STS 41c - Challenger and LDEF


Recommended Posts

This'll be the Tamiya 1/100 Space Shuttle kit depicting the deployment of the LDEF,  the Long Duration Exposure Facility.

 

 

Gluing the fuselage halves ...

 

2v2JUSQzyxAnAAS.jpg

 

 

The Payload Bay will be open and the kit's PB is quite inaccurate ... so I shall rework it ... a little.

 

2v2JUSbvjxAnAAS.jpg

 

 

And rather than semi-circular, it's cross section is more elliptical, but I'll work with this ..

 

2v2JUSKMWxAnAAS.jpg

 

 

The aft end needs to be squared off on the bottom, so I cut out a section ...

 

2v2JUSbpyxAnAAS.jpg

 

 

Reinforcing the seam of the fuselage

 

2v2JUSbAGxAnAAS.jpg

 

 

 

The OMS pods had a lotta parts and the fit was ... poor.

 

2v2JUSbECxAnAAS.jpg

 

 

The various subassemblies

 

2v2JUSbeWxAnAAS.jpg

 

 

Starting the build of the LDEF. The forward and aft bulkheads ...

 

2v2JUSbYdxAnAAS.jpg

 

 

One of the references ...

 

2v2JUSbkGxAnAAS.jpg

 

2v2JUSbyGxAnAAS.jpg

 

2v2JUSbq5xAnAAS.jpg

 

 

The kit had a piece of cargo which I may use to depict the capture hardware in the aft end of the Payload Bay.

The EVA windows in the fwd bulkhead were too far apart, so I repositioned 'em ...

 

2v2JUS195xAnAAS.jpg

 

2v2JUS1njxAnAAS.jpg

 

 

Added styrene bits to patch various notches ...

 

2v2JUS1AdxAnAAS.jpg

 

 

Made the Payload Retention Mechanisms and added some styrene pegs to the bulkheads for the handholds ...

 

2v2JUS1KNxAnAAS.jpg

 

 

Added some details to the kit's SSMEs with copper wire ...

 

2v2JUS1HnxAnAAS.jpg

 

 

Formed a new interior of the Payload Bay ...

 

2v2JUS17GxAnAAS.jpg

 

 

And the result ... 

 

2v2JUS14NxAnAAS.jpg

 

 

As this is going to show an on-orbit situation, and the elevons were free-floating, I cut them off the kit's wings to reposition them ...

 

2v2JUS1cnxAnAAS.jpg

 

2v2JUS15yxAnAAS.jpg

 

Next up will be a piece of payload.

This mission also captured and repaired the Solar Max satellite and the fixture that retained the satellite during repairs needed to be built too.

The fixture in the aft area of the Payload Bay needs to be built ... using a kit part of Spacelab and a sketch in Illustrator glued onto a sheet of styrene ...

 

Here's a ref photo ...

Dry fitting of the Payload Bay

 

2v2JUScKqxAnAAS.jpg

 

 

The EVA windows are getting patched because I won't use the kit's glass ... just a decal.

 

2v2JUScdNxAnAAS.jpg

 

2v2JUScg8xAnAAS.jpg

 

 

The gap between fuselage and wings were filled sith strips of styrene ... filed and sanded.

 

2v2JUSfu5xAnAAS.jpg

Thanx Keith ... but not necessary. I've got pul-enty of images and have to create my own decal of each material on the LDEF too, so the images I've accumulated will suffice.

 

The cockpit won't be visible but I applied the kit's Instrument Panel decals anyway. Just for the fun of it!

 

 

2v2JUSfAzxAnAAS.jpg

 

 

To try to replicate the Insulation batting on the Payload Bay surfaces, I like to use Grocery Bag plastic ... cut in small squares and applied with One Coat Rubber Cement.

 

2v2JUSfbyxAnAAS.jpg

 

 

The Fwd bulkhead after the texturing ...

 

2v2JUStcrxAnAAS.jpg

 

 

The Aft bulkhead after applying the grocery bag plastic ...

