This is a 20" diameter wheeled mortar carriage I built for a local friend of mine. The barrel he got from me 3 years ago is a 4.62" Federal Coehorn replica and weighs 80 pounds.

Any idea on how much it weighs? And how thick is the axle? Just curious.

I think the carriage weighs about 90 lbs and the axle is 3/4" diameter. He fired the mortar several times in the past. A candle pin bowling ball fits. So does 4" pvc filled with concrete.

Nice set up!

From the looks of it if on the wheeled carrage fully depressed
it could stand in for a howitzer.....

If the adjuster bracket was lower it could be fired from level. I think the recoil would be vicious. The trail is too light and it would flip forward if the barrel was leveled. It's towed with the barrel flipped over backwards against the small stand on the trail.

How long would the axle last if fired at high angle? Not long I think.

DD, it appears from the pictures that the mortar is intended to be fired sans wheels only. ANY angle with wheels would make it a poor candidate for keeping it in battery or to stand near when discharged.

Yes correct....

Bend that axle up like a pretzel.

It's made from 3/4" solid round. Would need a much larger carriage if fired with wheels on.

It could be measured in milliseconds.

Probably about as long as the trunnions did on the first model King Howitzers.

You've got a lot of firsts here, Dom, and you did it again; you're the first to use the British travelling mortar carriage as the inspiration for producing your own version in steel, and it looks both fine and functional!

Here's a video of the mortar in action.

I like your tandem towed setup very cool . With a little modification that could be pulled behind a truck ( I am thinking slow speed back roads) Robin

Neat little slide show/video. Somewhere in there is a calendar shot.

Blank load? Falling tree branches? Is there a lesson here?

Dom, good show, nicely done.

RocklockI · « **Reply #25 on:** March 02, 2011, 06:05:44 AM »

Here is one I came across a couple days ago . I really like it as it looks boarderline medieval too me .

Gary

I am considering using this as a model to make the carriage for my bronze caronade style howitzer . It looks as though it will acomadate the underlug style 'trunion' very well .

In the wax .

Bronze !

Notice poor surface finish on the bronze

.... right now this is an issue as it takes alot of time to polish them out in bronze

, the problem is because of poor surface preperation as wax.

That issue will be resolved on the next piece , which will be another one of these ...

Gary.
I too think that barrel would look great on that carriage. Do you have more in progress pictures of that barrel?

No not yet ,I worked on it today and yesterday . I have a call in for Tracy to take a couple of shots and send them to me ,then I will post them in the "New Bronze Thread" .

It is looking good though , The center section will be done by hand .......

I guess I told you at least 29 times that its easier to clean up the wax before casting than to clean up the cast bronze
