Steam Department Update 09-08-2012 Posted by Nigel Bennett

Comments (2) Steam Department Update 09-08-2012Another week of steady if unspectacular progress in anticipation of the inspection next weekend. On 1630: · It was good to see that the welding contractor had made a start on attaching the safe ends to the super heater flues during the week. The process is not yet complete as each is first welded with the high penetration 6010 welding rod and will subsequently be surfaced with the harder 7018 rod.
For my peace of mind we test fitted the two that now have the ends attached into the boiler. The sensitivity with this is that the finished flue is a little over 17 feet long. Most will have sections welded to each end of the original tube and these are not just butted onto the end but tapered and partially inserted into the original tube. The objective is that the finished flue must fit between the tube sheets with a 1/4 inch projection at each end. Less is a disaster, meaning that the flue has to be re-welded, but excess means work as it will have to be ground off. So a lot of measuring and calculation went into determining how long each of the three pieces should be to give the right final length for each flue. Much to my relief the first two are good and accurate to maybe 3/16th inch. On this basis we re-checked all the remaining ones so all is set for the welder to move forward. · This also allowed us to evolve a safe and effective means of "loading" the flues into the boiler. This is not trivial as they are both heavy and 17 feet long. The fork lift proves ideal for this as we can lift the flue to the required height and then slide it from the forks to the tube sheet. · Work was started on bending and fitting the new pipe work along the side of the boiler. The first one being replaced feeds the cylinder lubricators. Good progress was made on this and it was in part a learning exercise so that subsequent work should move faster. Although small diameter overall, this is heavy duty (schedule 80) pipe as it carries steam pressure. So it is by no means easy to bend. The conclusion so far is that it can be bent with reasonable accuracy by hand with no tendency to collapse if you use the acetylene torch to heat the exact area you want to bend to red heat. Here you can see behind Ed where the pipe had to be formed to fit around the riveted seam of the boiler barrel. · The cleaning and thread clearing on the super heater bolts was completed. We now have the required 27 clean, lubricated and ready for immediate use when we come to fit the elements, hopefully in the Spring. · Mike, Ralph and others continued forming the test patch for the firebox. This was heated and formed to fit into the sloping face of the front tube sheet, which is the most tricky part of the bending, where the patch is not a simple curve but must be bent in three dimensions. Based upon this work was started on the second test piece that will be used to prove the process of forming before the actual boiler sheet is done. · Hopefully some more progress was made after I left early to attend the Board meeting. That was an interesting session that left me with no doubt on the importance to the museum of getting 1630 into service in 2013 !!. In other areas: · Machining of the 4th axle box for 428 was progressed. · Rick removed the rust form the compressor housing and primed it. Hopefully we can paint this during the week and avoid further deterioration ahead of the winter. · Bob milled the engine mounts for the new motor that the track department are fitting to the tamper.

CGW X 38 Update - September 5, 2012 Posted by Robert Kutella

Comments (3) CGW X 38 Update - September 5, 2012As we set to work in the morning it was raining so we moved into the wood shop. Dave Rogan, Rich Witt, and I manufactured about 50 feet of special profile molding (two different shapes) to act as stop jambs for the window and door openings. The rain stopped so everyone shifted gears and went to our 'outdoors' shop space. Buzz Morrisette was fastest on duty and he continues to cut out damaged flooring and to replace the heavy boards. Mr. Hans Bolt was visiting IRM from Switzerland and we showed him the plow work in progress. Dave Rogan is explaining the mechanism for moving the plow wings. Victor Humphreys set up ladders to work in tight places once we opened the plow wing. He wirebrushed all the areas needlechipped of many layers of old paint, and then set about applying primer. It is pretty easy to see large flat areas of the side that are cleaned and ready for paint. But there are a lot of odd details still needing attention. Dave steadies the ladder while Victor gets to the upper rear edge of the wing. There is always some task ready for attention. When Victor did not need a ground man for the high painting, Dave Rogan set up a needle chipper and began to attack the steps under the rear door. Dave also did some work chipping the cast steel door threshholds during 'intermissions'. Here is your quiz for the day. The rear truck has casting marks indicating it was originally for the New York Central. Interesting, but not unheard of for rail equipment to have had their trucks swapped for any number of reasons or maintenance. But look at this image. To the right of the bolster pocket there is a raised part of the casting, with a hole in it, and a slot behind that hole with a sheet metal retainer of some sort. There is one on each side of the bolster pocket. Does anyone have an idea what their purpose was?? We considered that these are freight car trucks. Parts of the NYC ran from third rail but no reason to attach any kind of device to pick up current for a freight car, and unlikely there could have been any need for an inductance box or other device to be hung there, to trigger signal indications.

Comment (1) CGW X 38 Update - September 1-3, 2012This will be a relatively short update. We did not have a lot of volunteers, and many probably chose to spend the unofficial end of summer, Labor Day Weekend, with family or other pursuits. But we did get a lot done. This is the rear wall, now nearly done. Saturday we did some blacksmith work and straightened the metal above the rear window. It had bowed inward about a half inch and there were sledgehammers swinging and some new words invented. With the wall straight, we fabricated remaining window framing, primed it, and installed it, as seen here. You can also see some of the bodywork and filler that has been applied to smooth out weld areas, where the missing metal panel was welded in below the window. On the north side the goal is to have some finish paint applied very soon. But needlechipping remained to be done in some fairly inaccessible areas. Maybe that is why it was saved until last. Look up under the small roof overhang behind the plow wing, half is cleaned up. By days end, all had been chipped as well as the short notch wall behind the plow. Of course that meant we got to charge up the air system and move the wing out, and then back in. Obviously a railfan effort of fun, but we 'needed' to do it. On the front nose of the plow is a massive anchor casting and that is used to mount a front coupler when needed for ferry moves. There really is no springing or draft gear in the traditional sense, merely a very stout pin to hold the coupler in place. What you see could interfere with good snow removal and the air pipe and hangers often got damaged or bent in severe situations. So it was made largely removable for winter operations. There is also a train air pipe down to the coupler mounts, and when the coupler was removed, that pipe has a universal joint and the drop leg is swung back and over the plow roof, to rest upon it, in front of the cab cupola. In the background, note the passenger department roof repairs underway on DM&IR 84. Surely you modelers will want to include this detail on your masterpiece. Walthers made a model of the Russell Plow in HO scale and while out of stock, they can be found on E bay. This detail is not included on the model. A little kitbashing and adding details and you will have a very credible model of the real thing, only found at IRM in Union IL. I will digress strictly from the snow plow report, here, to show a rare visitor to Barn 4. The Nebraska Zephyr is receiving a detailed inspection and some repairs in preparation for the upcoming excursion trip. And in the Freight Car Department we completed a two and one half week blitz to repaint our Borden's Milk Car, BFIX 520. We sanded, primed, and applied two coats of finish enamel to the top half of the car, as well a some washing and cleaning, and a repaint of the black handrails and grab irons.
