April-May 2017

This spring work continued on the steps and end platforms as well as insulating the car and tightening and securing the truss rods.

 This photo shows Craig drilling through the metal bracket for the stairs into the stringer in preparation for securing the steps to the car with bolts.











In the photo on the left two bolts have fastened one side of the steps to the car bracket.  The stairs were centered and leveled prior to drilling the holes.










The other side of the steps was bolted to the end sill of the platform.












The steps on the other side of the car are shown here with both sides bolted on.
















These bolts are temporary, but this photo shows that the nuts are counter sunk.  Proper length bolts are being obtained.













Here Craig and Debbie are getting ready to fasten down the oak decking on the platforms.












First holes were drilled and countersunk through the oak boards.












Then the screws were inserted with an impact driver after being coated with beeswax.  Having put in some of these myself I can attest to the fact that they will not come loose.










This is a photo of our car when it was in service as a kitchen/diner.  John noted that the end of the platform end sill was narrowed with some of the wood cut away underneath.  (Click on image to enlarge.)








The decision was made to remodel the ends of the sills to conform with the original appearance, and in the photo Craig is starting to grind away.











He used an oscillating tool as well and it is taking shape nicely.












Quite a bit of time and effort was spent on preparation for insulation of the car.  One of the chores was to replace the spacer blocks under the windows that were removed during disassembly.  One of the blocks can be seen in this photo next to the metal square on the saw table and one can see that the shape is unusual.  Of course we were short a couple of these when it came time to replace them so we had to make new ones using an old one as a pattern.





The photo to the left shows Ron replacing the blocks under the windows and nailing them in place.
















Work also continued on cleaning out the floor spaces and sealing around the framing.  Ron is wielding the vacuum in this photo.











This photo shows strips of plastic around the framing in preparation for spraying in the foam.











The bolts and tie rods in the framing were tightened prior to insulating.  Here Ron and Bill K. are working on the bolts between the inner sills.  There are pipe spacers between the sills to keep them apart.














In this photo Bill is nicking the threads on the vertical tie rods so the nuts will not move.












The insulating company came on two consecutive days during the week and sprayed the insulation on the floor and ceiling.  The windows were covered with plastic prior to spraying.  In this photo a worker is starting at the east end of the car spraying the floor.













Here is a closeup of the spray gun in action.

















This photo shows the car after completion of the spraying.

















There was some overspray and here Bill K. is cleaning off the rafters.  The sections where the compartment dividers will go were not sprayed as can be seen in the upper right corner of this photo.








Another job that was started this month was to caulk the roof, nail holes, grooves, etc.  Here Don and Bill L. are assembling the platform along the north side of the car for access to the roof.








Then the scaffolding gets assembled on the platform.

















They are starting to work on the roof at the east end.

















Don is filling nail holes from the scaffold in the photo on the right.  But sometimes you just have to get on top of your work, as on the left.









Joe finished polishing the welds on the queen posts.  They are looking good.











Joe also welded a flat piece of steel onto the post of the jack for the trailer as shown here.
















At the last work session the trailers were loaded to move some things down to the RR as the summer work sessions are starting.  Here the crew is loading posts for the corrals, I believe.










The threading machine is on Craig's gooseneck to go back as well.











So we will be taking a break for a few weeks in COS during the work sessions in Chama and Antonito.   We resume in mid-June.

Thanks again to John and Tom for photos.

March 2017

March saw completion of the underside sheathing, installation of the longitudinal truss rods, progress in sealing the floor cavities and fitting the steps, and more work on the trailer.

Bill K. and Don are at it again under the car.  They are very close to finishing installing the sheathing underneath.


























On the left, above, they are down to the last board.  On the right, above, Don is measuring twice for a perfect fit.

 In goes the last board.  Great job, guys.













Here is the end result.  We are looking in the opposite direction from the previous photos.















Bill L.started sealing the floor cavities in preparation for insulation to help keep out the cold and noise.  The first task was to clean out the dirt and sawdust with the vacuum.









Then strips were cut from the roll of plastic sheeting that has adhesive on one side.











On cool days the strips were laid out in the sun to soften the adhesive.

















The strips were then put into the cavities against the framing and the plastic that had been installed from underneath.











This is a section that has been completed.












This photo shows the steel plates that will fasten the steps to the body of the car.  The one on the left is an original one that was left on the car.  The other three were missing, so Joe fabricated the new ones on the right using the original one as a pattern.








In this photo Joe has positioned a plate for welding to the end sill steel and has it held in place with magnets.  (Click on the photo to enlarge.)






In this photo he is welding along the inside edge.










A view from the end of the car of the plate welded to the sill.











This is a view from below and behind the plate showing the second weld along the edge.  The side of the step assembly will be bolted to this plate.










This photo shows the flat surface of the plate after grinding the weld and polishing.  It is difficult to tell where the weld is located.















This photo shows the steps on the other side of the car positioned and leveled, and held in place with clamps.  The steel plate is on our left.  The right side of the steps will be bolted to the platform end sill.





John did some snugging up of the platform truss rods.












These are the under-the-car longitudinal truss rods to be.  They have been cut to length and Joe will take them to his shop to have eyes welded on one end and threads cut on the other.













The rods are back, being unloaded from Joe's truck.  Seems like a lot of manpower there, but they ARE heavy.











Russ Hanscomb made these eyes and Joe has welded them to the ends of the rods.  He has also ground down the welds so everything is smooth.










This photo shows the other ends of the rods that have been threaded.












 The next step is to bend the rods at the points where they pass under the queen posts.  Don and John are measuring and marking the spot while Craig is looking on.











We used a hydraulic "bender" that pushes the rod up between two posts to produce a bend.  Ron, Joe, John, and Don are getting set up to bend.











A level was clamped to the end of the rod at the eye to insure that the bend was at right angles to the pin in the eye.










This photo shows the rod after bending.  The device is essentially a hydraulic jack that pushes up on the rod to bend it.











This photo shows one rod in place.  The far end is the eye which is fastened to the bracket on the bolster and the near end is threaded to take a turnbuckle for tensioning.  The queen post is at the bend and will apply upward pressure to the needle beam as the tension increases on the truss.







Now both halves of the truss are in place, and John is threading the turnbuckle on to the rods while Joe is helping line them up.











This photo is looking in the other direction showing the other end of the truss after the turnbuckle has been snugged up.










This photo shows a detail of the end of the rod in the bracket with pin and cotter key in place.  The bolster is in the background.











This photo shows the entire truss in place under the car.  Because of its geometry it can support the center of the car between the trucks.















This is a detail of a queen post with the truss through it.  Joe has polished the weld on the end of the post.
















Joe also did more work on the trailer this month, building ramps for loading vehicles or equipment.  In this photo he is measuring prior to doing the work in his shop.















This photo shows the completed ramps.  The bottom end grabs on to a pipe across the back of the trailer.











The ramps can be folded up while travelling.











Thanks to John Engs for help with the photos.