 

2v2JUSAL5xAnAAS.jpg

 

 

The End Effector from the kit has a claw ... this needs to be reworked.

 

2v2JUSfRjxAnAAS.jpg

 

 

The new End Effector is at lower left and the RMS ( Remote Manipulator System ) has been modified and accurized. I also built the Ku Band antenna and have two tiny cameras made for the PB bulkheads.

 

2v2JUSAcqxAnAAS.jpg

 

 

Clamping the multi piece OMS pods ... 

 

2v2JUScD8xAnAAS.jpg

 

 

The poor fit kind of surprised me ... but with some filing and sanding, it'll look just fine!

 

2v2JUSfLoxAnAAS.jpg

 

 

Filling the gaps with scraps of styrene ...

 

2v2JUSf5oxAnAAS.jpg

 

 

... and putty ...

 

2v2JUSfz8xAnAAS.jpg

 

 

Adding some attaching plates to the cockpit window ... yes, the kit windows are blue ... 

 

2v2JUSfTrxAnAAS.jpg

 

 

Attaching the bulkhead ...

 

2v2JUSA55xAnAAS.jpg

 

 

Filling the gaps in the belly ... with a little bit of elbow grease, this'll get done too!

 

2v2JUStENxAnAAS.jpg

Puttying the belly for the first time ...

 

2v2JUS7bWxAnAAS.jpg

 

 

After the 2nd sanding ...

 

2v2JUS7RVxAnAAS.jpg

 

 

the fit of this kit is par for the course ... poor, but entirely fixable.

 

2v2JUS7BgxAnAAS.jpg

 

 

Adding little supports or fairings to the base of the Tail

 

2v2JUSYVSxAnAAS.jpg

 

 

Filling and sanding the Chines ...

 

2v2JUS7VPxAnAAS.jpg

 

 

Sanding the window seams ... I put on a sacrificial decal to protect the clear plastic ...

 

2v2JUSsSDxAnAAS.jpg

 

 

Bulkheads are done ...

 

2v2JUSsMDxAnAAS.jpg

 

2v2JUSPLhxAnAAS.jpg

 

 

Free Floating elevons ...

 

2v2JUSkoqxAnAAS.jpg

 

 

Adding some detail to the Aft fixture ...

 

2v2JUSsnixAnAAS.jpg

 

Next up will be the Payload Bay doors and the LDEF itself ...

The radiator panels on the Payload Bay doors were made from grooved Evergreen sheet. 

 

2v2JUSP6CxAnAAS.jpg

 

2v2JUSPmgxAnAAS.jpg

 

 

Using some tubing and some clamps, the panels were glued to the kit's doors.

 

2v2JUSPdqxAnAAS.jpg

 

2v2JUSizyxAnAAS.jpg

 

 

The kit's Radiator panels were nice but completely inaccurate.

 

2v2JUSknTxAnAAS.jpg

 

 

Using 0.020" styrene rod, I made the handholds. They are on a sheet of waxed paper for gluing.

 

2v2JUSkYmxAnAAS.jpg

 

 

Installing the handholds

 

2v2JUSkTTxAnAAS.jpg

 

2v2JUSkcSxAnAAS.jpg

 

 

... and DONE.

 

2v2JUSijqxAnAAS.jpg

The LDEF took a lot of sanding sessions ...

 

2v2JUST9WxAnAAS.jpg

 

2v2JUSTcFxAnAAS.jpg

 

 

Ready for a little primer ...

 

2v2JUSTadxAnAAS.jpg

 

2v2JUSTVhxAnAAS.jpg

 

 

... and some more sanding ...

 

2v2JUSTzhxAnAAS.jpg

 

2v2JUSSUGxAnAAS.jpg

 

2v2JUSSaLxAnAAS.jpg

 

 

This is the Map for the various Materials to be attached to the LDEF ...

 

2v2JUSTk5xAnAAS.jpg

 

... and my homemade decals ... after a lot of researching ...

 

2v2JUSTNWxAnAAS.jpg

 

 

... attaching the decals ...

 

2v2ENuw95xAnAAS.jpg

 

 

The decal paper/film, in the background, is garbage.

