them all" as the saying goes.

During the Superintendent's speech, L&WV Chapter president Vee Pauli stood with fundraising chair Carl Packer, who blew the whistle of 3713.  This was competing with the 425's whistle, of course.This photo was taken by Ceil Groblewski.

now for the March 2014 update.
This is the trailing truck frame for 3713.  It was straightened out off site, and returned to the shop in August. Bids were taken to sandblast the rust off, primer it and some other work, so it can then accept the axles, wheels and journals.  It needs to go under the frame and boiler so it could hold up that portion when the 3rd driver axle is taken off.  This axle removal will allow riveting to be done on the firebox.  Space in the shop is at at premium, so planning work space is as time consuming as planning what needs to be done.  The rust we see is from the straightening process, and the annealing.  Straightening the steel creates stress spots, and these need to be brought back to the normal temper of the steel.  Annealing will "de-stress" the metal. The rust is not a big deal, but can't stay forever.  This sandblasting, priming and painting will be done off site.

For the modelers in the group...

A limited edition O gauge and HO gauge boxcar introducing 3713 as America's Locomotive is now available.  The O gauge is made by RGS, and the HO is Life-Like Proto 1000.

B&M 3713 looks kind of lonely on track 4.  The restoration crew were waiting for approval of a proposed welding technique on the engineer's side of the boiler to be approved by the FRA.  This has ground the work to a halt.  I believe the procedure has been finally approved, and the project can move forward.  Meanwhile, the fundraising continues.

3713 was brought to a new track on December 17.  "All the way" over to track 5.  While it is only a one-stall move, it brings her more into the center of the action of the locomotive shop.  This is alongside the open space where most tours walk, so she is less hidden than she was in the past.  

She also looks a lot bigger than we have become accustomed to seeing her.

 
This view shows her proximity to Baldwin 26.  As 26 gets moved out, 3713 might get to take this center space in the shop.
 

 
The more practical reason behind 3713's move is that GP9 514 needs the walkway access that track 4 allows.  Her long hood will be removed so they can reach all of her innards, and complete a lot of the work that was not finished, or had crept in since last winter's re-wiring and the year before's other repairs.  This should make for a busy winter in the shop.
 
The large machines wrapped in cellophane are the repaired Generator and auxiliary generator which will be installed in F3 number 663 sometime around March.

www.project3713.com has been completely re-done for 2015.  It debuted today.  It is more immediate on the fundraising end, but will also contain progress reports when they come along.  This is going to be a big year for 3713.

A new item at Steamtown's Eastern National bookstore.  A design of coffee mug with Boston & Maine 3713.  This is a different design from what you would find at other train shops that sell coffee mugs.  It is a Steamtown exclusive.  Here is the other side.
 

 
They are available when you visit Steamtown, or you can order it over the phone at (570) 340-5213.
 
By the way, there are about 2 dozen O gauge boxcars left, and the HO cars are nearly sold out.  Don't miss out!
