NS 6200 class
Finishing touches and final assembly of NS6228
|At the closure of any project there is always a host of chores that seem to keep you thinking "almost done" forever. Accept it and do the jobs. You won't be finished until they are all done.
A last minute design change was sparked when I did a test assembly and light accidentally fell into the drivers cab.
I hadn't expected the absence of a boiler backhead to be very conspicuous in the dark cab but I was wrong. The silvery weight was shinily present. I could do two things. Paint the weight or provide a backhead. I chose the latter. I had to order two hook couplers anyway so I included a boiler backhead in the order.
|A week later this shining beauty arrived.|
|As the motor and the drive are in the way I needed to cut it ...|
|... and throw the lower part away :-(|
|After some filing|
|I gave it a quick base coat and test fitted it.|
|Black coat ...|
|... followed by a dark gray wash to get some depth in the backhead. I also scraped away the paint where the parts needed to stay brass. Then I gave it a dull clear coat.|
Getting the backhead in place in a fully assembled superstructure proved to be a challenge.
After several attempts on getting the thing in the correct place and remain there until the glue had set, I found a simple solution.
I positioned strips of scrap brass on the rear and carefully lined them out to be exactly 0.5 mm from the edge. I fixed them in place by adding a drop of thin CA.
The brass strips would now take care of the positioning of the backhead in the boiler.
|Like this. Once in place two drops of CA fixed the backhead temporarily in place.|
|Then epoxy was mixed and added to make the bond permanent.|
|Next I turned to the couplers. They are functional hook couplers. They can be drawn out by trailing cars to allow for sharp curves. The spring draws the hook back in.|
|There is a square hole in the buffer beam. I needed to open it up a little.|
|The spring was added and it was secured by a piece of wire that runs through a hole in the back of the stem, barely visible at the left end of the spring.|
|Test fitting is essential.|
|Another chore down!|
|After all working on the superstructure some touching up of the paint work was necessary. Not much though.|
|Coal was mixed with Ballast Magic of Deluxe Materials|
|and poured into the coal bunker. It is then sprayed with water and it set in place.|
At last: Final Assembly
Final assembly consists of only three steps.
The superstructure moves easily over the chassis, starting from the back.
|The secret screw under the safety dome is screwed tight|
and then the screw under the leading axle.
The project is done.
