I've made tons of progress on a Brass truss bridge I'm scratchbuilding I got cell phone pictures of it in various stages of construction that I can post this week. I've built the inner web members from 1/32" x 1/8" and 1/32 X 3/32" brass flats and GMM W and X bracing. The main chords are 1/32 X 3/16" flat bar with GMM 24" X bracing. All the gussets are sheared by hand out of .005 brass sheet I need to build the open trough floor next then apply Archer rivets. Also am working on adding a junkyard to my layout.
