Title: Battlestar Pegasus - Moebius 1/4105
Post by: scottminium on January 12, 2019, 07:31:58 am
Hello all and Happy New Year!
I was going to hold off posts for the new board, but since everyone else is still going...

Next project is:

Overall fit of the pieces is somewhere just short of amazing.  A few spots will require work, but just about all the big obvious joints are nearly perfect.  Great engineering with this kit.  The one area of concern is in the mounting of the flight bays, but I'll get to that.

Up first is some work on the sublight engines.  The first pic shows the fit OOB.  They seal up nicely but are sprung a little.  So, they were clamped in place and cooked in the oven for 15 minutes (175F).  Out of the oven the second pic shows they are much better aligned.

Next was to open up space for wiring.  A looksy at the attachment points shows a nice place for a hole.  First drill the hole in the main hull with a 1/8" bit, then use that as the pattern for where to drill the engine pod, then repeat 7 times and open up to 1/4".

Scott,

I'll be keeping an eye on this build as well. I've got one of these in my stash as well along with the
 aftermarket resin pieces someone was offering when the kit first came out. As Dave said you don't see too many of these built here. Looking forward to seeing this come to life.

Thanks for watching!

Something interesting about Pegasus is that there is a lot of spot light kind of lighting, where you kind of see the light, but mostly what it illuminates.  I'm trying to go for that in a couple of cases with larger FO.  In another case, the marquee lighting for the registry, some SMD lights will be used with a tiny custom box.

Lastly on this note, word of warning, there are a lot of LEDs in this build, and way more FO.  All of the launch tubes are detailed into the area between the landing bays, and that alone is 41 per side.

With unguided lighting projects I find myself regularly having to think and rethink how to get light to show up at a certain point.  How will the wires get run?  Use FO or not?  Will the wires fit?  Where do you cut the holes for the wires?  What will keep the lights in place?

-First up here is a burn in run to test the lights.  I usually go overnight.  Interestingly, I've yet to have a failure.
-Next the flickering white engine LEDs and the clear inserts were painted blue.  In retrospect I should have just added more resistance to dampen the brightness.
-Then all the engine halves are light blocked.  Note that the aft guide pin is cut out to give a clear shot for the light.
-To keep the LED aligned at the 'exhaust', small platforms were built with strip styrene.  Note the small piece on top that will be a guide with the leads from the LED.

Post by: scottminium on January 13, 2019, 02:49:18 pm
Next, 8 sets of lights for the engines were soldered up.  There is one flickering light, painted blue, and one white light for a couple pieces of FO. Testing showed the lights were still really bright, so some Tulip was applied to the LEDs directly.  The red and black 'goo' on the wires is also Tulip for insulation.  Cheaper than 'liquid electrical tape' and it has no smell.

After test fitting and bending as needed the light assemblies were locked place with 1) a small piece of styrene locking the blue light, and 5 minute epoxy for the straw holding the FO/white light.  Cotton was stuffed in the straw to help tamp down light leaks.

Finally, I still had problems with excess light....when it occurred to me that I didn't need to block the light, just make it blue.  A little tape, a little glue to keep in place permanently and voila.  Which is french for, and then I found out.

Scott, this is looking familiar - as in your TOS BSG!

This has become the most fun of a build for me; figuring out the lighting.

...and voila.  Which is french for, and then I found out.

Keep going, Sir! This is gonna be fabulous!

@Steve, thanks, but I did a BSG reboot, not the original.  However, Pegasus was actually designed to look more like TOS.

I too find lighting challenging and fun, but wait till you see the landing bays.  They are going to be scary!

Nice one Scott - you might convince me to finish the one I started 3/4 years ago. I bought the PE set after I failed dismally at making my own hangar walls: http://www.arcforums.com/forums/air/index.php?/topic/282230-bsg-pegasus/&tab=comments#comment-2687621
You can get a cool lighting effect by thinning out the back walls of the engine pods and some of the body and put an SMD right behind it - holding it there with hot glue.
Got any ideas on how you're going to tackle the body paint? I was thinking for mine a light base coat of maybe dark or neutral gray then sprayed with Alclad Titanium to get that metallic look. I'm interested to see what you do with yours

Ah well.

I'll be watching this build closely as well. It'll be interesting to see all the differences between this one and the Galactica I'm doing. Fun to watch!
Title: Re: Battlestar Pegasus - Moebius 1/4105
Post by: scottminium on January 27, 2019, 08:09:01 am
And now for a lot of work on the flight pods. To begin with, even if they were the same size as the Galactica, there are twice as many!

