It is the "First Person Scale Model" site. The printer whom i just gotten that printed GM6C, mentioned that the creator of that site did a very good job and knows what he's doing. He deffinitely has some very interesting diesel and doodlebug projects, most of which i've never seen in brass. I'm not into diesels, but if i had more free time, i'd be getting that modified DL109 "Christine" for Rock Island Rocket printed for myself, that was a one cool diesel.

Yep. Same place I got mine. He is a college kid showing what 3d print will be to the hobby for sure. I have a bunch of files off there. Like thre S4. Once he is back up and designing, should be some interesting projects to appear

Cool site, had to look that one up!

I have a little more on the steam engine piping, I have seen those outlandish contraptions on the front of some of the NP locomotives, presumably the pre-heaters.
Here is the curious set of pipes on this small steam locomotive, I will guess for cooling purposes as you alluded to previously.
This needs to be one of the main locomotives on my layout because it was used extensively during my time period and on my track line I am modelling, due to its light weight and the wood truss bridge that was used to cross the St. Croix river could not carry the bigger loco's
The sand tubes are easy to identify here. The rest of them may be for two specific purposes, the top group of coils and the bottom group going under the cab.
Thanks again for your commentaries!

I've never seen a setup like that. You can see the upper lines are actually one single pipe zigzagging back and forth, so that's the cooling radiator. Both ends are going under the boiler and there is just barely visible a huge tank under that walkway but can't see which end is going to that tank. Surely one of those ends has to be coming out of the compressor, or compressors on the other side. The lines under the walkway are obviously coming out from the cab, so those are from controll valves on the engineers side, but there are sure a lot of them.
Looks like i found same or similar class steamer in Helena, Montana in a park in front of the station:
Unfortunately i didn't grab any shots from the other side. For my projects regarding those airlines i use ,020 brass wire which is easy to shape. One thing which seems to be missing on both locomotives is the water injector, but you see the water pipe going from the tender into the cab underneath. The injector in this case was inside the cab and a water pipe is visible (from the injector in the cab), coming out from the cab forward, making an "S" curve down to the walkway and then curving upwards to the valve into the boiler. Overall pretty simple setup, but that cooling radiator sticking up on the side of the walkway (on your picture) sure makes an interesting project to model.

This thread is giving me an unexpected and much appreciated education on steam engines!

Here is the left side of mine: much simpler, comes out by the compressor?
This turntable was located in St. Croix Falls, MN, and was part of the passenger/freight service from Wyoming MN to this village. Passed through many small towns and over something like 31 small trestles. Taken out about 1954.

You can see the line coming out of the lower cylinder of the compressor and turning directly up and turning into the cooling coil right in front of the compressor. The picture is very grainy and not very sharp, but it looks to me that the lower end of that coil has the line going directly into that tank below the walkway. Those two tanks have to be connected though. On that first picture of the right side of locomotive one of those lines going into that coil is either coming from the left tank , or from the compressor. I have to look inside the "Locomotive Cyclopedia" to maybe try making some sense of it. BTW i highly recommend having that book for anyone dabbling in model steam locomotives. One thing for sure, i don't remember seeing any steamers with cooling coils like that on both sides. We'll figure it out i think though.

I have some other photos if this one. This exact locomotive survived and is on display in St.Paul at the Jackson st roundhouse museum, I mean to visit. Maybe get down there this Thanksgiving season.

Yeah, me too!
I remember the locomotive in Dillworth MN from my youth which had me digging around for pictures of the piping…
This is a good one:

Thanks for the links! I think that steam engines are an engineering marvel, with so many moving parts that have to be absolutely in synch.

It was like designing a watch, everything had a purpose and had to be carefully tuned. Running works of art.

I saw a "Pacific" standing outside the roundhouse, but didn't know there was another steamer inside. I was there on Sunday, last year, and the museum was closed.

Here is the book i was referring to, as one worth having in the library for a steam locomotive affictionado:
This is the basic water delivery set up similar to what that Northern Pacific 4-6-0 had:
The only difference was that injector was inside the cab bolted to the side of the firebox wall.
The airbrake system for a modern steam locomotive
This drawing includes the Elesco water heater. Other than that it's similar to that NP steam locomotive. Of course the easiest way to figure out the piping is to find a real steam locomotive and follow along where all the piping goes. This is how i was able to figure out the Pennsy I1 decapod and by taking numerous pictures since i was able to bend down or stick my head under the boiler and the walkways. Nothing beats staring at the real thing for refference.

Those drawing are super helpful, that really spells it all out. I will buy myself a copy of that one for Christmas
THANKS!!!!!

Today a little more work on details for the Lehigh and New England F-1; main smoke box door hinges. I tried making them yesterday and failed.
The only part from yesterday i was able to use were the mounting plates for the smokebox door. For that complicated casting up front i initially used a flat piece of brass which i bent, but when i tried to trim it, it just broke. Today i took a different approach. Out of about 1,5mm thick brass sheet i cut flat bars, which then were slowly shaped with a cutting wheel on a Dremel tool and delicately squared off with mini files. The rest was cut away from different shapes and piece by piece was soldered onto the boiler with resistor soldering station:
They resemble the prototype, but i will not try to add more detail to them, they would have to be cast out of brass for that. Last pick an overall look so far:

Early day off of work yesterday and a late mornig to start today, so in the evening yesterday i sat down into that Lehigh and New England project. I trimmed those hinge details just a little, but didn't want to risk destroying them. Next were the inspection hatches on the side of the smokebox and sand dome hatches. Up front i soldered in that half round handrail on the front of the smokebox and lastly the bell. Bell will have to be resoldered since i missed the center mark. Hard to see but the headlight mounting seems to be going into the left, so i'll have to fix that also. A few picks:
The water drop under that inspection hatch was from washing. This thing has collected so much flux and dirt over time, that i grabbed it and scrubbed it with vinegar first and after, with a warm soapy water and an old tooth brush.

Currently working on the L&NE F-1 decapod and after straightening out that headlight turns out the bell is ok. Time then for the handrails running across the boiler:
Here both handrails are done:

Today work around the car, had to drill out one of the holes for wheel lug nuts, tap and put helicoil in it, light bulb and steering pump work, so not in the mood for the steamer after that. I did tackle that GM6C electric though as that is a much easier project. After gluing together the hood into one piece, i drilled out the main frame a little to get the Athearn HT-C trucks to fit. I decided not to invest in a used Kato SD40-2, since i already have the trucks and that will save me at least $100 on this model. This is what it looks like so far:
I had to drill holes for the marker lights in the hood on both ends, since the designer didn't make provision for them.
Locomotive sits almost exactly where i need it to, good thing this material glues easily with Lightning Bond and it's a strong bond.
I did screw up the steps though by glueing the rear pilot to the front and front pilot to the rear, that will be corrected eventually. The steps are almost exactly the same on both ends, except that blind lowest step; this set needs to be up front. At a train show in Bethlehem i found several great black and white 5x7 photographs taken of the beast soon after delivery and in service. These make nice addition to my research materials. All photographs taken by D.T. Walker:
That's it for today.
