Lattice girder development

Work is progressing with the lattice  truss bridges. My friend, Clark C., who’s helping me with the bridge design and fabrication is doing a fantastic job. I really appreciate his talent.

We decided the best approach would be to design and laser the girder structures for the two spans first so that I can put them in place to get the track operating. Clark has designed the bridge so that the side trusses can be fabricated separately and then attached to the girders at a later time.

Of course, once one of the trusses is complete to our satisfaction, the other three will be easy to create.

I’m very excited about these bridges because they will be my signature scene on the layout. Lattice truss bridges are not modeled very often, so they will be a truly unique feature.

First switch stand installed

I finally installed my first G-scale switch stand on one of the Milan runaround turnouts.

I painted the targets red and green along with adding some rust on the four bolts that hold the stand in place. The points are thrown with a very simple throw arm designed and fabricated by my friend, John Klocker. As you can see in the photo below, the throw arm has several different entry points for the guide wire. In addition, I reinforced both the guide wire and vertical throw wire with aluminum tubing to help stiffen both wires.

The switch stands will add a nice, realistic touch when switching.


 

Protection for G-scale switch stands

I will be using G-scale switch stands to throw each turnout’s points.

One issue I had to resolve was how to protect each stand from being damaged by a wayward arm or elbow. The solution I settled on was to use bronze colored sprung door stops. If an operator gets too close from either side, the door stops should do a good job or getting their attention to avoid snapping off a stand.
