Title: 1/72 Bandai Y-Wing
Post by: scottminium on March 29, 2018, 07:48:49 pm
In the turmoil of the shift to civilian life after 30 years in the Navy, gotta keep building to keep my sanity!

For some crazy reason I have decided to light the engines and cockpit of the "Wishbone".  While the engines have sorted themselves out I am quite at a loss as to how to take on the bridge.  Small spaces, no sealing means FO, but there is really very little room to work.  More to follow, and if you have ideas about the cockpit, I'm all ears!

If you're going for the cockpit to be lit, I'd suggest the Green Strawberry (http://hdamodelworx.com/Photoetch-for-the-BTL-A-4-Y-WING-Starfighter-172-Scale-Bandai-Model-Kit-by-GREEN-STRAWBERRY_p_395.html) photoetch set.

@Greg, that's a really cool mod...but how was it lighted?

Wiring up the engines requires a carefully thought out plan.  After doing a whole mock up, the engines were drilled out to allow light, the engine mounts were drilled allow wires, and the main part of the engine was 'snipped' as needed to allow for the wires to pass through.  On the starboard side I did a little better and simply drilled out the engine part so the wire assemblies could be passed through.  Once the part with the LED was secured, some gorilla glue was used to lock everything in place.  Next will be the main engine assembly around the wires, modified as needed to avoid crushing the wires.

In the last pic, the little blue spot/hole is where a hole was drilled through the aft portion of the wing strut to allow for the wires to pass.

Next up, modification and assembly of the main engines and wing struts.  After locking in the LEDs with gorilla glue, the engine and strut internals were modified to allow room for the wires.
First, the struts (wings) were cemented together and a hole drilled through the trailing edge (the round part). 
Next, the four parts of the engines were 'snipped to make room for the LED leads and wires. 
Then the parts were assembled up to the point of the last quadrant, the wires run through the body, then part of the 'snap together' was removed and the last quad assembled. 
Finally, the wires were run through the struts and cemented in place.
As always, light check before and after every step.  So far so good.

Next up, main body assembly after running wires for the cockpit/weapons.

Well, it's a photoetch set. Use it in the cockpit and have light shining from behind it through the holes. Perhaps create a light tunnel to have only an LED or three bounce the light around to light up all the holes. Last year I bought some transluscent clay called Sukeru-kun for that purpose, but I have yet to use it. It's sold here in Japan, and you can buy on on HLJ.

OMG, Scott! How did I miss this? Apologies!

My first thought is "Wow! That is TINY!"

Second thought "Congrats on the "shift to civilian life"!" It is a mind-set change, a paradigm-shift of culture but I am sure you will successfully make the transition!

Is this a career change (military retirement to civilian job) or is this retirement retirement - fishing and lawnchairs; or in your case Modeling and Mag-lights? If you wanna share - just curious.

Okay, back to the model: Lighting the cockpit - wow! Just a thought. Place either a FO or a single, small, white LED behind the panel and paint clear colors on the panel to change the light effect. Iain did that once on one of his Star Wars builds and it came out awesome. You may consider duping the cockpit in clear and light block it to get the look.

Good luck on this one! Can't wait to see your solution for the base!

thanks for the ideas gents.  After some research I've decided the light box idea will work, but it's going to be fun using a bunch of SMD LEDs in such a small space.  I've also decided this one is going to be my first jump into the Arduino, so if the resistors are going to be internal to the model, as is my typical practice, I'll have to commit to a voltage plan before assembly.  The engines were already wired up for 9V, so I'm not sure they will work for 5V.  Easy enough, they'll just be directly powered to come on when the power is switched on.

Clearance is pretty tight in the pilot house/gator-cobra head, and with what looks to be 7 LEDs in that area (unless I find a more elegant solution), they will need to be wired together to reduce the number of leads . 

Best of all, the wires have to be run through the fuselage before any assembly can happen there, so the wiring has to be 'final' or over-the-top in order to support the future lighting.  More thinking to do.

