Conventional fuse. The tube is solid steel, no breech plug, turned and bored out of an old Mack truck axle. Now working on an idea I have for a gunner's quadrant so I have at least some quantifiable data to predict POI. Main use: shooting at crab pot buoys out on the Chesapeake Bay. Might use it for deer this fall, dunno.
Off your deck, or are you planning to mount it on the foredeck of a boat?
In IIRC, Forester’s
Commodore Hornblower, there’s a fair bit about the gunboats they used to shell the enemy. Cutting fuse to time the explosion of the shell, measuring out the powder for range, and using hawsers to swing the boat into alignment are gone into in some detail. Very interesting stuff.
