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?

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.

More detail work...and the port spare Whitehead torpedo...

Creating these CAD models I can easily spend 1-2 days modeling a manual piston water pump from 1900....

And when the pump is done, it find ts place almost invisible under the port ladder to the Otto motor....

Working on the plumbing.....I'm currently designing the water piping. The arrangement is based on the John Lambert plans, which are quite detailed about the section in blue, but as I'm missing a true piping plan, most hoses will end in the nowhere. Does anyone have more information about the water and air piping in the HMS Holland 1?
