Now I won't be able to talk for years. This is beautiful. Great workmanship.

With the air tanks on top of the boiler she looks like a pseudo camelback. well done sir.
Thanks for the kind remarks, guys! Goldth
At the rate I'm working, I'm surprised that anybody's even bothering to follow this. Crazy

Steve, I have to admit that I never used to care much for camelbacks at all, but after some long conversations with biL, I started to warm to them somewhat. After seeing the ones that you've done, I've become quite the fan of them, though not, perhaps, to the point where they'll be powering any of my trains. After all, that would involve importing another type of fuel, not something a railroad trying to keep things to common standards would likely do. Your advantage is in your locale, with coalfields of various types close at hand.

Wayne
Wayne, a couple of questions for you. Do use the main drivers as pick ups too? I would think so? Did you add wipers there also?

I like when something that has been in the long forgotten pile can be brought back to life Thumbsup This build is looking great. Applause

Mark
Well doc,, You can burn just about anything in a Wooten firebox, soft coal, hard coal, dirt, garbage, wood,,,, at the end of steam what ever they had went into the furnace.

Mark

As far as I'm aware, Mark, all Bachmann steamers come with all-wheel pick-up on their drivers. The wipers bear against the rear faces of the drivers' tires, with the current directed to a circuit board in the tender (where DCC users can add a decoder), and then on to the motor.
Since my layout is strictly DC, I remove the circuit board completely, as loco response is better on DC without that circuitry in place. The locomotive is then re-wired so that it will run whether or not the tender is connected. This makes testing, repairs, or trouble shooting easier, whether on the layout or on the workbench. With the mechanism upside down on the workbench and power leads connected to the motor, it's easy to lube the axle bearings, valve gear, and siderods while the loco is running. This feature is also useful in the paint booth, where turning drivers help to avoid unpainted areas where static siderods would normally shield portions of the drivers.
The all-wheel pick-up on the tender is simply another way to increase operational reliability.

I have added all-wheel pick-up to some of my other steamers, but most of those are older models with limited original pick-ups, as is the case with most brass locomotives.
Even on unpowered Atlas frogs, this little 0-6-0 never misses a beat (and it's a pretty-good puller, too)...

Wayne,

you have done a very excellent job with the "Canadification"* of the Spectrum 2-6-6-2. Thumbsup Applause Worship

Cheers Lutz


* Or what else i should call it?
Thanks, Lutz. Goldth

That's a fairly apt term, I think, and also demonstrates a good grasp of my language....wish I was capable of simply expressing myself in German, let alone creating believeable words in your native tongue. Crazy

Wayne
Wayne,

don't worry, be clicky: <!-- m --><a class="postlink" href="http://dict.leo.org/german-english/">http://dict.leo.org/german-english/</a><!-- m -->
And you will see, even complex German terms lost their Schrecken. Wink
We Germans have the bad habit to create words like tapeworms. And sometimes this bad habit will create new words Icon_idea
E.g. the term "Luftpumpendruckregler". A dictionary will fail here until you have a special technical dictionary. So it is the best way to tackle the tapeworm words by cutting them up:
Luft = air
pumpe = pump or compressor
druck = pressure
regler = governor

You have already fitted a airpump governor onto your 2-6-6-2, haven't you?


Cheers Lutz
Well, I'm not totally helpless with the German language, and recognised "air" and "pump", but got tripped-up wondering about "druck" being a separate term, even though I interpreted "regler" as regulator.
The locomotive does have a couple of fittings on the smokebox front, but they certainly don't look like governors....must be located somewhere else....yeah, that's it...they're somewhere else. Misngth Crazy
I did make governors for the airpumps on my Ten Wheelers, though, so I'm well aware of what you speak:

As for the 2-6-6-2, work on the tender has seen some progress. Because the tender was shortened, mostly in the area of the cistern, and then the coal bunker extended into the remaining cistern's deck area, layout of the components required some planning.
The back-up light placement was really the problem, as most of the other details had to go in certain places, leaving only a site high on the rear of the coal bunker extension.
I used a brass headlight from PSC, soldering it to a homemade brass bracket, then adding .010"x.030" brass strip (from Detail Associates) as support braces. A piece of .008" phosphor bronze wire (Tichy) represents more Bx armoured cable, and it will be connected to a junction box on one of the tender's handrails...

[Image: GRS%202-6-6-2...%20095_1.jpg]

[Image: GRS%202-6-6-2...%20096.jpg]

The angled portion of the bracket, behind the lamp casting, slips into a slot cut between the rear of the bunker extension and the slopesheet inside the bunker. The braces have been drilled to accept a short length of .012" wire, the exposed ends of which will represent the heads of mounting bolts - these were added after the light and bracket had been installed.

I set out to use Lutz's method of creating a diaphragm connection between cab and tender, but ended-up simplifying it to non-moving parts, some on the loco and some on the front of the tender. While not as elegant as his solution, it at least gets rid of the gap between loco and tender, and still allows movement around the tightest of my mainline curves.

[Image: GRS%202-6-6-2...%20100.jpg]

Here's what's left of Bachmann's circuitry inside the tender....

The sides of the tender still need to have rivet decals applied, but I have something else that will also need rivets and will do both when the other one is ready, too.

Wayne
Still plodding along with this locomotive, which right from the start was intended to be a locomotive and tender with a tender behind. Crazy Misngth

I've shown the locomotive and its tender, now here's the tender behind. It started as a standard Model Die Casting coal tender...

