1/72 Gemini Spacecraft
Discussion
1965 sees the 50th anniversary of the start of the US Gemini manned space programme. Gemini was instigated when it was realised that the jump from the very simple Mercury spacecraft to the much more sophisticated and capable Apollo was far too big a leap.
It was decided that an interim project was required which would allow NASA to learn how to carry out some basic techniques that would be required for Apollo - orbital manoeuvers, orbital plane changes, rendezvous and docking and Extra Vehicular Activity (EVA or spacewalking).
Because the project was put in place very quickly, permission was received from the government to skip the normal competitive tendering process and the design and construction of the spacecraft was allocated to McDonnell - who had also built the Mercury space capsule. The Apollo spacecraft had already been awarded to North American Aviation Inc.
The kit I have chosen is the fairly new (2012) 1/72 model released by Dragon. Being modern, it is very neatly moulded using the latest CAD and slide mould techniques. It looks like it will go together really well.
Despite its newness, it's not [perfect. In particular, I am disappointed in the fact that the forward facing windows of the space capsule are not cut out of the sold plastic. I assume they expect the modeller to just paint a representation of the window on each hatch. I don't think that this is satisfactory and I will chain drill and cut our (carefully) proper window apertures and either use Crystal Clear or Acetate to represent a proper window.
The kit is arranged to represent Ed White's spacewalk on Gemini 4 in 1965. You get two astronaut figures which, for some odd reason, are moulded in bendy polythene rather than hard polystyrene.

Dragon supply three hatches. Two are for setting in the closed position. An extra one features hinges to allow for the hatch to be posed open for the spacewalking astronaut. I've cut one out window aperture. A little bit of tidying is required.
You can see how they have been moulded solid by Dragon.

Nice project Eric but I reckon you are going to need acetate for those windows
I can't see Krystal Kleer filling that size of gap convincingly but thin acetate could be carefully carved to suit, probably in the same time you spent trying to encourage KK to cross the bounds of sizefullness
I like the kit a lot though
Obviously they made the crew flexible for re entry and spacewalking duties
Even in polythene they look pretty good

After a brief hiatus due to performing on stage all of last week, it's back to the Gemini spacecraft.
I've primed and painted the internal parts and started on the two crew.
I discovered to some consternation that only one of the crew has been supplied with a set of arms. I don't know what went wrong there.
So, to rectify the situation I decided, rather than try and scratchbuild some arms for the "armless one", I'd swap his head onto a fully armed alternative. It so happens that it is the seated astronaut inside the capsule who has been left devoid of appendages. Therefore, I decided that it didn't really matter if his body was not fully fitted out as an astronaut. The hatch will be closed over on him so he will mostly be invisible in the cockpit.
He may need a bit of fettling in order to ensure the lid closes down over his head. The Gemini capsule was extremely cramped inside.
The other "floating" astronaut is fully equipped in the limb department and one of his hands is holding the small gas manoeuvering device which was tested on Gemini 4 by Ed White. They both need priming and painting so that is today's first job.

Of course, I'm well aware that this is also a deliberate attempt on your part to portray Ed in his massively over-inflated and stiff suit, struggling to regain the safety of the spacecraft 
!!!
Only Ed didn't have any such problems. In fact, he was enjoying himself so much that they had trouble convincing him to get back in -!!!https://www.youtube.com/watch?v=cSrAF5DgknM
You might be confusing White's EVA with the one performed a few weeks earlier by Alexei Leonov who had real problems with a ballooning suit.
Yes and no. I know that you know your stuff; this is for those unfamiliar with the drama of the early space walks. Leonov very nearly died, his inflated suit resulted in his hands no longer sitting in his gloves and the telescopic airlock compounded his woes.
White described his return to the craft as the saddest moment of his life. But the early exhaustion of his manoeuvring propellant, his subsequent efforts to haul himself around, avoiding the hypergolics expelled as McDivitt kept the craft oriented, and his dallying in returning to the capsule, coupled to the stiffness of his inflated suit, almost resulted in disaster, something that NASA kept quiet about for decades, not wishing to lose face in the space race. He had difficulty contorting himself back into the confines of the tiny craft, McDivitt was only able to offer limited assistance and closing the hatch proved very difficult indeed, as it had done so to open (a mechanical failure, I seem to remember). White's pulse rose to a very high rate (178 bpm, I've just looked it up) with McDivett having to haul down on White as White struggled with the locking lever.

There certainly were difficulties on White's EVA - but I don't think it got anywhere near as life threatening as Leonov's EVA did. In some ways, because White's EVA was not that traumatic, it gave NASA a false indication of the true difficulty of EVAs and the next EVA carried out by a NASA astronaut - Gene Cernan on Gemini 9 - very nearly did kill the astronaut. In fact, NASA didn't really get a grip on EVA until the last Gemini flight - Gemini 12.
Finished. A neat little kit with virtually no filler required. It's not 100% accurate but it is good enough for me.
The only significant changes I made were the cutting out of the window apertures and I also fabricated a representation of the Infra Red Horizon Sensor. Gemini uses this device to "know" what way up it was pointing - crucial before firing its orbital manoeuvering rocket motors. The kit depicts this device as it is during launch i.e. under a streamlined fairing. The fairing was jettisoned immediately after orbit was achieved to allow the device to see the horizon so you would not see the fairing in any pictures of a Gemini in orbit..
My tribute to Ed White and what he accomplished a half century ago.
Also, another excuse to buy some Rolos
