Doing stuff again.

[Chris333]

So far this layout has been one sided. The "other" side will be more rural with a farm house and a creek. I wanted a lacey looking bridge that looked old. I found these 2 photos (well I reversed them to fit my scene better)



I only have 5" of a straight for the bridge. When I cropped the photo to be 1.5" from the rail to the water I ended up with this.


No idea is it to true scale, but then again I have no idea what that would be anyways.

Any one know what you would call this type of bridge on the right?  I need to do more research and find a close up with rivet detail.

I'd call it a pin-connected deck truss bridge

[Chris333]

Well I didn't want to spend a bunch of time on this... I asked AI to enhance the photos and it looked like gussets at the joints. So I quickly whipped this up.




Gonna print the concrete abutments also, but texture them by hand afterwards.

[Chris333]

From pixels to molecules?





I have no idea why this bridge would be in 2 spans like it is, but there is one about a mile from my house that is the same way. 80' + 20' to cross a creek. I think way back then it was easier to just buy off the shelf bridges and drop them in place. And about 100' from the bridge by my house used to be this bridge made up of 3 spans:

one possible reason for a bridge like this is if the short span needed higher clearance than the long span - for example if the long span were over a creek, but the short span were over a road or railroad.

Asking for my future self...


Does anyone have N scale Bluford Shops corn in stock or for sale?  Prefer summer green, but will take what I can get.

Might be going to a shop next week that has a box or two last time I visited. I will PM if they are still there.


And on the bridge topic, some of the bigger steel firms would also sell premade bridge sections that could be stockpiled. So they may have just had an 80ft and a 20 ft on hand and decided it was cheaper to build a stone abutment than order/make a bespoke 100ft bridge.

From the picture, the pier is on the bank. There's definitely the possibility of a road along the river, although its hard to tell. Railroads will use deck girder bridges wherever possible, they're cheap.

So the next shiny object I spy is a Schoen Pressed Steel hopper with fishbelly sides.

Everything I read says they were gone by the 1920's.  But the PRR version was called a GL and from 1923-1935 they were rebuilt to a GLc

More rebuilds 1941-1946...   OK good enough for me     sounds like a green light.

[Chris333]

Now that the first car is printed I'm reading the GLc cars lasted till 1961, but were 33' versions of the car I built. My car is 29'. Oh well the show must go on.

[Chris333]

Ok so the hopper on top printed fine except for that big whoop down the side. I think it was because there was no opening under the car and suction. I re-did it without the hopper doors and that is on the bottom.



Printing the hopper bays now and after that the goofy trucks.

And the bridge is installed. Have to weather the abutments because there is no way to install them later.

Very cool.  What resin are you using?

[Chris333]

Anycubic DLP Craftsman resin.

[Scottl]

Thanks.

[Chris333]

All trucked up


The un-primed center section of the floor is added. Slot for 1/16" tungsten, but on this one there are a few other cubby holes for weight.

And those are the little top hats to hold the trucks on. This way I can tighten their screws tight and the trucks still swing. And I'm not pushing a pin into fragile resin.
