I've been working on the same loco.
This is what I have so far.
A roof sitting on four posts will be added by the time I'm finished.

A shot of the backend.
My model is 1/2" scale BTW.
The back will remain open so the driver can get in ok.

Progress has been slow. But that dead time is always time to think about HOW to do a project.
I am back at it and have decided to try making templates for the side walls out of paper in order to do a test fitting.
I am using photoshop, but I think a free program like Gimp would like serve just as well.
Ok, so the cut out piece are scanned so that I can get a 1-1 image.





These are then aligned and I used "guides" the blue lines to define my panel area.





Now the last stage is to make a selection, or mask, that I can drop some filler into,
and I have a pattern I can print and cut out and tape together with my actual loco pieces.





I would have done more work, but I had a software failure. Lost ALL my work.
But I do have these screen grabs I can refer to.
I will simply take that last one and re-scale it to fit 1-1- and see how it looks.
Slow progress, but a real learning experience for using a computer to make templates for Real models. ;)

That looks great! Do you have some more construction shots somewhere?
I am going to remove that awkward exhaust stack too. I want to build one with a muffler on it.
I am planning on leaving a lot of detail on the hood as sort of trick detail.
Even if it is not correct, people will look and go wow, nice detail on that... uhh... errr.. nice detail! :D
I have only put clip leads on mine. How do you feel about its running ability and load bearing ability?

Several years ago I did buy a 550-something page book titled Beginning Gimp by a gal who has worked on development of the program. I often learn more easily from books than from online computer programs or videos.

Most of what I am doing is very basic stuff.
Just playing with the idea of very lazy modeling techniques for noobs like me. :P

    My loco rebuild to 1/2" scale has been trial and error, no plans, except a vision in my minds eye. 
I raised the hood almost a 1/4" with styrene plastic.
I feel this gives a more believable impression of a hood that could actually hold a engine and transmission.
As far as detail on the hood, the look of removable panels will be added.
The cab will have a roof but no window glass. Roll down canvas curtains will be modeled to keep the driver warm and dry.
 
    I bought my loco used off ebay. It ran ok when I first tested it.
After cleaning the wheels and oiling the gears and axles with Labelle 108 plastic compatable oil, it ran much better.
Now that I've run it around the layout several times, it runs slow and smooth.
The mechanism of my loco is a bit noisy.

    Since the loco is only two wheel drive it doesn't have the pulling power to handle the grades on my layout.
Adding some weight may improve the pulling power and improve electrical contact with the rails.  
I plan to use it as a switching loco on level ground.
 
    I hope you find this info useful,  Larry Gant

Thanks Larry,

all good info.

It's certainly a toy train set loco, that's for sure.
I plan to use it with very short trains.
But it isn't much different than most locos as far as the drive.
Did I say most locos? I meant, most cheap toy train locos :)

It's just ye olde motor with a worm gear on the shaft and a big gear on the wheel axle,
which has always worked for many toy trains for decades.

I am thinking of using some plastic safe grease on the gears.
Something a little bit thicker than oil, but that is just me. :P

Side note:

You know when you haven't done anything model wise with trains in a while...

Somehow you packed it all up neatly...

There are at least 3 X-acto knife handles in there...

You have all this sheet plastic that needs cutting...

Where the heck did I put it?

I am discovering the joys of cutting plastic.

I seem to be cutting pieces that are not exactly square. I'm having fun, but there has to be a better way.

Or, does everyone use thin plastic and then sand the edge down flat with the nearest 90 degree surface, so it matches up?

Practice loco progresses along, be it very slowly. :)
