Mid-July 2015 C&NW 1385 Update

Although updates have been a bit sparse of late, activity on the Chicago & North Western #1385 has continued forging ahead. The work completed in the last few months is not the kind that make great headlines, yet all of it is equally important toward achieving an operational 1385. Without further delay, here is the latest:

  • The driving boxes, shoes, wedges and hub liners are all now complete, save any modifications needed for grease or oil lubrication and any adjustments found necessary at final assembly of installing the drivers into the frame.
  • The footplate has been fitted, holes reamed, and tapered bolts installed to hold it place.
  • The locomotive’s spring rigging has been fully rebuilt. It is being installed onto the frame and will be stored in place unless it proves to be in the way of other work.
  • Most recently, work has begun on the machining and renewal of the connecting rods and bushings.

Other tasks coming up in the near future (In no particular order) include:

  • Rebuilding of the front truck.  The wheels on the front truck are currently being assessed as to whether they can simply be re-profiled and still offer adequate service life, or whether replacement is necessary.
  • Renewal and machining of the valve cages.
  • Cleaning/polishing of the finished rods.
  • Boring of the cylinders.
  • Cleaning and test fitting of the valve gear to determine wear and repairs needed.

The 1385’s new boiler is nearing the end of the engineering review phase and is expected to enter the build phase within the next several months. The boiler will be discussed further in a future post.

Brasses, Bolts, and More

To start this post is some photographs and videos taken earlier this year but never posted until now. These document some of the work that was performed at Hercules Precision, LLC in Baraboo on C&NW 1385’s crown brasses and driving boxes.

A driving box is a box-shaped casting which is fitted to slide vertically in the pedestals of the locomotive frame. The driving boxes hold a brass that rests on the journal of the driving axle. The weight of the boiler, locomotive frame, and the cylinders rests upon the driving boxes, with the exception of the weight that is carried by the 1385’s leading truck.

Inspections revealed one crown brass out of the six required replacement. The remaining five had a good amount of service life remaining.

In more recent photos, taken June 17, 2015 at SPEC Machine, the finished driving boxes can be seen being installed into the frame pedestals. Additional photos show holes continuing to be reamed for the many custom tapered bolts being created and installed as the frame and it’s components are reassembled.

Also of note in the photos is the new footplate that has been installed. The original was found to have a significant crack (see March 30, 2014 post). The drawbar, which connects to the tender and thereby the rest of the train, is attached to the footplate. Given the heavy stresses these parts are placed under, it was determined that for safety reasons, it was best to replace the footplate entirely rather than attempt repair of the original casting.

Frame Painting Complete

The painting of Chicago & North Western #1385’s frame was completed on Saturday, Jan. 3rd. Pete Deets, one of the 1385 Task Force members had this to say:

Words fail me as THANK YOU doesn’t seem to be near enough. We had 2 fantastic days of volunteer-ism, productive work and lots of fun. In that time we applied 2 basecoats and one topcoat of paint on the 1385’s frame. At the risk of leaving someone out I can say we had the help of Bobbie, Clayton, Ed, 2 Mikes, 2 Jeff’s, 2 Al’s,, Kayla, Steve, Dick, Gary, Dylan, Robert, Larry, Brian, Ron & Kyle. Tom from Grote’s [Howard Grote & Sons] was a great tutor and easy taskmaster. Believe it or not we have put something permanently back on the 1385!

Plans for more volunteer sessions are in the works.

Photos can’t do justice to all the work completed in the past year of cleaning, scraping, engineering, welding, milling new parts, painting, and so on, but the below before-and-after photos are a nice reminder of the progress made. At the time of the first photo on January 11, 2014, the 1385’s running gear had just recently arrived at SPEC Machine and was in the process of being dissassembled.

As the second photo shows, the frame now features two coats of primer and a new glossy black topcoat. There are also many spring-rigging parts already painted to match.

New Year Begins with a Splash (of Paint)

The rebuild of the Chicago & North Western steam locomotive is in full swing as of the start of 2015. There are a number of sub-projects at various stages of progression all happening simultaneously involving the frame, driving boxes, wheels, cab and boiler. This post will cover the frame, but additional posts covering other aspects will be posted in the following days and weeks.

Painting of the frame began on January 2, 2015 and is continuing on January 3rd as this post is being written. Mid-Continent volunteers were joined by Tom Hartling of Howard Grote & Sons, a Madison-area company specializing in protective coatings. Howard Grote & Sons volunteered to provide Mid-Continent with Hartling’s expertise in mixing and applying the epoxy primer and urethane topcoat paint used (Carbothane 134 for those interested).

Work started at about 7 AM on Friday the 2nd, with the first of two coats of primer, the first being black in color. After a break for lunch, the second coat, gray in color, was applied with work mostly wrapping up by 4:30 PM. Application of the topcoat was left for Saturday January 3rd.

Work on Friday went quickly thanks to an enthusiastic response by volunteers. Mid-Continent volunteers joining in on Friday were: Mike Wahl, Pete Deets, Ron Kokemuller, Jeff Huttenburg, Bobbie Wagner, Kyle Gherke, Robert Hasheider, Mike Laabs, Larry Stanley, Rich Gruber, Brian Allen, Al Joyce, and Jeffrey Lentz. These MCRM members were also joined by Steve Roudebush (of SPEC Machine), Kayla Roudebush, and Clayton Hendrickson.

Nearly 100 additional photos of the January 2nd workday are available on photographer Brian Allen’s Flickr photo album. The video below is a one-minute timelapse showing the roughly three hours of work adding the second coat of primer.

Weld Repairs and Additional Progress at SPEC Machine

Work on the restoration of Mid-Continent’s ex-C&NW R-1 class ALCO locomotive, No. 1385, has quietly progressed through the summer months at SPEC Machine near Middleton, Wisconsin. Project photographer Brian Allen stopped by SPEC Machine’s shop on Tuesday, September 16, 2014 to provide some views of the recent efforts.

The photos catalog the extensive weld repairs completed on the locomotive’s frame over the summer (see July 1 post for additional details).

On the day of the visit, work and discussion was centered on the spring rigging equalizers. A locomotive’s spring rigging distributes the weight of the locomotive over the various wheels. Without equalizers, even small undulations in track elevation could cause substantial variations in how much weight is being supported by a given wheel. Such large variations would cause undue stresses to both locomotive and rail.

In this series of photos, you’ll also see some components in fresh, glossy black paint. After months of stripping away layers of old paint and rust from the locomotive’s parts to reveal the condition of the underlying metal, seeing fresh paint being reapplied is a welcome sight!