The lighting on this ship is quite different than Galactica, and some of the effects I decided not to attempt.  For the marquee lighting of the registry, I came up with another idea.  The first pic zooms in on the registry and shows a bit of detail that needed to be removed.  The green marks are where .02" or .03" FO will be used for highlights.  BTW, the lowest ones turned out to not work because there wasn't enough room, but I'll try to show that later.

The next pics show the detail sanded down and the 'light box' that was built (x2) to get the marquee lighting effect.  After match marking the light box to the flight pod, holes were drilled for SMDs.
Title: Re: Battlestar Pegasus - Moebius 1/4105
Post by: scottminium on January 27, 2019, 08:11:05 am
To finish up the marquee lighting modifications:
now the lightbox is placed and the SMD tested.  Still working on getting the resistance correct.

Next up is lighting the landing bay approach lights and all the inside work on the pods.

Post by: MSgtUSAFRet on January 28, 2019, 08:05:47 am
Scott, that is a very ingenious idea for lighting the marquee. Well done!

Will there be two lights for the marquee or just the one?

This is looking good. Keep at it!

Steve
Title: Re: Battlestar Pegasus - Moebius 1/4105
Post by: scottminium on February 01, 2019, 05:22:25 pm
@Steve, there are two lights per marquee. 

For the upper flight pods, looks like minimum 1 red, 1 green and 1 white LED in addition to the 2 SMDs. 
For the lower pods, same thing but no SMDs. 
Of course, what I have not figured out yet is where the launch tube lights will be.   :P

More pictures soon.

I tend to work several sections at once, always waiting on this to dry or that putty to set or something.  But I've decided to hold off on posting until I can complete a section so it tells a better story.

The bow section consists of two major assemblies, upper and lower.  There are also recessed parts for both.  They required a small amount of body work after installation.  While there are some standard 'windows' on 'The Beast', these are only in the trench of the upper section.  There are also lots of 'spot lights', and large diameter FO will be used to try and get that effect (with varying amounts of luck).

First up is the lower section, which has some internal lights, but the part that goes on top of it also has some of those 'spot lights'.  This results in having one batch of FO having to be squeezed into the other section.  As well, the thick FO needs to be bent with a heat gun and even that does not keep it under control.  AFter getting it where I want it, I clamp it and bake at 170F for 20 minutes.  everything settles into place.
Title: Re: Battlestar Pegasus - Moebius 1/4105
Post by: scottminium on February 10, 2019, 08:11:12 am
The upper section has a mix of large and small FO, so the large goes in first.  Although this is easier, it also means playing 'Operation' while running the smaller stuff.  I had thought to put the large FO in a couple of other places, but the lower panel sealing up the upper section resulted in no clearance.  :(

Four LEDs were used, with different resistances to give different brightness (with the thick spot lights being brightest.

After determining how the wires would get out of the bow section, it was all fitted together (which was great but not perfect) and baked to ensure the alignment was as close as possible.  Why?  Because the upper and lower sections are not mated to the main hull as one unit...

And now these two pieces can sit on the shelf for a bit while the landing bays are worked.

Hey Scott,

This is looking great and, as always, your work keeps challenging me to raise the bar with my own work! :)

AFter getting it where I want it, I clamp it and bake at 170F for 20 minutes.  everything settles into place.

I think I understand the concept, but the actual visual image escapes me. What clamp did you use? The quick clamp? The heat doesn't affect the clamp?

After determining how the wires would get out of the bow section, it was all fitted together (which was great but not perfect) and baked to ensure the alignment was as close as possible.  Why?  Because the upper and lower sections are not mated to the main hull as one unit...

Again with the "baked"! This seems like a technique I should have used on the Protector. So clamped again? What did you use as the platform to support both the model and the clamp? Wood? 2 x 4 block?

As always, keep going! I am learning alot and seeing the skills I need to develop!

So Say We All!

Steve

Post by: scottminium on February 13, 2019, 06:06:33 pm
So, more on the clamping and baking.  Polystyrene, to include the stuff I use as FO cable, becomes flexible somewhere around 170F, but it is far from melting.  The really thick parts don't tend to bend much at that temp, if at all. 

let's say you have five parts (upper bow, upper bow plate, lower bow, lower bow plate and the connecting piece.  When you fit them together they are OK, but require a lot of pushing and prodding to get alignment.  To fix this, put the whole mass together and clamp it in place, but with _just_ enough pressure to make it align correctly.  THus, when the softer bits soften you are not pushing them any further. 

