I have been working on the design and building methods for the USS Holland for about 2 years now and finally starting to machine parts.
The hull will be metal spun out of 260 casing brass and all of the fittings will be lost-wax cast in 342 brass.
I have all of the cad drawings required to produce all of the parts to factory specifications.
I am building 6 kits and 3 are already spoken for.
This is not a profiting project but a labor of love.
I am also designing a Jules Verne style amphibious steam-propelled screw-drive vehicle.
I am posting some images and any constructive advice is very welcome.
