Updated 8/25/2018:
I decided it was a good time to try test fitting the bridge onto the layout.
The bridge sections are held together with screws whose head accommodate 3/32” hex keys. I have an entire storage bin full of old allen wrenches. Do you think I had one that fit? So it was time for a detour to Harbor Freight for that and for an LED headlamp (my old battery one corroded).
To support the bridge on the piers, I realized that I needed all my bridge shoes. For Panhandle 1.0 (when the bridge was smaller), I only needed 4 bridge shoes. But with the prototypical approaches in place, that number became 18. That turns out to be 2 at the western abutment, 4 at the pocket-pier, 2 at the mid-river span, 2 at the other mid-river span, 4 at the pocket pier, 2 at the “shorty” pier, and finally 2 at the eastern abutment (stone arch). I had the parts cut awhile ago, but never put them together. Here are some of them in the paint booth.
And here they all are after getting a coat of flat black.
More when I know it.
