Steampunk Holmes Technology: The Black Widow's Gatling Gun

As I wrote in the blog entry "Steampunk Holmes Technology: Mechanical Drawings" one of the Steampunk Holmes book enhancements is to provide more information about the various gadgets that Holmes, Watson and others use or encounter through out the story. Above is the mechanical-like drawing of the Black Widow which runs on a H2O2 steam engine and sports a Gatling gun under the hood of the side car.

I did a little research on the design of steam engines and ended up combining two designs available at the time into one. The Black Widow uses a two cylinder (or compound) engine for quick acceleration and power and a steam turbine as a second stage for sustained speed and long distances.

The Gatling gun fires 300 rounds per minute. At that time (1885) Gatling guns could fire much faster but there would be a problem with storing ammunition, so I chose a slower rate of fire but instead of being driven by a hand crank, as was common, the eight barrels turn and fire using the kick-back for the previous round (aka Recoil-Operated). The ammunition is a smaller caliber .303 Lee-Metford bullet of lead encased (jacketed) in copper to improve accuracy (lead tends to warp its shape when fired distorting accuracy).

I don't know if most readers will appreciate all the work we put into these designs, but I know we are having a total blast developing the story, gadgets and art work. Stay tuned as we are currently working on the design of Captain Nemo's Nautilus!
