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!!

This mortar looks great on the Base available on this site as a Hardware Kit and Plans for the Coehorn mortar bed.  You will not be disappointed with this historically accurate Kit & gun!  (Please note – Hardware Kit includes 2 pair of trail handles, do not buy a kit AND additional handles unnecessarily.)

Cannon is boxed and packaged for UPS shipment to the US of A — Included with the price shown.

I generally keep one or more on hand as these are quite popular; sometimes we do run out of stock but will let you know if there will be a delay in fulfilling your order! Aug.’19 – 4 plus, on hand

 

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.
