I am new to modelling, but not new to being creative. My background, as a young lad, was diesel mechanic, welder, and avionics (RAAF). Past 20 years has been in counselling (no hand skills required). Then, out of the blue, I got roped into, by the local maritime museum, to convert an antiquated lift-span bridge console to operate a model bridge. Then I discovered that they had no model bridge and nobody to build one. Then I found out that the museum is totally run by volunteers. So I end up volunteering to build a model bridge which can be operated by the real bridge's original console (1964-1995), and have the bridge set in a diorama display of 2400 x 1200 mm (8 x 4 feet). Yes, I have to build the diorama too. I have been doing this for several months now. I am still a long way from completion. My plan here is to post photos of progress by piecemeal. Both the console and bridge lack available schematic diagrams and drawn plans. So the whole modelling aspect will have to be scratch-built. As a result, I had to extrapolate the bridge measurements from numerous photographs, reverse engineer the console, and figure out how to operate the bridge. The current bridge operator was not allowed to tell how to operate the bridge, but was able to tell me what each switch did. From this information it took me a while to figure out the operating sequence. It is not a simply matter of raising and lowering the lift-span. There is much to consider in terms of safety, and in controlling the foot, road, and vessel traffic even before raising the bridge. Anyway, the first few months was spent in compiling the information needed. Then draw up plans (bridge) and schematic diagrams (electronics) for myself to follow. Actually I still have some unfinished problems to solve. The whole bridge fits nicely within the 8 foot width using a 1/72 scale. Here is a photo of the actual bridge: The console as it arrived at the museum: Proposed display layout: Yes, there will be a model boat traversing under the raised bridge-span. It is hoped that the museum display will be interactive by the visitors (mature or not). Meaning, that the display operations need to be, as far as possible, child-proof. The last thing the museum wants is someone purposefully lowering the bridge on the traversing boat . Or any other possible out-of-sequence operations. This has become a major headache for me. Finally, as an introduction, the museum is a non-profit organisation, so it has limited funding. My task then is to build this display as cheap, yet in good quality, as possible. So please excuse my choices of materials to do the task. Both the museum curator and president as given my free rein to do this project, which is great, because I work best without a boss. Though this project seemed daunting to me, I had also found it very satisfying to see it progress along. Hope you will also enjoy watching this work in progress.
