Monday, November 29. 2010CNW 6847 progress, November 27, 2010Earlier in the week on Monday morning, Dave Diamond drove the wheelset that was removed from 6847 along with the new motor to a shop just outside of Chicago. They pressed off the wheels and gear, machined the bearing surfaces on the axle, and pressed the gear and wheels back onto the axle and reassembled the combo with new support bearings. Initially there was over .350" of lateral between the old motor and wheels, which is out of tolerance. After the machining and pressing the gear into the correct place and after reassembly with the new motor and bearings, the lateral was .079" where it should be. Dave Diamond helped us out again and picked up the combo on Wednesday morning and unloaded it in the steam shop under the overhead crane.  Rebuilt combo. Saturday morning, Roger Broms, Dan Currens and myself arrived and started to do some other prep work including replacing a broken bolt on the nose pack, and then compressing it to be reinstalled once the motor is back in the truck. The nose pack is basically a rubber pad sandwiched between two thick bars of steel, which supports the nose end of the motor against the truck frame. We also mounted the blower duct and roller bearing boxes and then moved the motor to the drop table.  6847 positioned over the drop table. The Steam Department volunteers helped us out again as well by getting the drop table ready to go and helping get some tools and supplies, as well as operating the crane to stage the combo on the drop table for the installation. The 8537 was used to push the 6847 onto the drop table, centering the #5 axle over the table. The position of the pedestals was marked on the table, and then the table was lowered a bit and moved to the west side of the pit. The centerline for the wheels were marked and then the combo was placed with the nose of the motor blocked up.  Setting the combo on the table. The table was lowered and moved back to the east side of the pit under the loco, and raised back up stopping occasionally to check clearances and to line up the roller boxes with the pedestals. We had to push the firemans side wheel over just a bit with a bottle jack to get it to line up exactly in the pedestals, then raised up some more. Eventually the motor nose supports lined up with those on the truck frame and we slid in the support pack and pinned it in, lowered a bit to remove the blocking under the motor, and then continued to raise the table until the springs seated properly over the roller boxes. The table was clamped back into place and the loco was moved back into the shop.  Checking the alignment as the table is raised. We then put the pedestal cross bars back on, remounted the brake shoes and shock absorbers, released the bolts holding tension on the rubber nose pack, hooked up the traction motor leads and inspected a few other items. After all that, we moved the loco back outside and Jim West helped move the 428 and Shay back into the steam shop. There is a gallery setup with some random photos during the process of changing the combo, http://www.irm.org/gallery/diesel-november2010, they are mostly in order from the prep work, to removing the wheelset and old motor, to installing the new motor and wheelset. Thanks to everyone that helped during the entire process. Next year when the weather is warmer, we'll test everything out operationally and CNW 6847 will be back in service again. Monday, November 29. 2010Wood Shop Update - November 28, 2010
We seem to be falling into a winter work pattern, with Saturday by far the busiest day in the shop areas inside Barn 4, then Wednesday, and Sunday holding onto third place. So take note that there is more space and less competition for machine time and bench space on the latter two days, if you want to work on your favorite project, or to just show up to watch and help the others.
 The Baggage Door Jeff Brady is working to glaze the top three openings on a new baggage door for Michigan Electric 28. This is a good cold weather project, when the barn space is really too cold to accomplish a lot. Ray Schmid is in the background painting the retainer beading for the glass.  The Plane Truth Bill Moran was on hand and we decided to start the process of planing stock for a new roof on the Los Angeles coach using the planer to reduce the thickness of the new lumber (sawn on Saturday), to the planned 7/16". Here he is removing one of those 16 foot long strips from the outfeed end of the planer. Sunday, November 28. 2010Wood Shop and Other News - November 27, 2010Yesterday was a very busy day with the Wood Shop occupied and operating at near capacity. Lots of volunteers, lots of projects, lots of images!  Rabbeting John Faulhaber and Rich Witt were completing cutting the rabbet on new window frame pieces for Boston & Maine 1094. Later in the day, Rich, Buzz and I plunged eight mortises in the side pieces for these windows. Earlier, John had completed sanding and priming for a new letterboard piece for the Milwaukee Electric D 13 dump motor.  Windows Buzz Morisette continues to fit and finish windows for our MILW 01984 caboose whose bodywork recently recieved new paint. Here, trim and frames are being fit, tweaked, and fitted for each opening.  Ready to Prime Later in the afternoon a lot of the frames were ready for priming, along with beading and other trim pieces.  Lettering Jim Windmeier was applying lettering to some of his first half dozen newly constructed step boxes.  Parts And here is a Jim Windmeier photo - an overview of the pieces needed to build just one box (each part custom made) and an assembled end product. These classy step boxes will add to the convenience and safety of our visitors next season.  Another Door Tim Peters continued on another door for Chicago Rapid Transit 1797. I wonder if they are multiplying? Seems like I could count six exterior side and end doors and yet there always seems to be another deteriorated one coming into the shop for work.  Careful Sanding Victor Humphreys filled any spare moment with some careful sanding of yet more roof saddles being made for Chicago Aurora & Elgin 451. Earlier in the day we continued with some more prep work for the restoration of our Baltimore and Ohio wagon top boxcar. Victor is a key player for this project and has shown a lot of leadership.  That is a Surprise Victor Humphreys and Rich Witt seem to be asking "You want us to do WHAT with this new wood?" This is new stock delivered the previous day for making new tongue and groove roofing for the restoration of the LA ETB coach. We had thought maybe something over 600 feet would be needed, but as it turns out, closer to 1100 linear feet will be required. HMMM - -  Rip It Richard Schauer and Ray Piesciuk showed up and they were ready to WORK! Setting up the saw and shop aisles to cut sixteen foot long pieces of this required some juggling. But this is only the first step. Next will be planing to thickness, and then machining first the goove on one edge, followed by the tongue on the other.  Checking Each Piece Depending on how you look at it, these pieces look a lot longer than sixteen feet, if that is possible. Frank Sirinek picked up one of the new roof saddles for the 451, to check fit against the car roof, Mike Stauber and John Myhre were in the shop for awhile, Shelley Vanderschagen (from the passenger coach department) moved in and set up restoring a seat frame from the Santa Fe, Eric Lorenz and Ed Waytula were on the prowl, and I bet I forgot to mention others and their work. Yes, a very busy day. |

7009 number boards look good. Is there a way to turn a locomotive around at IRM? In case you ever had a mind to connect 7009 and 6847?
