      You know DD, I wasn't quite sure if I had an answer to your question, so I decided to take a walk out through the sprawling Broomfield Cannon Manufactory this morning and ponder your question for a while.   I walked north along the side of our canal that roughly divides the works in half.  As I passed the idle finishing shops, I noticed a couple workmen whittling wooden bobbers for their next fishing trip.  I passed the boring mill shop and thought a little about those newfangled flashlights.  Passing the Forging Shop with it's silent 100 Ton Hammer, I mused about tipping the tube to dump the cap fragments out, but it wasn't until after I went beyond all the raw materials sheds, that I realized that I needed to talk to Sally, the best barge-hauling Mule we've ever had, so I crossed the little, high-arched canal bridge and headed out into the western pasture. I saw her at the far side with her head bobbing as she ate the lush, new Springtime grass.  As I approached, her head swung around and she nodded approval of this frosty morning visit.  I patted her flanks and whispered nonsense to her, and then, while kneading her big 'ole ears, I put your warranty question to her.  She shivered all over as I tickled her belly, and, with a series of nods and snorts, seemed to approve of the new method of Krupp clearing.  So, from the smartest critter at the cannon works, you have your answer.  If it's good enough for Sally, it's good enough for us!

I have a brother-in-law that makes fine Windsor Chairs ( http://www.windsorchairresources.com/sawyer.html ).  Makes 'em by hand.  Starts by walking through the woods, around the right side of the pond and picks each piece and type of wood for each application.  Carves by hand, steam bends and finishes in the original milk paint.

His warrenty is just as well thought through, but a little different.  (both are good)  He simply says, guarenteed for life - yours or mine.   ;D

Completely disassembled the barrel mechanisms today and was surprised how much crud I had missed with my earlier simple cleaning. From now on a full strip will be the order of the day after firing, no reason not to with your easy disassembly.

I havn't had any issuses with jamming caps I have been using Remingtons they just split open then fall off when I open the breech . Dirt in the "track" on the rotating bolt will stop you .

YMMV

     Thank goodness we didn't gundrill those bores any bigger than 9mm (.354").  Double D, if you somehow manage to cram one of those .58 cal. minies down your Krupp's bore, that WILL VOID YOUR WARRANTY!  Just so you know.

P.S.  Glad you fellows are figuring out the cleaning routine.  It is easy and doesn't take long at all.  CW, I like that guarantee; it's simple and easily understood.

Just to give some idea of scale, I include a picture of a 1:20.3 scale model of a 3 foot gauge 2-8-0 steam locomotive and the Krupp.  (I will add the picture after I determine the password for my website.)   >:(

    .590 Snider?     OOPS!       20mm, I hope not!  Save it for your future Armstrong gun.   Asron87,  We are glad No. 17 made it to you in good condition.  Smoke and flame pics are a must!

     GGaskill,  we are very happy that you posted that nice RR engine and coal car photo for scale.  We did some calculations and found out that the Krupp's scale is  1:25.3  So, I believe the train and the howitzer, if made to the train scale would result in a Krupp about 20% larger.  The Krupp tube would be pretty close to the length of the engine from the front of the boiler to the back of the cab body.

     Some assumptions were made to get a scale figure in 15 minutes instead of hours.  The man without the hat was assumed to be 72" tall so, we have a ratio solution of the number of inches the original tube is long.

                                 The man is one inch long on the print of the drawing image; the tube is 3.25" long. 
                                                                                           72:1 = x:3.25
                                                                                              234/1 = 234 
                                                                                                 x =  234"   The tube was 19.5 feet long.

      The Seacoast Artillery Co. Krupp is 9.25" long, so to get the scale of the seacoast gun, we calculate:     9.25 : 234 = 1 : 25.3      The Krupp's scale as we made it is 1 to 25.3, which yielded a howitzer approx. 20% smaller than the RR engine.     

FYI,

Mike and Tracy     


Posted once before, but here is a clearest drawing we have for clarity on our method for determining the howitzer's scale.

Interesting, I thought you somewhere said it was 1:20 so I used the 1:20.3 locomotive and tender.  I have some 1:22.5 scale also; maybe I will dig one out and compare it to the Krupp.

It's bigger than that.  In 2000 the average height of an adult  German  Male was 5" 10" -70" inches.

The mean average height of an enlisted man in the  U.S.Civil war was 67 inches, George Custer was 67.1 inches tall in 1876.

    Thanks George and Douglas, you guys are right, of course.  Do you see what happens every time we get in a hurry and do things Fast?  The result is that they become  'half-fast'!  The scale is 1:20 and we got that by taking our time and using an actual photo, the first image shown in this thread on page one.  This is the ratio method we used to determine the scale last July.

Using photo quality paper we made a 1:1 size copy of the original computer image of the old sepia photo.  Then we measured the 14" shell in the image with calipers and got .400".  The Breech dia. measured 1.087".  So, we ran the numbers again, as we did originally:         14:.400=X:1.087
                               14 X 1.087 = 15.218/.400 = 38.045" (Original Krupp Breech O.D.)
                                                                              1.900" (Seacoast's Krupp Breech O.D.)     38.045/1.900=20.02

The Scale we used to make this reduced size Krupp gun is 1:20  (Rounded from 1:20.02)  This was our method and the drawing on page 2 of this thread shows that ratio at the bottom.

So, George's train is very close to the Krupp Howitzer's scale and is excellent for size comparison.

Not to be too much of a rivet counter but examining the above drawing of the Krupp, it looks as though there are capsquares on the trunnions.  And some squarish thing too.  Any ideas?  Just artistic license?

Soot,

Thanks for the images, one thing I note are the pockets in front for the wheels,
capsquares, and it looks like some sort of angle/degree gauge on the turnnion,
from the looks of things the bolt patterns in the front and middle of the gun attach
the irons for the cap squares.

like he may be painting some lettering on it for the display....

That indeed is a most interesting drawing.

It appears that there are 3 rounds sitting there in front of the piece.
The middle one is new, the outer pair appear to have been fired?
Is that a base fuse/gizmo that has been unscrewed from the near one?

What is the 'tool' that the worker is holding (a staff with a forked thing on the end and more)?
