Here's today's work. Bridge two is almost complete except for the thin cross bracing and rivet decals. I've ordered the railing stanchions. When bridge 2 is finished I'll paint both of them and then install the track, walkway and railing.
As I moved up the learning curve, I was able to fit the main rail supports between the cross beams much more precisely. I only needed to use CA on two of them. By cutting them just a tad long and using the True Sander to bring them to exact length, they all nested in nicely and were welded with plastic solvent.
