CAN39-P – Coehorn Mortar, full scale, 3″ bore with Powder Chamber, 75#, 13-1/2″ long.
The Coehorn Mortar has always been popular here at Hern Iron Works. The original period pieces had a larger bore with a reduced powder chamber; Over the years we’ve been getting requests and inquiries as to a powder chamber in any of our mortars. I gave it some thought and actually came up with a reasonably inexpensive method to modify our cast in place liners to be able to now offer the Coehorn Mortar with a seriously overbuilt powder chamber on our 3″ Coehorn. See my early production drawing for liner details.
This has our standard DOM liner with 1/2″ wall thickness, and 3″ bore, with a 3″ O.D. x 1-3/4″ I.D. breach plug machine fit and welded in place. Your dreams are now realized and cast in this new offering!!

The shot that opened the Civil War was fired from a coehorn mortar. The Coehorn Mortar was a very useful piece, for it was developed in the 16th century, and there were still a few in use in British colonial garrisons in the 1920’s. The 12 pounder model of 1841 was mounted on on a simple bed and served by a crew of four. It fired a standard 12-pounder shell to a maximum of 1200 yards.
Hern Cannon and mortar barrels, except the 8″ Siege Mortar and 8-3/4″ Bowling Ball Mortar , are made with Steel Liner Tubes with minimum 1/4″ wall thickness. and with welded breech plugs. For bores larger than 2 1/4″, we use 1/2″ Wall Drawn-over-Mandrel (DOM) tubing.
