This blog will detail the construction and development of Wrightsville Port -an imaginary N Scale waterfront layout. Wrightsville port is a small harbor on the Atlantic in North Carolina. The model depicts 1960-1970 era and will feature the diesel motive powers and the "New Age" system of inter-modal transportation.

Restoring Bascule back to Glory!
Well, by the end of last vacation, I decided to repair it and put it back on the layout since I was missing it too much, and without it the port had lost its character significantly!
First thing, fixing the counterweight truss. The problem was that it was so badly screwed up (basically one side totally broken) it wouldn't have been possible to just glue the light wood structure and bring it back to it's original strength. So I decided to drill small holes and use wire support along with superglue to hold the structure. Also, I repaired the links:
Then the leaf, and most importantly managing the electrical connections. Previously it was a press on touch connection using copper plates at the end of the bridge - so basically when the bridge used to be lifted there was no connection to the rails. The main reason was that I didn't want to run wires all along to the movable part and solder it in a very visible and difficult to access area. But given all the old alignments are now gone, I decided to solder those wires right away, because without proper alignment, having good electrical connection and reliability is impossible.
Then I had to link the leaf to the counterweight structure. So I redesigned the links and kept it simply one piece of styrene, secured tightly on the leaf using glue and pin.
Next step was to istall the bridge on the layout and run the wires down and connect to the block:
Still the misalignment was pretty concerning on the other side of the bridge where it meshes with the mainline. So I had make a chair and shoes to adjust the alignment:
Now the bridge does sit well, and brings back the old charm to the docks! :)
And after covering up the Screws, bolts and lever access holes:
Now some video to see how the train runs on the bridge :)
