Pat creates the iconic Apollo Command Service Module, a lengthy project but well worth the wait.

I've started on another vac-form project for MMM and his crew.  This is a picture of two of the masters ready to have melted plastic sucked over them.  A classic Marvel "No-Prize" for figuring out the final product.

Alright, now that the cat is out of the bag (and since there is no basketball, baseball, hockey, soccer, NASCAR or competitive knitting), I thought I would share some of the details of how I go about making my current vac-form project: the Apollo Command/Service Module.  

Whereas our friend Amaury spends months painstakingly making every piece of every model/toy by hand, most of the time I spend is involved in designing and creating the masters that allow me to make multiple copies.

Design starts with scaling down drawings of the real thing to the Major's size.  For instance, the SPS engine shown yesterday is 7-5/8" tall and 8-3/8" diameter at the bottom.

I cut multiple disks of blue insulating foam and glue them on a spindle that goes into my drill press for turning.  The shape of the "bell" is cut from a piece of wood to make a shaping tool.  The edge of the tool is covered with sandpaper and pressed against the foam as it turns.  Once the desired shape is achieved (and all of the dust is cleaned up), the foam is covered with aluminized tape to protect it from the heat of the melted styrene.

Apollo CSM Update #2 (no restaurants OR bars, are you kidding me?)
The scaled diameter of the Service Module (SM) is 12-7/8".  It will consist of a sheet of styrene wrapped around interior bulkheads.  I cut a disk out of wooden board.  One board can be used to make three different bulkheads: a plain flat one, one with a 6" hole in the middle and one with the engine mount.  

The master for the engine mount at the rear of the SM was made by gluing pieces of blue foam board and then shaping the edges with a sandpaper covered tool.  The pictures show the before and after.  The foam is covered with Alumiized tape and the assembly is set on the bulkhead master for vac-forming.

Because the major parts of this build are all round, I built a 16" diameter round frame to hold the styrene.  This spreads the pulling force evenly and prevents the wrinkles that a square or rectangular frame would have.

Apollo CSM Update #3
Moving on to the Command Module (CM).  The diameter of the CM is also 12-7/8" (same as the SM).  Using the same techniques as before, disks of blue foam are stacked up and glued together.  Unfortunately it was too big to turn in my drill press so I had to improvise with my hand drill.  Using another sandpaper covered tool, the foam is turned down to the final cone shape. 

An Exacto knife and Dremel were used to cope out the docking tunnel and the notches for the rendezvous windows.  The foam is covered with Aluminized tape (which makes it look like the real thing).  The final color of this model will be white like the Apollo's used for Skylab (or Ironman One in "Marooned").

The shell is vac-formed from a 16" diameter piece of styrene.

Apollo CSM Update #4
Even before vac-forming the capsule, I realized that the size of the actual hatch would be too small to access the interior to get the astronauts in and out so I cut a larger access panel.  The panel is held in place with a series of tabs.  The actual crew hatch will be a decal on this panel. 

Beveled foam disks are glued inside the styrene shell to reinforce it and provide the ceiling and floor of the cabin.  There are numerous pictures and diagrams of the interior but I found the ones below to be the most helpful.

At this point I had to decide how realistic and detailed the interior would be.  This would determine what the seats and the control panel would look like.  That will be in the next update.

Apollo CSM Update #5
The real CM had a removable center seat that allowed access to the guidance & navigation station and the lower equipment bay located under the seats.  I read somewhere that the Apollo astronauts really liked that there was enough room to stand up in the CM so I decided to include the lower equipment bay (LEB) and made all three seats removable to access it.

The seats are held in place by two rods.  One rod is stationary and the other is spring loaded.  Notches under the seats engage the rods.  The seats slide sideways to help get them in and out. 

The walls of the LEB are covered with decals that are simplified representations of the equipment that lined the real thing.  The control panel is represented the same way.  Some of these are difficult to see in the assembled model but they are there.

Apollo CSM Update #6
The previous five updates have summarized the progress made over the last 12 weeks.  Now we are in real time.

Here are pictures of the first time the different pieces have been put together.  As you can see, the CSM is quite a bit larger than the original Space Station.  There will be a removable door in the same place that the SIM (Scientific Instrument Module) bay was but it will be larger.  This door will allow access to the interior of the SM.

There still a lot of work to do (RCS quads, painting, decals, etc.).  Stay tuned.

Apollo CSM Update #7
I promised some pictures of the astronauts through the windows but this video shows them better:

Apollo CSM Update #8
Baby steps.  The RCS thruster quad "boxes" are made by laminating three pieces of fiber board.  There is a countersunk machine screw in each one that will allow the thruster assemblies to be removed from the SM shell for shipping.

Aluminum angles have been added to the edges of the SM shell where the door will be to keep them from warping.

The SM shell has been drilled to install the quad boxes.

16 RCS thrusters vac-formed and painted. 8 attached to the quad boxes.
Also working on the SM access door.

Apollo CSM Update #10
The distance between the top and bottom bulkheads is right around 12".  I thought about putting another bulkhead right between them for a "two story" space but 6" isn't really enough headroom.  I decided to install six 4" fuel tanks on the bottom bulkhead and put a deck right above them.  The glue on the access door is still curing.

The main engine has been painted flat gray.  The RCS quads have been temporarily installed.  The engine and the thrusters are removable.

This is what our kitchen looks like AFTER the Friday cleanup.  That's a painting my daughter is working on.

Apollo CSM Update #11
I shot some videos of the CSM on a display cradle.  The engine is held in place by magnets as is the side panel.  As I mentioned, before, the RCS quads (thrusters) are also removable.

The gray patches are radiator panels.  The rest of the decals are crude print outs taped in place.  

The interior of the SM will have some additional details/decals.  There are some LED lights behind the control panel that are not lit in the video.

Here are the links to the videos:
 


Getting closer to finishing.
Hope everyone is staying safe!

Here is a picture of the 1/12 Lunar Module from 2003 docked to the 1/12 Command/Service Module from 2020.

Here is a short video of the internal lighting of the CSM.  I wanted push button activation instead of a toggle or slide switch.  The battery and circuitry are inside the SM and the push button is located on the side opposite the SM access panel (no need to open anything to turn the lights on.  The lights come on and then slowly dim to off after about a minute. Three LED's behind the main control panel and one inside the SM.  The lights are activated with a push button and slowly dim to off with a transistor and RC circuit.

Apollo CSM Update #12
Added exterior details including the umbilical housing (opposite the main hatch); the red, green and yellow rendezvous lights (painted wooden dowels); and some panel striping.

Also added a program/mission insignia to the SM panels and the cradle.  This is ‘borrowed” from the Apollo 15 mission patch.  The three red, white and blue arrows/wings seemed appropriate for our guys.

I wanted to add some original MMM pieces to the CSM.  Since this is not a lander, I chose the Satellite Launcher.  The SM bay contains four satellites for launching and a Jet Pack for retrieval if needed.

While Mason and Storm monitor progress in the CM, Long prepares to launch a satellite from the SM.
