For a long
time, I never cared about mechanics or wiring. It was something I couldn’t be bothered
with and I always subcontracted it to my brother when I was a kid and friends
later on. When something didn’t work properly, I would sideline it on the
shelves and not care anymore. That approach gave me the leisure to focus my
efforts on model building, scenery and planning. Sure, an attractive
proposition. However, comes a time when friends aren’t there, or you need things
to work right now or worse, the said friends won’t have the dedication to work
on some weird proposition.
Since I’ve
been working on Monk yard and other modules, I’ve had to become better at
soldering and wiring. I’m not very good, but at least, I’ve reached a decent
level where my work is passable and reliable. And if I mess something up, I know
why and how to fix it.
The same
wasn’t always true with locomotives. I would bash them, mess the electrical
stuff accidently and get a poor running engine out of what used to be a decent model.
Not a promising proposition when you wish to have good-looking custom
locomotives to play with. Over the last few years, I’ve been watching a lot of
people online that thinker with very old models, clean them, lube them, tune them
and make them run better. Most of these people, including Darth Santa Fe,
generally prefer to work with DC models. I use to laugh a little bit at that,
thinking they did so since they were more interested in mechanical stuff than
operation. But the reality is that you need to know that mechanical stuff first
before dabbling with DCC.
And there
is another aspect to that: the sheer simplicity of just having to lube a model,
run it and have fun. DCC has become a real pain in the rear. Dealing with dirty
track, poor sound, cutoffs and programming is extremely frustrating. This is
something for which I currently have no patience. Also, as I often mentioned, I
have a lot of old models that are DC and since they are oddballs, it makes no
sense dumping $200 dollars of electronics in them. For this reason, I have
embarked in fine tuning my DC stuff and the 4’ x 8’ layout is perfect for that.
On Sunday,
I decided to work on a very old project. My pair of custom detailed Athearn
blue box SW1200. I purchased the models back in high school around 1999 to
replicate Chemin de fer Charlevoix switchers. However, this project never went
nowhere and soon, as a teenager, I custom painted them in CN colors. During the
pandemic, I dug out these poorly painted models, stripped them to their bare
plastic and completely rebuilt them. It was a highly satisfying project, but I knew
the drive was good… or so I thought.

| Rebuilding my Athearn SW1200 electric motor |
Fast forward
a few years ago when I purchased replacement motors from Ebay. These were nice
can motors that ran very well and relatively silently. I tried to replace a
motor in one of the SW1200, but the surgery didn’t turn great when I grafted
the flywheels. They weren’t balanced at all and made the drive jerky.
Last
Sunday, I decided to simply rebuild the original drives and improve them. The
original Athearn motor was broken into parts. I couldn’t reassemble it because
the magnets touched the rotor. After some verification, I found out two plastic
tabs that kept the magnets at the right distance were broken. Some styrene replacement
tabs were glued in place and the motor was reassembled. Testing proved it was
running as good as the untouched motor of the second unit. I was extremely
proud to have salved a motor. After cleaning the commutator, adjusting the
brush and oiling the bearings, it was back in action.

I then
turned my attention to the trucks. Many sideframes had broken pins. I glued
them back, inserted a phosphore bronze pin in them and put a nice coat of flat
black on them. When I opened the gear tower and truck assembly, I discovered
these parts had never been lubed, except for oil in the wrong place. No wonder
they sounded like a coffee grinder! So everything went to the ultrasonic bath
for degreasing and cleaning. I had purchased new Athearn nickel plated wheels
years ago, so I proceeded to replace the sintered wheel with these new set. The
trucks were lubed and assembled, making them running much smoother than ever
before. |

The last
step was too degrease and repaint the metal chassis with satin black paint. I used
professional grade paint and let it cure for at least 24 hours. At this point,
I have refurbished trucks, well-maintained motors and a nice chassis.
Everything will need to be reassembled and new LED lighting installed. These
locomotives will probably never get a DCC decoders, but at least now they will
finally run on a layout after being shelf queens for over 27 years. They may no
longer be state of the art models, but this is not the point.
I’m getting
more confident in my work and this is what matters. Developing mechanical
skills is as important as the rest. I too often neglected that side of the
hobby and paid the price. There is a lot of satisfaction tinkering with an
older model and bringing it to its best condition. I’m discovering a new facet
to this hobby and it’s much more relaxing and enjoyable that I ever thought. Somewhat, DC is really relaxing in a world were electronics, sound and complicated stuff is no longer a novelty or making any sense.
