Revell 1/96 Saturn V: S-IC Stage – Part 2

Last time, I described how I needed to extensively modify the front and back ends of the Revell S-IC stage, using resin parts from RealSpace and New Ware, combined with some custom decals and a little scratch building.

Next, I needed to assemble the component parts of the stage—the fore and aft skirts, the intertank ring, and two styrene sheets that needed to wrapped into cylinders to represent the fuel and oxygen tanks.

As usual, I turned the styrene sheets inside out, so I could prime and paint the stage in a uniform pattern of black and white. (New Ware provides decals for the USA markings and the American flags.) Also visible in the picture above are the parts for the two long service tunnels that carried wiring up the outside of the tanks. The kit parts are undetailed and oversized, and New Ware’s solution to this is to provide a set of photoetch parts, ribbed to reflect the real surface of the service tunnels. These are supposed to be wrapped around the kit parts, and excess plastic pared away. The kit parts don’t really produce the right shape, unfortunately—the original tunnels were pretty close to being hemicylindrical. So I wrapped New Ware’s photoetch around lengths of 7mm half-round rod from Maquett instead, which produced a fairly nice result.

At this point, I noticed that New Ware’s tunnels were a little shorter than the kit parts. I checked against David Weeks’s Saturn V scale drawings and found that New Ware was pretty close to the correct length, and thought no more about it. (In retrospect, I should have thought more about it.)

So I wrapped the styrene, assembled the stage … and discovered that the service tunnels didn’t span as far as they should. I could have one end of the tunnel correctly located, but the other end wouldn’t reach far enough on to the skirt at the opposite end of the stage. More measuring ensued, and it turned out that Revell’s S-IC stage is almost an inch too long for the correct scale, with most of the excess length in the forward tank and the intertank. Well, sigh—they finally caught me out. I couldn’t see a good way to disassemble the pieces and trim them, so I accepted the inevitable and positioned the tunnels so that they leave a larger chunk of forward skirt exposed than they should do.

The engine fairings I kept separate, and painted in their final pattern of white, black and metallic. They were going to have to go on after I’d added the engine and firewall assembly I completed last time—the structural braces inside the engine fairings meant that each fairing assembly would need to be slid on sideways once its corresponding fairing firewall was in place.

So I primed and painted the cylindrical stage, leaving the final demarcation line between black and white on the aft tank to be completed once the fairings were in place. Then the firewall and engines were put in place, double-checking the correct orientation of the central engine. Then the fairings, then the finalization of the black stripes on the aft structure.

By this time, the whole thing was beginning to take up a lot of room on the workbench. Here it is, waiting for a coat of gloss and the New Ware decal set:

Positioning the American flags on the overlong forward tank needed a bit of calculation to make sure they were positioned in the correct proportion between the top and bottom margins, rather than working from the original measurements.

Finally, before the last coat of varnish, I added the delicate telemetry antennae to the forward skirt. (I knew that, if I added them any earlier, I would knock them off while preoccupied with decal positioning.)

And that was that. The literal final stage of this project:

Except … there’s one more small component to build before the project is complete. That’s what I’ll post about next time.

  1. This has been an absolute master class in model making. Thank you for so much detail and information. When is the small LEM component coming up? Thanks again, Al.

  2. Thanks for the kind comment.
    The LM will be up next week. A few weeks after that there will be a final summary post featuring some photos of the assembled model, and a sort of stage-by-stage photographic index, describing the necessary modifications and providing links to the relevant parts of the blog.

  3. I have nearly completed my 1:144 Airfix Saturn V, now at the decal stage. I then have the Educraft Launch Umblical Tower to construct and then the Crawler Transporter. As a seven year old watching Apollo 11 landing on Tranquility Base has stayed with me and has been an inspiration. The build you have done is awsome, looking forward to the LM (LEM). All the best Al.

  4. The Educraft stuff is a little daunting! I’ve never built a paper model before, but I have their 1/32 Lunar Module in the stash. I have a few other space-related projects before I get to it, though.
