HMS Holland 1 - 3D CAD model in the making

[DrSchmidt]

I'm working on the general arrangement of the various tanks. The boat had 6 torpedo compensating tanks, 2 for each of the three torpedoes it could carry. One in the tube, a spare on port and starboard.

Starts to look like a boat:

The torpedo tube and the compensating tank are close to be finalized....some bolts and rivets are mssing.

[DrSchmidt]

The Holland is a long ongoing side project. The torpedo tube and its intricate interlock mechanisms is a project of it's own. My understanding is, that one opened the torpedo hatch by cranking it open via thread rod and at the same time compressing ait in a cylinder. Opening the hatch also actuated a lever mechanism, that interlocked the breech door from opening. Then you could open the firing lever guard, which also actuated a safety valve, preventing the accidental firing of the tube. Flooding of the tube was done via two valves, the levers of which also interlocked the breech door from opening. Complicated stuff and I still miss information....anyone with some documents about whitehead torpedo tubes?

I use ViaCad Pro ... but there are other good alternatives around. My resin printers are by Elegoo, I have the Mars and the Saturn. They get better every year and are not very expnsive.

Thank you, Andreas. I do appreciate the information.

A bit more work on the Holland. Currently I'm detailing the torpedo compensating tank and the firing valve of the torpedo tube. At the time of the Holland riveting was the deal....and they used many of them.

Andreas,

I may be too old to start to learn a new field of endeavor, but would you share the 3D CAD software you are using? And also, your go to Resin printer you like to use.

Thank you,

Rob

[DrSchmidt]

Yes I do....all my boats are based on self-drawn CAD files.

[Das Boot]

Hey Doc, do you design your own 3-D CAD files? I’m too lazy to go back and try to find the answer. Anyway, looking forward to the beginning of this build.

[DrSchmidt]

More tanks and bottles...and the batteries. The batteries were packed in wooden boxes, so in the picture one only sees these wooden boards, In case of a build, I'll have to cut a bit of the superstructure to make the at least some batteries visible....

[DrSchmidt]

Further progress on the internal structures. water tank, compensation tanks, compressed air bottles, torpedo firing tank, lockers and boxes. This will be detailed later...

[DrSchmidt]

I'm further refining the internal structures of the Holland 1. I added the main ballast tank and redesigned some bulkheads. Difficult, as I don't have a tank plan for the Holland, an the Lambert plans don't have enough detail for a perfect reconstruction.....

[DrSchmidt]

And in position in the bow section of the Holland....

Working in the kingston valves for the main ballast tank. This is the port one....
