My gun carriages are so small, being 12mm long. 1.3mm wide brass strips were formed, cut and blackened to make caps. However, they still look to thick. Like everything in scratch building, you have to think outside the box, and get innovative. The next ones will be made with black paper that is about as heavy as 20 lb. printer paper. When coated with Krylon Satin Finish, they should last. These parts are going to be tiny!
