Finally have some progress on the HBG gun carriages and gun positions. The barrels have been cast in Alumlite. See the previous post or my flickr page for the details of the mould. Not the best or highest tech mould making, but I got a couple guns out of it to use. The brown spots are Tichy Train Group rivets, drilled and glued into place. I have a little do-dad for each gun for the elevating mechanism.
When I was building the carriages I made a flat out of art board to set the various elevations of the platform. The pivot was the highest and there are two steps for the runners and the wheels. Here I began work on a gun position. There will be three gun platforms, with sand/turf hills between each rather like the land wall at Fort Fisher.