Sit the contraption on a cutting board and stick in the oven.  I put it to 170F and hold for 1min after it gets to temp.  Take it out and let it cool.  If you did it right, when you release the clamps there is no movement.

When it comes to FO, the thicker parts are hard to get into position, and you don't  really want to force them into position when you are doing final assembly.  One solution is the press the FO into places you want it to lay, hold it there, bake it and, voila, they stay in position.

I'll dig up some parts to demonstrate the whole process, maybe with a couple videos, but trust me it is harder to describe than to do it.

Best of all, let's say you have some slightly warped pieces (check the recent galactica build!), you can use this technique to gain much better alignment and less putty.

Thanks, Scott, for the detailed explanation!

Thanks again!

And now for the continuing saga of the landing bays (or flight pods, whatever floats your boat)
Pegasus has 2x the flight bays, rather an "in your face" demonstration of their control of gravity as the lower one is inverted...But this means you have four flight pods to finish rather than Galactica's two.

Having decided to add lighting accents to the marquee, the landing lights (port/starboard), and highlights along the hull, this led to quite a bit of FO as well as LEDs.

a mix of .030", .020" and .010"  FO were used.  Rather than just open space, the kit includes perspective decals for the landing bays which you can see in these shots.  I attempted at first to use .060" FO to illuminate these, so you can see them in a couple pics. (the really thick FO) But in the end they didn't illuminate well, so I replaced them with SMDs.

So first up, adding the running lights for the landing bays.  The issue here is the angle of the surface.  Solution: drill down to give you a flat surface to drill into the flight pod.  Then, insert FO, apply putty, remove FO, sand putty.  Sheesh!
Title: Re: Battlestar Pegasus - Moebius 1/4105
Post by: scottminium on February 14, 2019, 08:10:34 pm
Next on the pods, the landing strips and interiors were painted gray, then holes were drilled for the running light FO as well as the large FO (which would later become SMDs).  Then the perspective decals were applied.

For the landing decks, the square holes for rail guns need to be filled as they go all the way through to the visible part of the landing area.  Filling them ensures the decals look smooth, and the rail guns will be mounted without the square alignment piece.

I have seen one build of this kit where the landing strip has deck lighting....I have absolutely no idea how they did that.

OK, seriously this weekend I'll post new pics.  The flight pods, or landing bays, or whatever you want to call them, are truly a tiny little piece of sweet hell.

The lower pods have 5 LEDs, the upper pods have 7, and then there is the need to connect the two.  Oh, did I mention the tween decks area where the launch tubes are located?  These have 42 pieces of FO, one SMD, and literally, oh, .05" of height to work with...and then you have to exfil the wires. !   

All that said, damn do they look sweet.  Or, they will when they are done.  Ok, enough whining!  Back to the salt mines!

That's what we're here for; to listen to the whine - cause we've all been there!

It will be worth the work and, how did you put it "sweet hell", you have to go through in order to get the look you want.

Stay strong!

<cracks knuckles>
Here are some shots of the landing bays in progress.
In the first you see the rats nest after running all the wires and sealing with clear epoxy.  Later I decided not to use clear epoxy because it really doesn't fill gaps like gorilla glue.  If you want to use epoxy you need to score nearby surfaces to give it something to grab onto.
In this picture you also see "BOX" written down.  Rather than try to pull all these strands into a straw as normal, instead they were routed to a light box and illuminated with an SMD.
The second pic is the sides of the 'box', and the third shows what it looks like.

Post by: scottminium on March 13, 2019, 05:42:21 pm
And now for a demo of what 'baking' can do for you.

First pic you see all the FO strands bulging out.  While they could be left like this, that runs the risk of something getting pinched or out of place when you go to seal them up.

so, take a piece of plastic junk and tape, clamp the strands in place and bake at 170F for 20 minutes, cool, and remove the clamp.  In this case, I used this type of clamp so that things would not get compressed any further.

After cooling and unclamping everything stays put.

Final work on the upper part of an upper pod.  You can see the tails for the two marquee SMDs.
It turns out my 'elegant' solution for the red and green running lights didn't work so well, so I had to add two more lights. 
The test photos here are before I fixed those running lights, so the red ones are a little dim.