@Steve, this is retirement phase 1, where I leave the Navy and still plan to work.  Phase 2 is just hobbies and travel, and that's still some years away.

Oh maybe not lightboxes....
First pic shows how the FO is run for the cannons.  The FO was held in place and hit with the heat gun. The lower half shows the holes for the proton torpedo launchers

Second pic is how the torpedo launchers will be lit.  A fat piece of scrap was drilled big enough for both launchers, and smaller on the aft end to allow passage of the SMD LED.

Third pic is the tiny SMD LED.  About the size of a pen ball.

Fourth pic is emplacing the torp launchers.  A piece of sprue was cut with a drill bit for 1) the SMD (aft end) and a .020 FO stub on the forward end.  Once guided through the hole, the FO was bent with a heat gun, then carefully trimmed.  The SMD and FO were cemented in place, then clamped in place and cemented to the hull with gorilla glue.

Next up, using FO to light the cockpit dashboard.

I assume you will put in a blinking red LED to fire the lasers?

Very nice work Scott! Those cannons look huge in the pictures, but I know from my TIE fighter they are tiny and skinny. Drilling those out had to be loads of fun.

I highly recommend getting your SMD LEDs via Ebay.  You can get the pre-wired.  Also realize that there are a ton of different sizes, not sure what sizes you might need, but there are a ton of sizes, outside the typical 1206/0805 etc.

Loving the build!  I so want to get a set of these 1/72 models, maybe next year, LOLOLOL.

Cheers,
James

@James, that's just what I did, pre-wired on Ebay.  I cannot imagine trying to wire up the LEDs myself.  They'll be attached to longer runs of wire wrapping wire for the trip outside of the hull.

Next up is running the FO for the cockpit lighting.  That's gonna be fun.
Title: Re: 1/72 Bandai Y-Wing
Post by: scottminium on April 12, 2018, 05:01:23 pm
@Greg, the plan is to use pushbuttons to allow firing the cannon and torpedoes separately.

In case I haven't mentioned, I'm a submariner by trade.  My avatar is from a 'coup counting' exercise a few years back.

In today's saga, the wires from the two engines were soldered together to reduce the total number of wires exiting the hull (from 8 to 6).  These were soldered, sealed with liquid electrical tape, then pushed into place, then the two hull halves cemented together (with four wires still to be connected to the cockpit), then the four pieces added that allowed the engines to be connected. 

Kind of a lot to do before you can move on, but now the rest of the hull assembly and the cockpit can continue.  As always, light check after each step to be sure things are still working.

next up, running the FO to light the cockpit.

Post by: scottminium on April 16, 2018, 03:41:48 pm
After putting together the main hull I was able to enjoy a lot of fun work and assembly by adding in most (all but 5) of the pipes that are really the identifier of the 'Wishbone.'  Below is a closeup, along with a comparison shot.

Been working on the cockpit and pilot.  The FO for the 'dashboard' will have be run -after- the bit is installed in the gator head.  This will be a bit tricky but I've go an idea.  Then there will be the close area soldering and slow pulling back of the wires as the gator head is mated with the main hull.

Drilling holes and running the FO for the cockpit.  The larger holes are .02mm while the smaller ones are .01mm.  After running the 0.02mm, they were bundled in a straw, clamped in place and heated to bend them as needed.  Next two shots you can see how they will be pushed into place once the rest of the FO is run.  Last shot is of the last of the tiny FO.

Post by: scottminium on April 19, 2018, 05:40:14 pm
In this pic you can see everything wired up before final assembly.  All the negative leads were soldered together, while the canopy lights, torpedoes and cannon each had their own lead.  These are the four wires you see leaving the 'gator'.  I tried to gently pull the red and white wires back as I positioned the two halves, but I was only partially successful.

