I'm working on some modern covered hopper kits and I want to add some details, but I don't know what sizes of wire or parts to use for things like stirrups, grab irons, ladder rungs, hand brake chains, brake piping, and so on. Advice? Thanks!
I've a couple of Detail Associates packages sitting here. #2503 which is .010, on the package is says represents 1/2 inch diameter; #2505 .015 which is stated as 1" diameter.
Model Railroader had an article which listed the corresponding wire sizes for the three major scales. I started with that and created a spreadsheet graph that also included drill sizes and dimensional lumber, and put it up on my workspace. It comes in handy. As for grabs, I find it hard to make the standard side ladder grabs consistent. It's best to buy those in bulk. Get a good pair of small wire cutters, and have fun. Filing the ends of your cuts helps it fit. Mark
