Hello to all. I am in the early stages of scratch building a pin connected wooden Howe Truss Bridge, and I've run into some detailing questions. First off, this is not going to be a prototypically perfect replica, but I definitely want to include some nice detail on top of my horizontal cross beams. I am running into problems working out the tension rod fastening detail. My thought is to use .015 music wire for the tension rods, but the nut and thread detail top and bottom is difficult to model in N scale. I'd like it to look a bit like this, however I'm open to new ideas:
On my bridge, that plate would actually fasten to a beam spanning the width of the bridge, top and bottom, with 4 rods per beam. I've looked for miniature all thread, nuts, and washers, but the smaller they are, the more the cost. Any suggestions, tips, or relevant pics would be greatly appreciated.