The decals' adhesive was poor, the film was very thick and didn't conform to surface detail ... this awful paper made this more like work than fun ...

 

2v2ENuwugxAnAAS.jpg

 

2v2ErE7CNxAnAAS.jpg

 

2v2ErE7LrxAnAAS.jpg

 

That'll do for now!

 

till next posting!

Hello Pete,

wow.gif look here, that seemed familiar to me from the ARC Forums, although your stage name initially has irritated me a bit. smiley215.gif

But then I thought that couldn't be a coincidence and have compared it. top.gif

 

Let's get ready to rumble ... up040577.gif

The Repair Fixture was glued in ...

 

2v2JUSDYhxAnAAS.jpg

 

 

And Masking for Paint ... To get the pattern for the Hatch, I cut through the paper to the tape under it ...

 

2v2JUSDwgxAnAAS.jpg

 

2v2JUSDbSxAnAAS.jpg

 

2v2JUSDuVxAnAAS.jpg

 

 

During a sanding, the window got pushed in and a couple of styrene strips were glued in to add a little more bite.

 

2v2JUSDiTxAnAAS.jpg

 

 

The belly was sprayed Grey in prep for the lovely decals ...

 

2v2JUS4vqxAnAAS.jpg

 

 

2v2JUSDhWxAnAAS.jpg

 

2v2JUSDrVxAnAAS.jpg

 

 

After repainting the window, the nose cap got some paint too ...

 

2v2JUS4sGxAnAAS.jpg

 

 

The nose gear door decals didn't quite fit, but with a little paint the gap was touched up ...

 

2v2JUS46dxAnAAS.jpg

To replicate the blankets, I use First Aid Tape, 2 different textures. Cut them out individually and stick 'em down ...

 

2v2ErE7nzxAnAAS.jpg

 

 

Using a photocopied guide ...

 

2v2ErE7qoxAnAAS.jpg

 

2v2ErE7GMxAnAAS.jpg

 

 

Attached the SSMEs ...

 

2v2JUSTnSxAnAAS.jpg

 

 

This decal material is awful ... The homemade decal printed out alright but ...

 

2v2ENuwHnxAnAAS.jpg

 

 

... it didn't adhere to the plastic. My thumb is under the applied decal. I discovered the poor adhesion by blowing on it, and it lifted. It was all sealed with Future, but still ...

 

2v2ENuwaqxAnAAS.jpg

 

 

Adding the tiles to the OMS pods ...

 

2v2Erc7FmxAnAAS.jpg

 

2v2Erc7qWxAnAAS.jpg

 

 

Adding tiles to front section ...

 

2v2Ej2GV8xAnAAS.jpg

 

2v2Ej2GTrxAnAAS.jpg

 

2v2Ej2GCzxAnAAS.jpg

 

 

... and added some details to the Payload Bay ...

 

2v2Ej2GLdxAnAAS.jpg

 

Getting closer to the finish line ...

With all the necessary sanding, the windows had thinned down to a point where I punched through it ... 

 

2v2Ej2GGNxAnAAS.jpg

 

2v2EjjcqnxAnAAS.jpg

 

 

Using scraps of styrene the hole was filled ...

 

2v2EjjcFqxAnAAS.jpg

 

 

... putty was used to fill the smaller divots ...

 

2v2EjjcdFxAnAAS.jpg

 

 

And after the patch was done, I prepped the nose to be scored to illustrate the tiles.

 

2v2Ej2GgyxAnAAS.jpg

 

 

It was easier to score 'em by hand. Yes, they're outta scale a bit, but, they're close enough for me.

 

2v2Ejjc5yxAnAAS.jpg

 

 

Starting to add decals ...

 

2v2EjjcL2xAnAAS.jpg

 

2v2EjjcWvxAnAAS.jpg

 

2v2EjjcGUxAnAAS.jpg

 

 

Then glued on the Payload Bay doors ...

 

2v2EjjcCoxAnAAS.jpg

 

2v2EjjchzxAnAAS.jpg

 

... and it's just about done ...