I like the lighting for the entry ways, though the decals don't mesh up quite perfectly.
Title: Re: Battlestar Pegasus - Moebius 1/4105
Post by: scottminium on March 13, 2019, 06:38:19 pm
And now for the launch tubes.  The tubes are located between the upper and lower landing bays, with 42 total.
Drill the holes, route the FO.  First I used .020", but it was too rigid to bend as tightly as you will see is needed. 
Secure the FO with tape so they exit straight.  Glue with gorilla glue, taping on top so the glue stays below the lip.  The recess is .03" tall.

bundle the FO and move toward where the light box will be.  The light box is .02" tall, but considerably wider.  Don't worry, I used to bullseye womprats in my T-16 back home and they weren't much bigger.

Cut FO, shove into lightbox.  The tiny hole is for the SMD.

Post by: scottminium on March 13, 2019, 06:43:37 pm
And as I was mocking up the fit, I found a couple of parts had warped!  Oven to the rescue.

finding a small piece of wood I clamped the errant landing bay and baked it in position.  30 minutes later, unclamped, all good.

Test fittings sat.  Now just the last SMDs need to be placed and all can be sealed up.  WHEW!

Right before I went out of town this week I finished sealing up the flight pods.
-add the SMD to the underside of the flight deck, here is the wiring.
-'butterfly' the two parts and solder the wires together and lock in the SMD with gorilla glue.
-a shot of a lower flight pod sealed up.

Not shown, sealing up the small gaps you see.

-right before assembly the recessed area was painted.  I can -just- get a pair of cuticle scissors in there to snip the FO when complete.

a little more putty and sanding needed on the struts and undersides of the landing bays, but not much.

Up next, the FTL drive exterior, the main hull, and joining it all together.

Scott! I always love your builds as I learn so much about FO lighting techniques! Awesome!

I like the little notes you leave for yourself on the pieces; it reminds me of me! ;)

In pic #4, you cut a small groove to allow the green and yellow wires to pass through to the support, but you didn't cut a channel for wires in the support. I take it you had enough clearance in the support?

In pic #5, do my eyes deceive me or did you paint the recessed areas black or gunmetal grey? Is that for a contrast for the lights?

All in all, this is still an outstanding build!

Keep going and keep posting!

So say...eh, you know what we mean! ;)

@Steve, in pic #4, the "top" of the flight pod mount is open.  Remains to be seen if this will adequately hold the pod on final assembly.  In pic #5, I painted the recesses before assembly for one reason: I wasn't sure if the FO could be snipped after final assembly.  Turns out yes, but it still looks better that I painted it early.

Next up, masking.  The ends of the 8 sublight engines were previously painted with clear and blue from the inside.  A little piece of tape for each protects them from painting.  The flight decks were another problem.  On GALACTICA I used tape, thinking I had protected the landing deck by using clear finish, but 1 out of 4 was damaged.  This time I put paper in place and tried to seal it against the hull with liquid mask.  Fingers crossed.

Next up, gutting out the sealing up of the main hull.  Butterfly the hull, route the wires, seal it up.  What could go wrong?

Fortunately with PEGASUS, a pair of tweezers can save you at this stage.  A little bit of putty and this will be done.

while working on the main hull, the engine nacelles were finished up.  these are actually out of sequence, but here is one with the primer (50% black, 50% grey stynylrez.  (note, this is not very soluble in isopropyl alcohol!)

and then with the finish (so far) of 2/3 steel, 1/3 gold by Vallejo Air.

What is old is new again.  This pic has some interesting history to it.

The container of Testors glue is a new one.  I just retired the old one after -at least- 15 years.
The plastic putty knife was purchased in Jacksonville, FL between 2001 and 2003.
The cuticle scissors were purchased in the last two years.  The brass threaded tube, a week ago.
The tweezers were purchased over 5 years ago, but I cannot say when.
The black wash (Citadel), around 2011. 
The hobby mat, well, before 2005.
The wine opener, probably last year when I lost one on vacation.
The Aztek paint, 2015-2016--when I FINALLY got an airbrush.
The big clamps? last year.
The two things of Vallejo Air paint (steel and gold), 2019.
The butane flamethrower (on model scales), meh, it's a fall back.

Getting close to the end after a few months.
Engine nacelles with 7/9 (haha) showing pin washes. 
Next the flight pods, with one pin wash complete, the other awaiting.
Then the flight pods and bow section painted with the red accents.  A little touch up required but not too much.

For the landing decks I cut a piece of paper and fitted it in place, sealing the end with some liquid latex.
