I made the hardware myself out of 2 1/2" x 1/4" flat stock and 1/2" hot rolled round stock. I used pictures of Herns hardware as a guide. I bought the square nuts but came close to making them myself as our little hardware store wanted a $1.49 each. The base dimensions are 28 1/4"x 14 1/4"x 8 1/2" high. It should have been 9 1/4" high but I didn't like the look. I found these dimensions on the N-SSA artillery forum. These are for a 12 pounder. The 24 pounders is bigger all the way around. I found some plans on GBO but these would have been to small for my barrel, it would of hung way over the front or had to been set back far enough that it could flip over backwards, DD warned me or someone else about this in another post.

Default We couldn't wait...

I was going to wait for green grass to shoot my new mortar, but a little grass showing through the last of the snow will have to do. I had my step son here for a camera man and to do the magic of youtube. I'm not quite sure of which shot is which but we started with 100gr of 1F and a baseball, then 150gr and a dog food can full of cement. The one with the newspaper wadding was 500gr of 1F. I'll try flour blanks next time as we won't have snow cover.

Nice. Your mortar looks great. You did a good job building that. Looks really nice. Have you given it a name yet

Your newspaper blank video is perfect example we say don't use newspaper. The newspaper came out as a burning projectile. I am pointing this so others can see. Do that in the summer time and you will have a fire.

You will never get much of report from a mortar, but flour will help. You can set the mortar close to a fence or wall so the mortar is shooting parallel to the line of the wall. Have your audience on the opposite side of wall. The concussion will bounce of the wall.

Also have your camera man turn his camera sideways and shoot landscape format you will catch more action.

Now that I tossed all these instructions out, get back out and shoot some more. We are never satisfied, we need more smoke and fire pictures.

Great job, and thanks for sharing the videos. You did very good work all around it looks like.


Looks Fun. I really need to get a Mortar done. It is on the list of addictions to come.

Yes DD, by the time I carried the newspaper wadding to the fire pit it was fully on fire. Not much to burn here now but in August that would be a different story. The report is nice, enough to send my dog under the bed but not enough to have the neighbors sticking their heads out the door. The next time I shoot it I'm going out to the farm where I can stretch it's legs a little. Oh, by the way, yes his name is "Ole Hickory", if he'd had it in 1814 he'd have used it. I am officially an addict is there a 12 step program for cannoneers ?

Addiction, nonsense. I am not addicted. I am very diverse in my interests. See that cardboard box lower left, that's the model rocket stuff I do with the grand daughter.

DD,
You clearly have a problem.
Your books are crooked.
Oh, so are mine!

Wow, is the only word that comes to mind. Beautiful collections. I'm merely hooked I see, not addicted.

northwoodneil,


Just so there is no confusion, every single gun barrel you see in my picture is made out of wood on my lathe. The only exception is the fabulous little Brooks 24 pounder you see in the left of the picture on my desk.
