When I was writing about the explorations going on for Civil War artifacts in Charleston Harbor, SC, one of the objectives was to locate frame torpedoes.
I did some research on them and did not turn up a lot.
They were set on a wooden frame, often equipped with acid fuses. The simplest ones were artillery shells weighing up to 400 pounds with 30 pounds of powder. Twenty-seven Union vessels were sunk by Confederate torpedoes when they ran into them. How many were sunk by frame torpedoes was not mentioned.
There is a nice picture atwww.thehunley.com
The wooden frame was set up at an angle with five shells/torpedoes at the top.
