I attempted another live steam test and it sprung a huge steam leak due to a failed seal at the top end of the site glass tube. It is now setting up with fresh rubber seal and a little clear silicone. I also tested the burner on Graves grain alcohol 95% pure (190 proof, same as Everclear).
 
I will try it again late tonight or tomorrow.

So I enlisted the help of Santa Clause to tend the boiler. I made him a small coal shovel with a brass blade that I dipped in a blackening solution I got from a gunsmith shop.
(new brass just wouldn't look right)

Not bad at all considering
 
My little Mrklin 5 decided to spit me in the face when the sightglass burst a leak :lol:

I am thankful mine wasn't blowing steam in my face when it let go.

Gil, this is important:
You did not remove hardened oil from the boilers casing.
It was the blued steels protective finish.
If you want to preserve the blueing (because it might tarnish unevenly now, greasy fingerprints etc) you should put that coat back on.
 
This is not clear paint, it is a varnish calles in Germany "zapon lack"
which is in english nitro.cellulose laquer i think.
The best is to get a spraycan wit this stuff, apllying is easier then.
It dries quick and leaves a superthin and even, clear coating.
 
btw. all blued steel parts did have this finish.
Thats why fireboxed are often so black: the varnish has burnt and hardened

Thanks, Mirko. This is very good information and I will get after it.
Nitrocellulose lacquer is still available here. Early automobiles were painted with it. Today it is still used on fine guitar finishes, at least when restoring guitars and other wood instruments from the 50's and 60's among other things.

Today's project:
I have added a new 16 minute video here and in the video section.

 
It took a couple hours of preparation and then burning alcohol for just under an hour.
 
I got a bit over 40 minutes of run time when the burner dried up.
The video involves warm up, start, run, electrical testing and demonstrating and a Marklin Saw accessory thanks to Maxwell (Mike).
 
Here:

 
 
 
Enjoy,
     Gil

For contrast, some before and after clean-up pictures....
 
Still more work to do, mostly very minute detailing, cleaning, and seals.
 
Enjoy,
