HMS Holland 1 - 3D CAD model in the making

[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?

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

Starts to look like a boat:

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.

Fitted the remaining air tanks and started modeling the holding brackets. Also added the spanner rack on the port forward compensating tank.....slow work.
