I recently bought the Dragon 1/72 Mercury Redstone kit (review at Modeling Madness (http://modelingmadness.com/scott/misc/realspace/dragon/mr3.htm)) primarily for the Mercury capsule. The capsule is nicely detailed; no interior but far worse, no heatshield. The retrorockets and the open door on the nose are on the sprue, so I don't know why they left the heatshield off.
Since I couldn't build the capsule on its own (I didn't feel like scratchbuilding the heatshield) I thought that turning it into a one-man space station would be a novel idea. I had a vague recollection of a planned long duration Mercury, so I googled it and found Project Gemini: A Chronology (http://history.nasa.gov/SP-4002/contents.htm). In their list of illustrations (http://history.nasa.gov/SP-4002/contents.htm), there's figure 3, a proposal for a one manned space station based on Mercury:

One of the tubes that makes up the Redstone kit was just about the right length for the orbital laboratory. An engine intake from an old Revell Battelstar Galactica viper kit fit perfectly as an adapter shroud at the rear. Since I don't plan on building the Atlas Agena stage, I'm going to put a small engine in the rear. I didn't like the bare look of the station, so I made a couple of 1960s style solar panels:

Everything is tacked on right now. The inflated docking tunnel is made of Depron coated with some superglue and Acryl marine glazing putty. The fairing is just styrene. I still need to add some external doodads and reshape the tunnel.
-
Oh, that looks quite promising. I wonder if this was a predecessor to the MOL?
-
Now that's interesting! I had to look twice at the access tunnel before I figured it out ( but its early
Monday morning...) the 'shield' over the tunnel is probably the oddest thing to my eye-I assume that
would have been flush with the capsule surface on launch.
Don't forget some camera windows-I suspect this bird would have been pretty much dedicated to
reconnaissance.

Wow! That's such an awesome concept vehicle, one I never heard of! Super cool man.

Frank, way cool project. Lookin' very nice. :)

Wow Frank, your projects just keep getting better and better!
This is an awesome concept and already it looks like you're well on the way to building a real stunner if those fantastic solar arrays are any indication!

Thanks for the comments! I'm glad I was able to turn my disappointment with this kit into something fun to build.
Evan, this does look like an early MOL concept. The Mercury capsule had a lot of design issues (Gordon Cooper had to make a manual re-entry on the last Mercury flight) so it's not surprising that they moved on to Gemini ASAP.
Craig - it took me a while to figure out the tunnel arrangement. The fairing was easy to make, the inflatable tube is what's taking up most of the time.
The astronaut would probably have to climb into the capsule through the fairing and somehow through the deflated tunnel. I suspect that the fairing hatch was wide/long enough (or hinged at the front) to allow the tunnel to hang outside the fairing while the astronaut was shoe-horned into the capsule.
I don't know if the fairing would have detached in orbit once the tunnel was inflated, but since I made it, I think I'll assume that it stayed attached (as a shield). The astronaut would have to undo the Mercury hatch (probably hinged, to keep it from floating around and the edges from puncturing the tunnel) then squeeze his way into the tunnel, close the hatch, then open the station hatch. I doubt he would want to go back and forth much; he'd probably spend the two weeks in the station part. At 182 cu. feet (vs 60 cu feet), that was almost as much room as an Apollo command module!

The spirit of whiffing in a nutshell! Great save and a fascinating subject :)

I've made some progress over the last two weeks. I replaced the "organic" tunnel with a plastic tunnel from the Pegasus "Power Plant Construction set":
(http://frank.bol.ucla.edu/Images/merc/merc3.jpg)
The aluminum is just bare metal foil and it's supposed to represent a thermal blanket. I may or may not keep it.
In addition to the single porthole in the picture above, I added a telescope/camera port (closed):

