Douglas, I enjoyed your visit today and I'm looking forward to seeing your bowling ball mortar when completed. Looks like it will be an awesome piece of ordinance. Dom

Dom,

It was a pleasure finally get to meet you and thanks for the guided tour of Glicks...the breech plug should be plenty strong made of 4140!!! And thanks again for lunch.

Family Reunion. No. 14 got together with No.24 and visited with their cousin Dom Krupp.

The adults were very protective of the little one and were constantly reminding him not to load himself with any blanks in order to scare the cat. They had a nice light lunch which started with Potato Soup and then the Pork Belly and Sausages were served with Sauerkraut, Red Cabbage, Mash Potatoes and Dumplings. While they were eating the cat went under the massive oak dining room table and scratched the wee one's knees in retaliation!

Love that photo. Thanks for posting, guys.

It was a special get together in Easton, PA. (#12 and #24). No pictures, we were having too much fun. Ahhh the smell of black powder.

This after noon we did some test firing of fire cracker and bottle rockets.

The firing of the firecrackers went as advertised and we were even able to double shot using two firecrackers. We got aerial burst 25 to 30 yards out...

Firecracker

We tested three types of bottle rockets; two paper tube type and one plastic tube type. The two paper tube type had some serious flight issue fly all over the place and bursting, and that includes doing a 180 and coming back at us.

Bottle Rocket

Listen to the video and you will hear the longer duration between shot and detonation of the bottle rocket down range.

Thanks for trying it out, DD. Doubled Shotted??? Think of the pressure spike potential, Douglas.

Those bottle rocket trajectories sound like some of our WWII torpedoes! Nice clips. Did you cut the 'tail' off?

We pulled the stick of the paper tubes left the fuse in. We pulled the fuse out of the Dixie whistlers plastic tubes.

Actually we double shotted Ernie's break open Firecraker Cannon.

No 24 stopped in at Southpaws to visit today.

No. 24 also stopped in to visit his brothers No. 8 and No. 9 but they have become elitist unfired mint in the box types and wouldn't come out to visit.

Ernie , "A ship in the harbor is safe ,but that's not what ships where built to do ........."

On the other hand ....... If you have free licence with DD's #24 to "use it" when the mood ,as it is a mood thing , I watched Kelly's Hero's

tonight and Sargent Odd Ball reminded me of the mood thing.

So there's that too .

....your call ,

Ernie, just as lighter-than-air, ships "slip the surly bonds of earth" when the ropes are let go, surely you can carve one of those two Krupps out until it "slips the surly bonds of tape" and belches forth great quantities of black powder smoke?

You look like the sort of guy who can whittle a whistle out of a Moose Maple twig in less than 15 minutes, certainly you can cut packing tape!

Well , If I open"The Boxes" the wife will know what's in them !

They will make their big break for Freedom on the 4th of July .

DD and I are planning a bang up day of mortors , cannons , explosive devices .

Stay tuned .................

PS: less than 5 minutes with a sharp knife and Golden willow for a good whistle .

O.K. Ernie, the 4th it is! Plenty of pics please. And I thought I was the only one who could put birthday gifts aside for months without opening them! Golden Willow here, Moose Maple in upstate N.Y. I was pretty good at making them too!

The picture above is a frame freeze from this video.

Is that one of Ernie's "released" Krupp Howitzers or yours, Douglas? And.......How much powder are you using in that gun? The chamber only holds about 5 grains; are you muzzle loading more on top of that?? Quite a flash in that frame extract! That cracker trajectory looks like the one most of my golf balls followed 100 years ago when I still played flogball!

Mike wants to build a larger Krupp Gun with a longer tube and a 1" to 1.5" bore, rifled, of course. Time will tell.

That No. 24 and a standard full chamber of FFFg and nothing more. It was shot by using a flashlight on the cannon to aim in the camera. Turning on the video, turning of the light and firing the gun. Then I went back a did a frame grab for the still shot.

Ernie does have one gun unpacked, the other is still in the box.

Ernie uses a propane torch for ignition so we don't get as a dramatic a shot, when firing his guns.

A one inch Krupp would be cool!

Will it be a breechloader with a "rotating/sliding cylindrical breechblock"?

Colin, Welcome to the United States! You look like you are dressed for a Victorian Rifle Contest with that pith helmet. Sounds Like Douglas has been showing you the 'best of the west'.

We think so too, but we have made so many 1" guns maybe a 1.5" bore would be interesting to make. It would be roughly a one-pounder plus. Just a little bigger than a 37mm. We would have to make driving bands out of copper pipe pieces parted off on the lathe and then split. That way they could be snapped into a groove near the base of the bolt.

Dom, I talked to Mike about this and he said, "We will go with an authentic, sliding, wedge-shaped breech block, screw activated from the left side just like the original. We could use our shaper which is a 9", but EDM sounds better because you can produce the block and the recess for it in the breech at the same time." Stock a little thicker than final breech dims. would be used to allow for a near perfect, tight fit as the block bottoms out at the end of the gap made by the EDM kerf. Probably a short case would provide obturation just like the Kraut, bag-guns had. Maybe this project and making liners and going shooting with our finished, 7" Brooke will keep us busy for a year before starting the 1/6 Scale, 150 Pdr. Armstrong Seacoast Rifle, M1864.

Well the 4th came and went :<(
On July 2nd # 9 after much struggle and a few choice words begrudingly flung loose it's many layers of bondage to emerge wonderfully proud of it's new found freedom . What a Beauty .

# 8 on the other hand was a bit shy and afraid of what the future would hold . After the months of bondage it has become timid and unsure of it's future . Today the rest of the "Gang" gather'd to offer words of solace and reassurance .
as of this moment # 8 remains behind the "8 Ball "

Mike & Tracy,

As always, I'm looking forward to seeing this being built. You sure know how to pick interesting one of a kind projects.

Gee Ernie, hope you had shades for that little Krupp when you finally exposed him to the big, bright Montana sky!

Dominick, your recent posting of that Russian seacoast artillery gave us a glimpse of the Breech Block Retracting Screw tracks that we must machine into the back of the Breech Block Recess in order to haul the heavier Breech Block in and out of the future 1.5" to 2.0" Krupp rifled projectile gun. Thank you! Never have seen those before.

Ref. the pic below:

dominick · « **Reply #776 on:** July 22, 2011, 12:31:43 PM »

You're welcome. That's a model 1867 so I'm quessing that it was probably a direct close copy of the model 1866 that you built. A. Krupp may have sold them the design.
