9 inch Dahlgren Shell Gun
The 9 inch Dahlgren Shell Gun was designed by Admiral John A. Dahlgren, of The Federal Navy. In addition to the 9 inch Shell Gun, Admiral Dahlgren designed a complete system of artillery for naval use. These Dahlgren Guns of various sizes, were mounted on several different types of carriages. They were used both, on land and on board ships during the Cicil War between the North and the South.
I scaled down my #2 plans by half, to build this tiny 9" Dahlgren shell gun with a barrel measuring 2 1/2" in length.
That is the cross-slide of my lathe that it is sitting on.
