In all the years of shooting cannons i had always had access to antique sights or optics from surplus stores. Today i decided to attempt a vernier sight for my new Puckle gun, which i have written about on this board. I have recently seen a number of early iron sights and have decided to build a few variations and reproductions of such sights. Here is the first.
This is an offset post sight that will have elevation and incremental windage adjustments by means of screws. The sight is to be mounted on the side of the receiver block of the barrel. Near the trunnions. I like to scavenge for material so i start with a length of 1 inch diameter dom steel tube with .25 inch wall. Next is a long eye bolt, a screw and some brass bar stock. I am not yet doing CAD, so i start with a sketch and gather my material.
the sight aperture will be a flat blade soldered to a barrel nut that i made. This gets mounted in a tube with a slot. A screw is run through the barrel nut. A brass knob locks the scew in the tube. Turning the knob adjusts the windage. The tube that carries all this is welded to the threaded rod, previously an eye bolt. This rod will have keyway cut in it to ensure alignment. A knurled brass nut adjusts for elevation. Here are some pictures:
