Building a Live Steam Locomotive - the Mikado Project
February 2015 - With the locomotive functionally complete and running, activities turn to the details -- adding in cosmetic items such as air tanks, cab roof, lighting, with more work to come. August 2014 - With the locomotive not in the shop for the summer, it is very hard to work on it. We have shifted to Summer running and Winter shop work, making updates to this site even more sporadic. October 2013 - The successful fall running season is over with the annual "Boiler Blowdown" last run. Time to put the loco back in the shop for the winter, and to finish the tender for next spring. September 2013 - work shifts from the tender back to the engine & jacketing in preperation for the fall train meets. June 2013 - we continue to work on the Tender and Tender Trucks. September 2012 First fire-up! The engine has made it out of the basement, a fire light and steam was raised! See folder "Operations" for details. Construction photos of a 1.6" scale, 7.5" gage live steam USRA Heavy Mikado locomotive, wheel arrangement 2-8-2. Under construction in my basement under the expert tutelage of Bill W., retired master machinist. I have chosen the home road for this locomotive, it is a Frisco 4100-series engine, number 4166 (a 'ghost' engine, the 4100 series stopped after 4164). Note: Most of the pictures in this album are in reverse order, with the newest developments first.

Operations and Alterations - After years of effort, we run the engine!

September 2014 Engine and new Tender ply the tracks with much success. A couple issues pop up which we address. October 2013 Several more runs at the SLLS track and Big Creek & Southern reveal a fine running engine. Also pictures of the first fire-up of Frisco 4166 September 2012. First throttle pull at the St. Louis Live Steamers track. A three-day break-in run at the Big Creek & Southern and last run for the season. At the time, I used a borrowed tender from a friend (still needed to build one).
Assembly  |  Total images: 85
Although there is no 'Section A' in the prints, I need a place to record the assembling of the locomotive. 2014: Tender, Tender Trucks, Fuel Tank, Air Tanks, Cab Roof, Numbers and Letters. Fall 2013: boiler accessories including jacketing, handrails, domes. Winter 2011: Boiler Fit, Remove, Fit Remove, Ashpan installation, firedoor, front-end work. Winter 2011.

Painting  |  Total images: 38
Another non-print section, but another milestone event. 2014: Sealing the Tender, Numbering and lettering the engine (and a near disaster on the cab lettering), Tender Trucks. August 2013 - The paint tent is set up again for another round of painting. Parts have been Prepared, Primered and Painted. Now that this big batch is completed, most parts are now painted as they are completed, so you'll find them in their respective sections.

Close to being Finished! Boiler Accessories.

Fire pan modified, completed, for a square burner and damper assembly Feb 2011. Fire pan modified, completed, for a larger atomizer opening in fall 2010.

Section 17 - Tender Trucks
Section 17 - Tender Trucks  |  Total images: 136
Usable! Tender Trucks. 2014 - The trucks have been finished, assembled and painted enough to be runable. We did not design and fabricate the dozens of small parts to put operation brakes on them. We will do that later. Happy to report the trucks work great and have not given any issue running over the track. July 2013 Axle box machining in progress. June 2013 Back from being welded into a contiguous piece, Bill finished the machining of the Frames. Construction Started December 2012! I picked up a set of 3-axle commonwealth trucks in November 2008 which I will use instead of the supplied USRA bettendorfs. One problem: the homemade castings do not have an engineering print with them. I had to make prints and Bill had to figure out how to machine them.

Section 18 - Tender  |  Total images: 160
Completed! Tender. 2015 Added the "doghouse" - the brakemans shack to the tender deck, a unique Frisco detail, and backup light. 2014 - Finished over the winter and in service! Some detail work remains. The July 2013 Assembly continues, riveting and welding are in progress. I have already learned one lesson: Cut the tender frame to length AFTER the tank is made. Maybe you will do better than I did, but my tank is a about 1" shorter than planned-making accurate bends in the sheet sides is hard! After using a borrowed tender for the first fire-up of the locomotive, all attention is turned to fabricating one this winter. November 2012 - raw stock for Tender Frame cut. Steel side sheets for tender tank laser cut. Fiberglass Tender received 2003. June 2009 - I am thinking of making a tender instead of using the fiberglass one since the 3 axle trucks I have will not fit under the frame.

Section 19 - Misc  |  Total images: 14
Misc. Stuff that doesn't have a particular home. Like the Lubricator. And hand rails. And a Bell, and whistle, and lettering, and couplers, and....and...and all that other stuff.
 Some assembly required!  The cast iron spoked drive wheels are in front with the pilot (front) and trailing wheels behind it.  Painted red in machinist layout fluid is the engine frame -- 13/16  Some assembly required!  Here are some of the 150+ castings that need to be machined, assembled and painted to complete the locomotive.  Most of the castings are aluminum, the rest are bronze.  On the right is the smokebox cover, tender water hatch. The smokestack and sandbox are in the back. On the left are the axle boxes for the wheels.
