50th Anniversary Saturn V Build Update 9

Well it’s time for another update.  I’m down to the painting now.  This is the slow part for me.

I started by masking the S-IVB and S-IVB interstage.  I’m not going to mask all the small antennas on the IU.  I’ll paint them individually after the black goes on.  The S-IVB interstage has a couple of sections of black/white that are divided by a horizontal line.  I’m using Tamiya flexible tape for that.  It can follow a gentle curve without making creases in the tape.

The F-1 engines have been painted with Tamiya Metallic Silver.  The inside of the bells has not yet been worked on.  You can also see that the S-II and S-IC have received their coats of white.  Some of the black details on the S-II will definitely be done with decals.  Trying to smoothly mask around some of those details would make me crazy.

Here you can see the S-IVB and interstage with their black paint.  The Tamiya yellow tape covered the stringer sections very well.  I didn’t have any seepage under the tape.  The SM still needs to be foiled.  I guess I’ll be doing that next.  You can also see that I’ve added the silver S-IVB APS pods.  To the left of the S-IVB you can see one of the fins for the S-IC.  They have been painted and will be installed after the S-IC gets its black and silver details.  You can also see the SM RCS quads.  These are from the New Ware set.  I tried to use the ones that came with the RealSpace Spacecraft update kit, but I broke off a couple of nozzles.  Glenn had the pour plug attached to the quads at the nozzles which makes removing them from the pour plug challenging.  Tom at New Ware attaches them to the pour plug at the quad housing instead of the nozzles.  Hopefully I’ll get them off the pour plug in one piece.  At least I’ll have 8 chances.  New Ware included 8 and I’ll only need four.  I’ve included a close up of the RCS quads.  You can see that New Ware even hollowed out the nozzles a bit.

That’s it for now.  More masking and painting to go.  This is my least favorite part of model building.  There are so many ways to mess up a model at this stage.  In the end it usually ends up looking good, but it is a pain getting there.

More to come…

50th Anniversary Saturn V Build Update 7

Time for another update.

I’ve been busy on the Apollo spacecraft section.  The Realspace part needed a few updates.  The first one I tackled were the panel lines on the Spacecraft Lunar Adapter (SLA).  Glen had engraved the lines, but my sources indicated that they were raised lines.  They were part of the separation mechanism.  The New-Ware update set had some PE parts that could work to update it, but when I checked, I couldn’t be sure that they would fit properly.  They would fit better on the Airfix part but that presented its own problems.  If I used the Airfix SLA then I’d have to cut off the Command/Service Module (CSM) from the Realspace resin part.  I could keep the Airfix Service Module (SM) but then I’d be in a pickle for the Command Module (CM).  Both the Airfix and Monogram CMs were wildly undersized, even with the kit Boost Protective Cover (BPC).  So, I decided to add my own panel line strips to the resin SLA.  I also had to add the semi-circular parts that were between the hinge details.  I found that a 1/8 inch hole punch made a circle of styrene sheet that I could modify and make look good enough.

I then got ready to add the PE parts to the spacecraft section.  My drawings show that after Apollo 14 there was an extra window in the BPC above the commander’s docking window.  I took a small drill and made an appropriate sized hole.  I’ll paint both the windows black when it comes time to paint.

I started adding the PE with the CM attitude control thruster covers.  After adding the first one under the crew hatch, I went to add the next cover and noticed that where the other two covers needed to go was a reinforcing ridge.  I could have just moved the thruster covers over to avoid the detail, but that would have put them obviously offset from the +Y and -Y positions where they were supposed to go.  I removed the offending details and used some .4mm strip to place them where they were supposed to be.

Next was to start adding the PE to the SLA.  The PE pieces were relatively large so I used a dowel to add a gentle curve to the parts so they would conform to the curve of the resin.  One thing I fortunately noticed before I started adding the PE parts was that New-Ware labeled the placement drawing with POS III in the wrong place.  I was comparing to my source material and noticed that things were not going to line up.  It took me a while to realize that the fix was as simple as just re-labeling the instructions to show POS I where they had POS III. Things went smoothly after that.  I’ll add the SM attitude control thrusters after painting is done.

Now all the major sections are ready for their first coat of primer.  Then I’ll be able to tell what areas need further attention.  I still have to finish the Escape Tower.  I’m trying to decide if I want to use the Realspace PE parts or if I want to scratch build one.  The escape rocket from Realspace is fine, I won’t need to mess with that.  I guess I’ll play with some styrene rods and see how difficult it might be to scratch one.

Things have finally started to warm up.  I’ll try to get some primer sprayed now.

50th Anniversary Saturn V Build Update 2

More progress has been made on the Saturn V build.  I have removed all the raised detail from the aft skirt heat shield.  That all had to go in order to install the brass part from New-Ware.  The brass part is very nice and has much better detail that what was on the original piece.  After removing the raised detail I got to thinking about how I was going to mount the model on its wooden base.  I have used steel rod in the past and that works well.  All I have to do is figure out how to accommodate the rod in the base of the model.  I am using 1/8 in brass tubing and that will slide over the steel rod that is in the base.  I used some paper tubes and epoxy to cover the hole where the center engine will be mounted.  After epoxying the tubes in place and filling them with epoxy, I drilled an 1/8 in hole from the center engine through the tube and out the top of the aft skirt part.  I then used JB Weld and put the 1/8 in brass in the drilled hole and about 3/16 in out the bottom.  The extra out the bottom will aid in mounting the center engine.

After doing that I decided that having a 1/8 tube projecting from the heat shield would be a great way to mount all the engines.  You can see the 1/8 in plastic tubes that I epoxied in place for each engine.

The pictures show the rescribed ribbing where I sanded the hump down.  You can also see that I have started adding some of the photo etched (PE) details to the aft skirt.

50th Anniversary Saturn V Build Update 1

My New-Ware detail set came in, so I’m getting back to the Saturn V build.  The resin detail parts are very nice.  I’ll be using the batted F-1 engines that came with the New-Ware set.  As far as the aft skirt goes, I’ll be using the resin air scoops that are on the engine fairings.  I looked at using them as is and removing my sheet styrene additions, but I don’t like the way that they are modeled as recessed parts.  They were not recessed on vehicle, they were actually on the outside of the skirts. (Update: They actually were recessed, but they also had a raised section of scoop that is not on the New-Ware parts.)  So I cut the scoops out of the part and discarded the rest.  I will be using my styrene add-ons after all.  I will then attach the air scoops to my styrene additions.

The pictures show most of the resin parts and how nicely they are molded.  There is a fret of etched brass that has many more details on it.  I’ll post a picture of those soon.

The Airfix aft skirt has a very noticeable bump on the mold lines.  I really want to get rid of those, so I have sanded that section of the aft skirt flat, and I’ll try scribing new ribbing in those areas.  I really don’t want to sand off all the ribbing and try to replace it with styrene strips or scribing new ones all the way around the skirt.  We shall see how it goes.