The dull aluminum and the shiny aluminum are the same paint. I bought some Createx Auto Air Colors acrylic paints a while ago. This is the first time I've used this paint and it's fantastic. The shiny aluminum is straight from the bottle (thinned with windshield wiper fluid for airbrushing). The dull aluminum is the same paint, mixed with Vallejo matt varnish and thinned for airbrushing. Easy to mix, easy to clean up and the results are as good as other lacquer or enamel based metallics.
Since it's an acrylic (and compatible with Vallejo, as I found out) you can mix up quite a range of shades.
Here's a picture of the bottle info:

Next I have to add a couple of antennas (maybe a radar dish) and some details. I may redo the solar panels, though.
-
Looking great so far. Love those Pegasus accessory kits. Still trying to come up with a good reason for stocking them in the parts box.
-
Looking good! The new tunnel is great :)
-
This reminds me of the "Hammer Lab" in the Novel "Lucifer's Hammer" by Niven and Pournelle. Your latest progress looks great! :)
-
Wow that's "out of this world" awesome, Frank!
I really like the new tunnel and I think the foil replicates a thermal blanket wonderfully!
The colors appear very realistic as does the cool camera port.
I'm really enjoying following this project!

Thanks guys. I hate painting and my favorite part of this already fairly painless build has been the aluminum paint. It's easy to use and doesn't stink (even with a paint booth, I could still smell metalizer fumes).
Jeff - I have the Power Plant and Chemical Plant construction sets. The shapes are great, but this is the first time I've needed to use a part.

I saw the kits on SSM a month or so back and started to load up the shopping cart with a few items, before I knew it the total was in the three figures category and never having purchased from SSM before I got cold feet and quit my shopping session.
-
One of a kind subject and your build is right on. :)
Fits into a space pioneers display and likely to fool many who are not in the know.

Jeffry, Can't help with the three figures catagory but I can vouch for the SSM store...great service and speedy delivery, if you find yourself there again you can buy with confidence. :)

I think this one's finished:
(http://frank.bol.ucla.edu/Images/merc/merc11.jpg)
I had the capsule and tunnel perpendicular to the solar panels, but that looked too symmetric. I rotated the tunnel (or the panels) slightly and I think it looks better. The engine is a plastic pearl and the nozzle is from the kit.
(http://frank.bol.ucla.edu/Images/merc/merc10.jpg)
I brush painted the fairing; I'll remove it and paint it by airbrush. It's held on with some museum wax.

Not much in the way of sensors, but I see that my cat assistant added one of her cat hairs:

I added the stabilizer panel to the nose:
(http://frank.bol.ucla.edu/Images/merc/merc6.jpg)
This is the one thing that is so annoying about this kit - it has all the parts to make an in-orbit Mercury except for the heatshield. Other than that, this was a fun and very enjoyable build.
Here's a quick & dirty Photoshop:

Excellent build. The photoshop is cool.
Send a copy to John Glenn. ;D
-
That is awesome Frank :o :-* BTW I am in Cypress ;)
-
:)
-
Wow is that fantastic! Looks museum quality and the photoshop "money shot" is icing on the cake!
Most excellent, Frank!

Finished up beautifully! :-*

Looks great, Frank.

Very cool! :)

Just awesome..Very very nice indeed.. Love to gather some more details about the project.

Well done!
That looks just like the old Mirro cookie press my mom had in her kitchen growing up.

Very realistic aluminum finish! ;)

Beautifully done :)

Good to see the feline assistant getting full credit. I note that the Chinese make fine brushes out of cat whiskers. Maybe the shedding would lessen if you threatened to make your own fine-detail brushes?

Nah, Espresso is a good (but fuzzy) cat assistant. Her main job (besides keeping me company) is to keep her noisy hurricane of a sister from bugging me while I'm building or painting. She's also surprisingly good at finding and pointing out small dropped parts.

My cats have always been of help in finding "lost" things under my worckbench. My present cat,Freya, will lay at my feet while I'm working at my worckbench. You know in their minds, they know their own job is to keep their humans under control and out of trouble.
