Hello Mylo,
Send me your email

[color=#000000]Hello Mylo,
Send me your email Mine is jdh16@uark.edu and I'll email some pics of the plans plus how I have made sections from the plans.
I dug the plans out, all scales/measurements are metric

Stoene,

I ordered those Schmidt

Stoene,

I ordered those Schmidt plans myself (after figuring out what a Euro is worth in Canadian dollars that is...). JWL mentioned the Kohl planrolle but I can't find them anywhere. I'm sure the Schmidt plans will work. Can't wait to see 'em. It would be great if you could mail me a few of the pics you mentioned.

Any ideas on how to size up the plans to 1]myles.h@sasktel.net.[/email] I live in Saskatchewan, Canada, about 100 mi north of the U.S. / North Dakota border. I don't think I could possibly live farther from the ocean....any ocean.

Myles.

The Type VIIC (and Type

The Type VIIC (and Type IXC) plans from Christian Schmidt are actually the Fritz Kohl plans. The publisher, Bernard & Graefe, has re-printed them in a slightly smaller size.

It's good to see these plans available once again!

Hi guys. I don't want

Hi guys. I don't want to appear 'Annoraky' but the VII B's were quite a bit different from the VII C's. eg Limber hole patterns, deck area around deck gun, saddle tank size (and hence shape). I seem to remember overall length was slightly different too. As the VII's were developed and space for new things was needed the designers simply added in a complete extra frame in the control room to accomadate. This also resulted in lengthening the coning tower. I have been reading a book on the development of the type VII. It is called "Type VII U-boats" by Robert C Stern. ISBN 1-85409-011-9

Just added this as VII B plan was requested. I assume because a particular U-boat is being built.

SteveUK,

Internally, you are correct.....the VIIB

SteveUK,

Internally, you are correct.....the VIIB and VIIC were a bit different.

From an external perspective the limber holes varied not only between VIIB/VIIC but also between the yard that built an individual sub....so it would be more important to worry about which specific boat and document it through photos of the prototype being modeled.

The VIIB was 66.5 meters LOA and the VIIC was 67.1 meters LOA. That's a different of 0.6 meters that was added in the middle of the boat to increase the amount of fuel that boat could carry. If you build a boat in 1/32nd scale that's a difference in the length of the model of 0.0188 meters (or 1.875 cm or 0.7382 inches) It's enough to worry about, but would allow someone to use VIIC plans if necessary.

The deck 'pattern' is, I believe, the same for the VIIB and the early VIIC boats, a gain allowing for yard-specific differences. The mid- to late-war VIIC had a different looking deck in that the construction was simplified by eliminating the individual wood pieces placed between the long wood strips (used to create the characteristic slotted deck look).

Now, don't forget the that the Atlantik bow was a design change done to the VIIC's and was instituted after the war started.

Hello Jeff. Funny I have

Hello Jeff. Funny I have just been reading some of your articles in my old SCR. They are still packed with relevent tips and how to's.

I have been trying to get to grips with the differences between type VIIB and VIIC ever since I decided to build my own starting with the plans. I was amazed how many plans there were that were quite different. Some were just plain wrong.
So I did my usual research - scouring as many photo's I could and decided that those in the Squadron "U-boats in action" looked nearest.

My comment about the "deck area around deck gun" is more about how much it overhangs the sides. In some photos (and plans) the deck area here seems to drop straight down the sides. In others the sides flare inwards sharply as they go down from this point as if the deck is wider. Then there are yet others that seem to have what looks like an extra piece of plating like a flange welded on to the deck. I imagine it was all developments of the deck area to give the gun crew more area to stand on when the gun was swung around broadside. I could be wrong

JWL,

Interesting.

I have received

JWL,

Interesting.

I have received my order of the Kohl plans as well. Subsequently, I will be building a VIIc (I never was "hung up" on building a b in the first place. A VII is what I was after).

After reading your comments on the individuality of the subs, I will be researching and modelling a particular sub in order that I produce it accurately. Which sub, not sure at this point. I'll dig around the net, find a U-boat Capt. that I like, and do his boat.

Thanks for the enlightenment.

Myles.
