Boulevard Streetlamp / Line Poles

Attempting To Build A Working Combination Streetlamp / Linepole!

 Well here it is, a fresh 3D print from i.Materialize. But this is only the beginning. This print can't be used on the layout because one: I believe the "Prime Gray" material would be too brittle for the tensions of the overhead, and two: I want these lamps to light up. So this fella will be the "master". A rubber mold will be made from this print that all the other lamps will be cast from. But I digress...

As detailed in a previous post, each of the 6 streets feature distinct line poles. The 1920s era street pictured above is to have Boulevard streetlamps that double as line poles. Right now I have temporary wooden poles that are planted beyond the sidewalks until the streetlamp locations and hole size to be drilled in the sidewalks are determined. But for now, the temp poles are fouling where the building are going to be placed. So these lamps have become the priority project.

 San Diego didn't have these kind of poles but our neighbor to the North was kind of fond of them. The Pacific Electric sported these kind of poles in a few cities. This one was in Long Beach.

The San Diego Electric Railway attached their overhead directly to the adjacent buildings, thus clearing the streets of unsightly linepoles. But I don't want to attempt to deal with attaching the overhead of my layout to model buildings. So I thought I would try modeling these Boulevard Lamp Post / Line Poles (I really wish I knew what these were called!) instead. Besides, they look cool! 

Years ago I fabricated a couple of these lampposts out of brass. But they were very difficult to build and highly time consuming. There are so many small parts that trying to solder one part melts the joints of the other parts. Frustrating. So the project languished until either my soldering skills improved, or I thought of a better way of building these, or some sort of miracle happened.

Well wouldn't you know? A miracle happened! In the form of 3D Printing! Building this lamp with a 3D program is WAY easier than building it with brass. And a lot faster. I modeled this with 3DS Max.

My lamp design is a hybrid of San Diego style Boulevard steetlamps and the Los Angeles linepole streetlamps.

I'm pleased with how the print turned out. The lamp had to be designed with the 1mm minimum thicknesses required for 3D Printing. But I believe the level of detail is just right for HO scale.

Now comes making a silicone mold from this lamp. This will be a new adventure for me. Yes sir! This will be a new adventure!

Wonderful World of Color

Painting the Streets and Sidewalks

 I've been staring at plywood and plaster for so long that even the new concrete coloring looks exciting!

 I grabbed some buildings and posed this little scene. Two of the streets on the layout represent the pre-paved era of streets. So they were painted Floquil Earth.

 But for the most part the rest of the layout is painted Floquil Concrete. And of course Floquil came out with "Aged Concrete" right after I painted it! But it doesn't really matter anyway because...

Another case of "if I were to do it again". Because if I were to do it again, I would have used Durhams Water Putty tinted with concrete coloring. In the photo above the effects of track cleaning and chipping on painted plaster can be seen. Bright white plaster peaking through. Tinted water putty would fair much better.
You guys are so lucky to be learning from my mistakes. Yes sir! Your so lucky!

Paving the Way

Pouring the Streets and Sidewalks. 

Extensive testing of the track is essential before its covered with street paving. Especially that intersection. Making revisions to the track would be most difficult when its buried in plaster. Plus its fun to just run the cars around too!

It seems logical to me to pour the sidewalks first. I used angle stock that was the thickness I wanted the sidewalks to be. Where the sidewalks curve at the corners I cut slots in the angle stock so that it could bend (sorry about the dark photo). Then the angle stock is spiked down to create a trough to pour the plaster into. 

I used lightweight hydrocal, but if I was to do it again, I would use Durhams water putty. 

Originally designed for DC operation, the track is cut into electrical blocks. In the photo above you can see where the wires come up from under the layout and soldered onto each rail of each block. That also has to be tested for electrical continuity before being buried in the plaster.

 Once the sidewalks were in and the track passed inspection, I started in on the streets. Stripwood equal to the height of the rails were glued against the sidewalks (where the gutter would be). Then plaster could be be poured in between. The stripwood and rail would be used as a guide for a paint scraper to smooth out the plaster. I stuffed thick string into the flangeways to keep the plaster out, but I think I could have just masked if off with tape.

Interestingly, all the spikes rusted and soaked through the plaster. But I don't think the strength of the spikes were compromised. Besides, everything is now held firmly in place by the plaster. Derailments should be nonexistent since the whole layout is basically a rerailer!

Finally I sanded down the all the streets and sidewalks with a block sander to make it all nice and smooth. I don't want any pour marks showing. I also scribed expansion joints in the sidewalks before the plaster got too hard.

I can't get over how different the layout looks now. It's all looks so neat and tidy. Now I have got to get some paint on it. Right now it looks like a winter wonderland. Yes sir! It looks like a downright winter wonderland!
