Simon - Those are brilliant. I've been looking for some clear, precise drawings of the Turm IV. Thank you for posting.


When did the economized version of the Turm IV first start being used? In modelling U-371, it had its Turm IV installed in early Sept. 43. She was sunk on 2 May 44. Between those dates (or possibly during the Turm refit) she had Armor Boxes installed on both sides of the Bridge. They had not been removed prior to her sinking.


I'm just wondering how close your drawing is compared to my boat. I only have one photo, a screen grab of the boat as it passed, showing part of the Turm and the Stbd. Armor Box. It is clearly   U-371 as KptLt. Mehl's insignia is plainly visible on the Armor Box.

I would say sometime around Mid-43 however, Dougie may have a better idea.

Hi there Folks,
the last years I build the Engel VIIc. Because of very much measure fails at the Floodholes and rivetlines we decited to rebuild the complete Floodholes and Rivets. Now my Questions, what are the correct measure of the Floodholes? My Measure from Pictures (big hole lines at Bow and Stern) are 390x150mm, is that possible? And wich is the correct high between both hole lines?  The second measurement that is not correct is the height of the long line lower the conning tower (I think 100mm?).

Attached my actual drawing from the bowlines.

Thanks alot, and a big thanks and thumbs up to snowman, max. respect for your work and stying power!

best regards
Sascha

Looking at war-time photo's of U-977 and U-1305, I calculated:
Rivet ↔ 50 mm ↔ 400 mm ↔ 50 mm ↔ Rivet : height = 130 mm

For the last four weeks I been working on the aft section of the casting around the aft torpedo door (green and yellow casting). Some of the most complex modelling I done.

This is astonishing!
I have been popping in here from time to time over the years and watching this endeavor proceed from layered 2D drawings to these fantastic 3D models.  This is truly amazing work.  This may be the most complete 3D rendering of a uboat ever made.  It will be a research tool for historians for hundreds of years to come.

Bold Hull Cover Plate

If anyone is thinking about the adding a the Bold opening to there model below are the measurements base on U-995.

After checking the measurements with my 3-D model I noted 5000 mm from the bottom of the keel was to high. After checking a better photo, it should be 4450 mm above the keel.
