Mid-June 2019 Boiler Progress

Chicago & North Western #1385’s boiler continues to see steady progress. Since the last update, the boiler has been moved across the Continental Fabricators shop floor and is now on the positioner.  With the boiler now on the positioner, it can be rotated to allow workers to put it into the best position for welding and assembly in areas that would otherwise be difficult to access.

Installation of the crown stays is also in process. Crown stays are the staybolts that connect the wrapper sheets – which wrap around the firebox – to the crown sheet (i.e. the top of the firebox). The crown sheet is directly above the fire and is the hottest part of the firebox.

The crown stays (shown in green) support the crown sheet at the top of the firebox, preventing it from bowing inward from the immense pressures.

 

You Can Help Get C&NW 1385 Back in Service

Ever since the C&NW No. 1385 restoration was resumed in 2011 work has progressed steadily thanks in large part the financial support of the 1385 project’s enthusiastic followers. That financial backing has allowed hired professional machinists to work on the project 5-days-a-week and allowed progress to occur exponentially faster than could be accomplished by volunteers alone.

As we head in the home stretch we’re asking for your continued support so that the 1385 restoration can continue moving forward without delay. Please consider joining the growing list of nearly 1,000 project contributors by donating today. You can do so by visiting our Donation Page and specifying in the donation form that you want your contribution to support C&NW #1385.

Donating is easy thanks to our online donation form which accepts all major credit cards and Paypal, or you can use our printable donation form to send with your mailed contribution. Thank you for helping us get this far!

With your help this will soon be a common scene at Mid-Continent Railway Museum.

Late-May 2019 Boiler Progress

Work on Mid-Continent Railway Museum’s Chicago & North Western #1385 locomotive during the month of May has consisted of stay installation, stay installation, and more stay installation. With over 900 staybolts to be applied, this process represents one of the more time-intensive portions of the new boiler production. Each weld must be made with great care and precision to avoid leaks and ensure proper strength when the boiler is under operating pressure.

Continental Fabricator’s Tom G. peered into the belly of the beast on May 29th to take these photos of stay installation progress on the inside of 1385’s firebox.

Here are the latest photos of C&NW #1385’s new boiler, courtesy of Continental Fabricators in St. Louis. The photos were taken on May 20, 2019.

The backhead stays are all installed and they are currently completing welding on them.

The large horizontal braces that were previously attached to the outsides of the side sheets and backhead are now being removed as progress continues. The braces were installed temporarily to prevent warping from the heat generated during welding.

The throat sheet – the sheet that connects the firebox to the bottom of the boiler barrel – has all of its rigid stays installed and is in the process of welding.

 

Early-May 2019 Boiler Progress

Since we have a new month and new Monday we also have a new update! Tom G. from Continental Fabricators writes:

Here is the latest update..
All but 22 backhead stays are installed, most of them have the root pass in and  working on completing the welding.

The side sheet stays are also moving along.
Throat sheet flexible stay installation to start this week…

Included with the update was two photos.