Upon testing the torpedoes don't work. I must have separated the red wire.  :( 

The cockpit lights and cannon are good, but now I have a dilemma.  i was going to use a Nano and enable firing the cannons and torpedoes, but now all I have are the cannons.  I think I'll still try to get those to work so I get some Arduino programming experience.

By Odin's Beard, those are small fibers!

I'm surprised that I didn't read somewhere that you broke a few bits! Good job!

Quick question about the white gorilla's glue you have been using - have you noticed it NOT bonding to the straw through which you bundle the FO?

I have been having an issue with that and wondered if it was common or if I am doing something wrong.

Keep going, Scott!

Enjoying the build!

@StarSiege--it does not always feel so....

@MSgt--Steve, I haven't had trouble with gorilla glue (not their CA, their main line) bonding with anything.  Provided it has a rough surface or something it 'likes' it sticks like the dickens!  Gotta be careful at what you let it get on.  In this case the things inside the 'gator head' just needed to stay in place long enough for assembly, and after that it didn't matter.  In other applications I build a little styrene box and then the gorilla glue is used to fill the voids.  As it expands quite a bit, that locks everything in place.  That is probably why it works on the straws--I put a little gg in the right spot, add the straw, add a little gg, then tape over it to dry.  The gg fills up everything and the straw cannot move.

I've decided to still try my hand at the Arduino on this kit just to get the practice before I try something more daring!

Cockpit lighting before and after shots.  The tinting for the indicators was done with sharpie on the other end.

A little bit of weathering to highlight the incredible details built into this kit.  Once the engines are snapped in place I'll hit it with some faint gray shading, add some carbon scoring and then seal it.  Lights will have to wait for the arduino adapter to show up.

I've read that painting the pipes separately before attaching them to the fuselage requires extra care because when paint finds its way into the holes and on the locator pegs, it causes the fit to tighten up too much and can lead to problems.
Title: Re: 1/72 Bandai Y-Wing
Post by: scottminium on April 25, 2018, 07:22:19 am
@Greg, yes, the tolerances for most of the pipe connections are very close (like the rest of the kit!).  If you want to add any after assembly you need to be very selective as sometimes the sequence of assembly may preclude adding them later.  This is true of most of the pipes that seem to go from the fuselage to the cockpit.  I picked five that looked like they could go in later, and painted those the rust color.

Post by: MSgtUSAFRet on April 26, 2018, 07:40:20 am
Scott, this is coming along nicely!

I really like the wash you put on it! I am gathering parts and knowledge for a TOS Galactica build and this is something I think I will have to do to get it to look right.

Are gonna paint the R2 Unit a little? If so, what color - red, blue, pink, chartreuse? Either way, its a fabulous build!

May the Fourth be with you!

@Steve, I decided against chartreuse, but only because I didn't have any.  :-\  First is a closeup showing the colors for the astromech and the pilot.  Second pic is of the painted base with the modified mounting part.

Next will be final pics with the canopy and scoring damage, then lighting once my last arduino parts arrive!

Scott, I hate it when you don't have the right colors to match your ensemble! :D

The droid looks good but I am even more impressed with your pilot! That must have taken a while and not a few minutes under some powerful loops!

Carry on and congrats on the retirement!

Thanks Steve!

Reminder to self: always put the resistors inside the model.

After already severing the torpedo wire, today while goofing around I got ahead of myself and connected the snake head lights without resistors.  The white one survived, the cannon LED did not.   :'(

The cockpit lighting and flickering (somewhat) engines look great, but no weapons.  Soon to finish up and post glory shots!

Excellent work, Master Jedi!

I'm beginning to think this isn't anything you can't build, Scott! Glad the cockpit control panel worked out. It looks awesome!

Love the piping! (Hummm...sounds like I'm talking about cake decorating!  ;)  )

The weather looks great, too! R2 looks okay. Still would have preferred Chartreuse, but since you didn't have any...   ;)

Seriously, good job, Scott. Have you posted any shots in the Modeler's Gallery?! This would make a fine addition!

Keep going!
