[dan610324]

This is the best I can offer on Mallet's mortar... Not enough, I guess, for a project - I'll see what else there is around.

     Dan,  I don't know if you remember our thread on building a 1.720" bore Mallet's mortar or not, but it might help you visualize some of the parts and shapes of this beast of mortars.  There is a conflict between the configuration of the breech presented in Starr 2011's diagrams and the photo we found of the actual mortar as it exists today at Fort Nelson, Portsmouth, UK.  We are very appreciative that he posted that set.  You don't see too many prototype drawings of historical ordnance.  Perhaps the lack of conformity can be explained by a drawing, yet to be located.  There are two photos showing a side view that illustrates a breech that protrudes below the heavy base plate.  We located one of those which we posted below.  Despite it's diminutive size, it clearly displays the structural elements of Mallet's Mortar of 1857.  Only No. 2, at fort Nelson, exists today.  Some "all rights reserved" photos in Flicker, et al show the same breech protrusion, but we can't use those legally, of course. 

     Good luck Dan.  This is the link to our old "build thread":   http://www.gboreloaded.com/forums/index.php/topic,125169.0.html

And while really small, this next one has the best view of the different parts that I've found:

One more drawing of the final version of Mallet's mortar, this one from 1867. The first drawing I posted (as the ever vigilant Mike and Tracy noticed) is Mallet's original design - dated in the lower right corner 1854 - Mallet made many changes before the mortars were proved in 1857.

The 1867 drawing shows the innards of the "carriage". I don't know how these components were meant to work.

The written description of how it was constructed and how it comes to pieces for transport exists on several websites, if you would like a summary let me know.

Peter Smethurst the Curator Emeritus of the Royal Armouries Leeds made a detailed model of the Mallet Mortar several years ago.  He sent me a drawing that showed all the segements of the mortar.  That was a couple of computers ago and I o no longer have the pictures...but I did send him and email and asked him if he still had the drawing.

Dan,
       As part of my WORLD CANNON VIEWING TOUR I will be visiting Fort Nelson and Woolwich Firepower Museum in Mid September 2011.  If you can wait til then I will be doing a 'walk around' of Mallets Mortar and can make enquiries about drawings and designs.  The photos I take will be published here if you like or I can send them to you via email.

regards

I now have the detailed drawing in 1:24 scale.  I am currently working on permission to post them.

If you are looking for drawings you should contact  Royal Armouries, Leeds, www.armouries.org.uk, that is the source of the drawing I have

I also have a PDF File with an article about the mortar I can share.  Send me a PM with your email address so I can forward it to you.

     Full Size ??        This link brings you to a version of the drawing that is even smaller than the one you posted where the lines were visible, but the dimensions were not.  Do you have a drawing where the dimensions are visible ?   Thank you for obtaining and sharing what is shown in the drawing you displayed.  It's very interesting to know the shapes of the layered rings that form the tube with their gas-sealing right angles, etc.

Thanks,   Mike & Tracy

Try again...now

  Thanks DD.  Got it.  You can see the numbers at size 8.5 X 11 or take a copy to Kinkos and get a 'A' size drawing, size HUGE and see them from 10 feet.  Very nice!

The PDF has a brief history of the mortar and the story of its restoration.
