Back to work on the K-2

I'm back to work on the K-2 Pacific conversion, starting with an old Atlas/Rivarossi Pacific I picked up from Ebay.

The tender is just about done, so I turned my attention to the boiler.
At this point I'm just experimenting with my steam skills.

Here's what we started with...


The WM K-2 has a larger sand dome that's located closer to the steam dome, and the bell should be located between the smoke stack and the sand dome, sort of like this...



I electronically "spliced" the boiler of a Bachmann Spectrum Consolidation on the front there to give you an idea of what I'm after.  I'd still like to do that, but I'll need two Bachmann shells, which I don't have, and with the budget being limited, I'll just make do with what I have.  So, I started by relocating the headlight.


Using a sharp Xacto blade, I simply trimmed the original casting from the nose of the smoke box.  I then drilled a small hole in the top edge of the smoke box door to run the wires for the lamp into the boiler shell.
I used a grain of rice bulb, 1.5 volts, which was much smaller than the headlight housing. I filled the gap in with gloss finish Mod Podge to create a full lens, which also has the effect of making the light appear brighter.
If I was a little brighter, I would have painted the inside of the housing silver, which would have added to the brightness... I also cut off the stock pilot to make it ready for a working coupler and a plow per WM practice.

Next, I turned my attention to the sand dome, which had to go.  I picked up Mr. Dremel, and went to work.

I used a small file to square up the hole.  You can also see the back of the headlight here. The wire for the grain of rice bulb angles down into the top of the smoke box. To cover it up and prevent light leaks, I filled the area in with matte finish Mod Podge and let it dry. I then finished it with a bit of flat black acrylic paint. Eventually the smokebox will get a gun metal color.

One of the problems with the Rivarossi Pacific is that the nose tends to be a bit light.  There's a brass weight in the smoke box, which was designed to hold the original light bulb, and it is fine where it is.  But there's a gap of about 1/4" between it and the motor frame, directly below the existing sand dome.  This was handy, because it gave me someplace to add some weight.  So, I filled the hole where the old sand dome came out with a chunk of lead I have in the garage, left over from a leaky old sewer pipe in the house that was replaced.

First I scrubbed 90 years worth of turds off of it, then used the Dremel to file it to roughly the shape of the boiler.

I then used jeweler's files and very fine grit sandpaper to finish it off.
I also used some strip styrene to modify the walk boards. Next I need to fashion a new sand dome out of lead.  I'm going to try to fashion an original out of wood or styrene, then make a mold with some plaster to pour the lead into.  That will give me a little more weight on the drivers.
Now I just have to dig up a photo of the engineer's side of the damn thing!

To get juice to the headlight, I needed to add a resistor. There isn't much room inside the shell, so I used some brass rod to make some piping, as well as carry the current. I put the resistor above the air pumps. Once it's painted it will look like part of the pump system.

I hooked it up to the decoder, and it works fine, although there's a little flicker due to the less than ideal pick up system of the engine.  I have a capacitor laying around, should that be added between the bulb and the resistor, or does that matter?

Once I got the wires situated to eliminate some binding, it ran well around the layout.  Next I want to add a back up light to the tender, though I don't have much in the way of a proper housing for it...  I'll see what I can come up with.

I also sculpted a sand dome out of another piece of lead.  There's a coat of paint drying on the boiler shell now...

Looking good, the method of hiding the resistor is ingenious.

These help?  Notice placement of headlights.

wm,

Great work so far.  You know I used to be Steamguy, so you can tell how much I appreciate your effort.  Are you planning a re-motor which will make this loco last forever?

If you need any parts let me know, and I have a bunch of spares I use for my main running Rivarossi Pacifics so all you need to do is call.

Do not forget to send pix when you are done.

The other important point is that you appreciate the old locomotives made years ago, and by modifying them you make them look so goooooooddddd!!!!!

Way to go

Funny about engineer's side views of K2's, isn't it? I have David Sweetland's Western Maryland in Color, and all of the eight or ten photos of K2's are from the fireman's side.

However, there are some engineer's side views here: http://www.northeast.railfan.net/wm_steam.html

I found what I needed in "Fireballs and Black Diamonds."  It turns out that the engineer's side of the oil fired engines is different than on the coal fired ones.  I found both views of #201, an oil burner, which is what I'm going to number this one (the decoder address is already set!)

Here's a glance at the freshly painted boiler...

Painted with gloss black, with graphite on the smoke box and dirty silver/aluminum on the firebox... Much touching up remains. The gloss coat is for decaling.

It's hard to see in this shot, but I added separate grabs down the side of the boiler, and put the top of the original sand dome on top of the lead blob I made to give it some detail.

I'm going to see if it's dry enough to decal the cab number and striping on during "Extreme Trains" tonight!  I also have to finish the pilot (MT coupler and a plow assembly).

Once that's done and she dries for 24 hours, I'll hit the roof and cab windows with oxide red, then it gets dullcoated and re-assembled!

Getting closer...


Still have some more touching up, but the lettering is now on... I ended up using 204 instead of 201... decals were already in the right order ;) 

I also completely reworked the top of the oil bunker to make it more closely match some proto photos I recently found in my library...  Next project will be the pilot, the number board for the smoke box, and the final touch ups.  Then I'm going to see about weathering the running gear with an airbrush following David Popp's method in the GMR 2008.

We shall see!

Yikes, never thought I'd see "airbrush" and "Lee" in the same post...

Nice work, all the same! Great to see truly classic old equipment getting a new lease on life.

Steam sucks........ RSs and GPs forever.... ;D   Just kidding Lee. Looks great.




If it matters any, I have learned where the PRR used to dump their firepans on the Chestertown and Centreville lines. The evidence remains to this day.

So Lee is a steam head now, what's next?

One thing I have noticed is that every steam locomotive is different.

Great work there Lee.  You better hope you don't get the bug to do a I-2!