[Image: GRS%202-6-6-2...%20062.jpg]

I added some supports, cut from .060" sheet styrene, in preparation for adding a new deck...

[Image: GRS%202-6-6-2...%20064.jpg]

...then, once the cement had cured, sanded them flush with the top of the tender's sides...

[Image: GRS%202-6-6-2...%20066.jpg]

I also added an extension to the front of the cistern, then topped the whole shebang with a new deck cut from more .060" sheet...

[Image: GRS%202-6-6-2...%20081.jpg]

Added atop the new deck was a bead edge made from Evergreen 2"x2"HO strip styrene.
All of the rivets were sanded off the tender's body, then automotive spot putty was used to fill any blemishes and anomalies in the casting - this stuff is extremely easy to use, and I found it to be superior to similar products intended strictly for hobby use.

[Image: GRS%202-6-6-2...%20110.jpg]

[Image: GRS%202-6-6-2...%20109.jpg]

I also added all-wheel pick-up added to its trucks, like the main tender shown previously. I've modified the front end to extend it closer to the main tender, and added wires from the truck pick-ups to allow it to be electrically connected to the main tender and thereby, also to the locomotive. This 28-wheel pick-up should ensure electrical continuity to the motor. Goldth The trucks are from an Athearn Mikado.

Next, it was time to add some details. The front end got a brake wheel, useful on a tender which would need to be uncoupled and parked while the loco and main tender were turned on a turntable too short to accommodate all three. This was the reason the main tender was shortened in the first place, too.
I also added assorted grabirons and steps to make things a little easier for the fireman and brakeman. The platform sticking out from the front of the deck matches a similar one on the rear of the main tender - basically a stub-roofwalk to allow the fireman easy access from deck-to-deck at water stops...

[Image: GRS%202-6-6-2...%20114.jpg]

[Image: GRS%202-6-6-2...%20117.jpg]

Here, the auxiliary tender, at left, is coupled to the main tender, and the electrical pick-up wires plugged into the receptacles on the rear of the latter...

[Image: GRS%202-6-6-2...%20118.jpg]

The rear of the tender got a scratchbuilt ladder, a back-up light from PSC, and a pilot - this one is from a Bachmann USRA Light 4-8-2, and its use here is based on a similar set-up used on two NYC Ten Wheelers operating out of St. Thomas, Ontario. Looks like I should add another horizontal handrail for anyone needing to cross-over on the endbeam, too 35 ...

[Image: GRS%202-6-6-2...%20115.jpg]

The tender deck got a music wire handrail around most of its perimeter. The handrail stanchions are Cal-Scale, while the tender hatches are from Precision Scale. The hatch rests were bent from Detail Associates .010"x.030" flat brass bar, and the stand for the back-up light was made from a piece of stamped-brass ladder stock...

[Image: GRS%202-6-6-2...%20116.jpg]

Both tenders will get rivet decals applied to their sides, and the auxiliary tender will also have them applied to its deck.

Wayne
The auxiliary tender is a nice addition to that hog. Next week I was going to officially start the "tender Tuesday " thread. Be sure to post a shot or two of it sir.
I've edited my previous post to add some photos of the initial alterations made to the auxiliary tender.

Still working on this locomotive as the Challenge deadline draws near.
I added some rivet decals to the main tender, to help hide the joint where the section was removed...

[Image: GRS%202-6-6-2...%20121.jpg]

...along with some treadplate detail...

[Image: GRS%202-6-6-2...%20123.jpg]

The auxiliary tender got more of the same...

As I learned with the Seaboard boxcar in Part III of my Challenge, even repeated applications of Solvaset will not settle the rivet decals well and I had several instances where entire strips of rivets would fall off, even with careful handling. Once all the rivets seemed to at least be staying in place (but with upturned edges and lots of silvering and bubbles, both indications of poor adhesion), I very carefully applied MEK to each river strip and tread plate decal. This requires a light and rapid pass, using a fairly small brush to avoid carrying too much solvent at one time. Where areas are missed on the first pass, go back a few minutes later to apply more, so that there's no excess accumulation of it: if the area remains wet for more than a few seconds, the individual rivets (tiny blobs of resin) will separate from the decal film. I purposely applied the rivet decals on unpainted styrene, most of it not at all glossy due to sanding. While such a surface does encourage silvering (trapped air), the bare styrene seems to react, along with the decal film, to create a much better bond. I'm tempted to say that the rivet decals are cemented in place.

A coat of Floquil Gray Primer made the rivet details "pop"...

[Image: GRS%202-6-6-2...%20128.jpg]

...and gave a uniform finish to the disparate materials used in construction...

Since I'm planning to paint this locomotive using Scalecoat paint, the running gear modifications were brush painted directly on the unprimed plastic or brass. It'll get airbrushed at the same time as the tenders, although I may run out of time to get the lettering done before the Challenge ends. If that's the case, I'll still finish this build in this thread.

Wayne
That's one very nicely done loco you got there sir. Thumbsup All the piping, extra compressors, and tanks give here some real visual weight. I hope she doesn't bend the rails on your layout when you run her.
Thanks, Steve. While it does have some heft to it, it's spread over a lot of wheels, and as a result, is not the great puller I had hoped it would be. The wipers added to the tender trucks don't help a lot with that, either. There's a fair amount of room left inside the back end of the boiler/firebox area and, of course, in the cab, but adding weight there would imbalance it, likely to the further detriment of her pulling ability.
