Acquired a Combat Models WWI US Naval 14" gun kit - massive vacuform.
Basic sides, gun, and decent plans. White metal railwheels and springs.
Great references for both the whole assembly and the various sub-assemblies - photos and drawings.
The Navy documented both the design and operations in great detail.

Evergreen and Plastruct will be needed in large quantities but the major frame and trucks are actually very simple. Just large.
I think there are about 1000 rivets as well - typical WWI construction
Any ideas how to do strips of rivets without doing each individually?
I hope to be able to post photos along the way - but it will be several months in the making.

Archer makes decal strip rivets in various scales, Micro Mark carries decal stip rivets in HO (1/87) and O scale (1/48). You didn't mention the scale of the kit. I've used the Archer decals before, an a scratchbuilt 1/16 scale B-17 fuselage section, and under a coat of paint, the decal film all but disappears.
Keep us posted on your build. Sounds interesting!
VR, Russ

It's 1/35th scale - the gun is longer than a 1/350 USS Texas
It is interesting to see how the US approached 12" and larger rail artillery design.
There is no "balancing" hydraulics at all. The 14"/50 caliber gun was the standard US battleship "rifle" and was weight balanced. The huge mass of the breech end of the gun balanced the barrel.
90% of the gun mount in the Naval Mk I gun was taken from their battleship mount including the mechanism to prevent the weight from binding the trunions.
Luckily there is a surviving one just across the river in DC at the Naval Yard and I'm going to get some detailed shots of the breech.
To get an idea of how large the gun is, go to
http://www.navweaps.com/Weapons/WNUS_14-50_mk11.php that shows a 14" being salvaged from the USS California and compare it to the workman
The Breech/Cradle assembly had a massive cube at the breech end that anchored the recoil/recuperators that was about a 4' cube.
I'll post some photos once I get the gun basically built.

Piles and piles of rivets!

Archer sells rivets as 3D resin decals you just cut them into strips and apply like decals except you place then BEFORE painting.

They offer them in various sizes and styles. Also in an alternating zig-zag patterned rivets for special applications as well as louvers and treadplate.

Would love to see photos of the unstated vac-form kit as well!

If space is an issue, one can still scratchbuild a N-scale one
