42cm Marinekanone L/16, Gamma-Gerät 3D printed

Post by EPOCH3 » 07 Jun 2019 16:05

I have always liked the big 42cm guns used by the Germans in WWI and WWII.
Ugly for sure but a big piece of art in their own way.
There is very little technical data available for these weapons so I never
quite had enough information in order to do them accurately.

I basically finished up with my M1 and K3 designs and some new data became
available that answered a few technical questions I had wrt the design so I
decided to take a crack at Gamma-Gerät.

I attached a few pictures showing some initial work in progress and one
showing Gamma-Gerät relative size as compared to the Rheinmetal
M1 and K3 guns.

I decided to build Gamma in both 1/72nd scale and 1/35th scale and
even in 1/72nd scale its a pretty large little model :)

happy modeling

Hi - part of the benefits of modeling subjects from a technical perspective (as opposed to modeling for purely illustration or gaming purposes) is that it sometimes allows you to analyze the mechanical aspects of a design and figure out it's mysteries. A case in point. Gamma has this bracket arm assy looking thing with a cylindrical object connected to it towards the rear of the gun mount. I don't like adding a geometry to a model that I have no clue as to what it was for. I have tried to confirm and figure out what the object was used for and I think I now have a good guess. The large circular object is a counterweight and the bracket arm thing it is attached to flips 90 degrees when the barrel is being inserted to provide a roller so the barrel has something to rest on as is it slid into the mount/Wiege. The whole assy flips down and is secured into a stored position after the barrel has been inserted and as the rear deck platform is added. The counterweight just enhances balance that makes the effort of flipping it less difficult (since the assy has to be structurally heavy enough itself to support the heavy barrel).
