I've been behind on updates since July and now I've got to try to catch up.
In addition to beginning work on the 5000, I also acquired new project. Back in October 2014, I purchased a set of Walthers North Shore ends on a whim. I had no plans for them and figured they might be useful down the road for trading or something. Later I was able to acquire a Walthers arched roof and mats. Again, purchased them only because they were available and decently inexpensive. (It should be obvious where this is going.) A few months ago I found a pair of Walthers “interurban sides” that were appropriate for a North Shore car. My new project is to assemble and complete this Walther’s North Shore kit. The car sides (specifically the window arrangement) put this car in the high 700s. I haven’t decided whether or not this car will be powered or even if it will be part of the Skokie Valley or Shore Line trains. It’s a low priority project; something for the backburner. In an email blast a while back, I saw a picture of a North Shore car built from a Walthers kit on the Salt Creek Lines. I’ve forgotten who built it, but it looked superb and betrayed nothing of its rather average beginnings. With the right amount of effort, I have high hopes that my planned car will look as good.
I've also done some 3D modeling. I went back and decided on a shape for the arches atop the support columns under the viaduct. I settled on useing a circle to create the curve of the arch although the shape of the actual arch is closer to a vertically squashed semicircle. The idea here is to make a mold of a 3D printed master since I’ll need fifteen middle columns and six end columns for the viaduct. I am yet to determine a method of actually doing this and I’ve also yet to select a material.
Circular arches. The green is simply a marker for how high the curb/sidewalks need to be and is not part of the model.
Once a suitable interior shape was developed to make the structure hollow (done to keep costs low[er]) I had it uploaded to Shapeways and printed. As soon as this went through, I suddenly realized a miraculously simple way of producing the "squashed semicircle" shape for the arches that I wanted. All that's required is drawing a circle and then rescaling it vertically, but not horizontally. The result is an oval.
"Squashed" arches. The difference is subtle, but the arches are a much closer match.
Meanwhile, the original design was printed and shipped out. The results were... less than optimal.
Looks okay so far.
Oh. That's not right.
Not sure where the surface stuff came from, but that should be easily sanded off.
It's difficult to see, but the piece is actually slightly curled.
I'm actually not too worried about it since the arches need to be redone anyway.
