Interesting concept. Why not put a Mortar on a Howitzer carriage? Seems to work in the drawing. I like the way they made the wheels, too! BoomLover

     Dan,   We really love the shape of that chamber!  Now we can add egg-shaped or ovoid to the list which includes hemispherical, reduced-cylindrical, modified cylindrical, tapered, Gomer, conical and spherical.  I read once that the spherical shaped chamber was supposed to be best in that it produced the greatest pressure and, in those tests, the greatest range for the shot.  I bet the gunners DID NOT think good thoughts about it though, when they had to clean it!

We like the carriage,

     Point the tube at the mid-day sun.  Empty powder scoop into muzzle.  Hit the tube with a big wooden mallet vigorously 10 times!
You're done.  Now machining it back in those days would not have been fun at all !!

     Magnum Indeed !

Dan Forget cleaning how about swabing for the loose spark!


M&T that chamber would have been cored rather than machined.......

it must have been interesting polishing out the rough spots.......

John Muller, I think, posed the question in the 18th Century as to why artillerists didn't forget the mortar because of its difficulty in transport and just modify the howitzer carriages to allow greater elevation.  But his idea never caught on.

The submitted example may be a field expedient.  They may have needed a howitzer for a pressing engagement but only had mortar barrels available.

Maybe the recoil of a mortar or howitzer at extremely high angle was to hard on the field carriage.  I know that my 8 inch siege mortar bounces on the platform.  The ability of the carriage to recoil helped to lessen the shock of firing a cannon.

I believe it was Don Krag who was building the "standing mortar" which had a mortar-length barrel mounted at a steep elevation on a carriage similar to a field carriage.

Haven't seen that one lately, I wonder how it's coming along?

I'm sure they would have been breaking axles at a prodigious rate, especially with the large bore ones.  I would think you would have to remove the wheels and lay the piece on the ground to fire it as a mortar, maybe even digging out an area for the breech to be depressed into.  And then you would have to have something to lift with to get it back on the wheels.
