HMS Holland 1 - 3D CAD model in the making

[DrSchmidt]

Thanks Dave....I hope to make it a model.

[He Who Shall Not Be Named]

Thanks Dave....I hope to make it a model.

oh!... can I play? Let's r/c that sucker. How about it?

[DrSchmidt]

Designated scale would be 1/35 .... about 55 cm in length. Would be a nice RC size. But before that ... SM U1. After the Type II with interior I'll get the U1 going.

And the worm gear drive of the stern control plane....

[DrSchmidt]

Something I really don't like....designing the linkages. But it turned out good.

[DrSchmidt]

And the control linkages in the ful CAD-model:

More bits and pieces....I added the drive for the exhaust box (the one with the red wheel). All the exhaust lines of the four cylinder Otto motor ran into a single box, from which the exhaust gases were expelled. The box had a water-tight lid, that could be opened and closed, an early variant of a modern exhaust main valve. The actuation of the lid was driven by a push rod that was moved by a thread rod driven by a bevel gear that was actuated by the red hand wheel.

Were there any kind of covers around the gears or were they open to the inner space? I presume one could easily get ones fi gers or clothing cought...

A greatly detailed model, Dr.!

[DrSchmidt]

From the drawings and photos I know, they were not covered. Sub sailor meat grinder......

More detail work, This time the torpedo loading hatch. A rather large rectangular cut through the hull and 3 frames. I think that makes for an excellent structural weak pint in the hull, The hatch was closed by a rectangular plug, that was held down with a set of bolts and nuts.

Details on the torpedo loading hatch. The hatch was closed with a rectangular plug that was held in place using threaded fasteners.
