It won't start looking "fussy" until you start adding the plumbing.

That one is even worse than average, as it is a test article with extra maddness added.

The plumbing isn't too bad, once it gets diagrammed out. The one fussy area is the LOX pipes, individually to each injector cup and a central distribution octopus (sixteen pipes, actually) As far as scratch-build challenges go, the second hardest part is now done with the motor. The turbo-pumps will the the real beast, partly due to limited info, only photos and no drawings, so I'll have to best guess it all, and that it is really fiddly. Third hardest will be the fins, mainly in the areas of the fillets and around the exhaust control vanes.

I actually have a few parts from a V2's combustion chamber (and a whole pile of V1 parts).

Oh really!? What kind of V-1 parts?

For the V1 I have the tail rudder, a secondary detonator impact fuze, several parts of the auto pilot, pressure regulator, a rib from the tail, and a few odds and ends. I'd like to make some sort of display out of it all eventually.

Neato! I've got access to several V-1s up here for reference. The Museum of Flight has a Nordhausen reconstruction Fi103A1 with the trailing radio antenna option. Paul Allen's collection has a '103A1 and '103Re4, both likely Nordhausen reconstructions with extras for the Re4. They are all with original fuselages and likely motor tubes, but the wings are clearly modern replicas, but look great.
And at the Olympia Air Museum, there are a further pair of V-1s, but rather crude reconstructions using original rear fuselage and nose caps and wood and fabric mid-fuselages, motors and wings. The original parts might be Nordhausen salvage, as the rusted parts and possibly original paint do look like the real thing.

When I saw the thumbnail for this I thought for a second it was a piece of slipcast pottery next to it's plaster mold.

Felt kind of silly after that.

Although, that would make a pretty neat flower pot as a conversation piece.

Neat.

I was lucky to buy one of those re-issued V2 rocket & launcher kits that Revell made ages ago. It has a million parts, though, and ought to have a little painting, so I've never gotten around to making it. For retirement at age 90, I suppose, and when I have a large 12 room house to display everything.

You've really got some work ahead of you, but at least it's good to see that you've got a better understanding of the subject than the original Vacuform model makers. Nice lathework too.

My first impression of the image was 'Chocolate rocket engine! Yum!'

I await seeing a V2 with it's guts.

Awesome! I bought a flying v2 kit at our last desert heat rocketfest. And somewhere, i have a reloadable G motor casing. I have always loved that vehicle. I look forword toseeing fotos of the completed model. Please do post!
