A Victorian-like steampunk blunderbuss rifle is illustrated in this mod which can be seen being held by the guy in the images below. The materials to be used will include brass stuff, wooden banister, table leg, wooden doweling, gorilla glue or equivalent, snowpaints, railing, spraypaint, brown stain, jigsaw or equivalent, drill, tinsnips, gloves, screwdrivers, old phonebook or large chunk of wood and other tools.
To start the design, wooden banister rails is cut off to the desired shape, sanded, and spray painted with gold/brass color as shown below. The boiler is supported using a bag of old parts including several towel rack supports which consist of two pieces with a screw holding them together on the bottom. It can be affixed to the wall invisibly by having a plate on the bottom and held by a tiny set-screw. A threaded shaft on the inside holding the cylindrical parts together with a nut on the end supports the brass candlesticks in the image below.
The basic part from the candlestick with the brass bucket was repeated and a hole in the end of the bucket was drilled. A bit of threaded rod from the chandelier was mounted with some washers to the hole in the support. The two supports and their brass parts can be mounted on the shaft of the gun. A butt shown below is needed for the barrel of the gun which was made from a table leg. It was drilled and stained darker while a couple of dowels were applied. Some brass tinplate brackets were used and drilled into an old phonebook.
To create the trigger, a swirl from the chandelier and an old coat hook were used as shown below. Using the existing threaded rod, a wooden dowel, and glue, the swirl was cut off and mounted like the butt. The next image shows the blunderbuss which comprise of an old lamp bottom and another towel rack support. The towel support was used as the ray gun as the base was inverted after taking the lamp apart. A hole drilled into the barrel has the glued haft from the lamp.
A lot of swirls, tubing, hardware nuts, and threads can be used since there are 12 arms available. If the tube is straighter, the wire comes out of the tubing easier. The tubing can be bent without folding it and snowpaints are used to pad the railing outside. The tube is put at the beginning and bends a little over the rail. The hole where the electrical cord was in the bottom of the lamp base, the swirls conveniently fit right when mounted. It was bolted right on with a nut as the existing thread from the arm attachment is used.
For more grip, some screws were put into the holes of the door pull and left them sticking out. The butt flourish shown below went with the finial from some sort of cupboard door handle pull since the butt of the gun needed something. For the alternate ending, an alternative boiler design used the second pair of candlesticks and just the burner of a cheap oil lamp with glass chimney supports just folded over the end to hold it on as shown below.
