Here is another view of the struts during rebuild.

Dean,
Thanks for the great pictures. I was hoping I wouldn't have to cut anything (gear door hinge pin), but I guess nothing worth doing is ever as easy as we wish.
Thanks again for the great pics and lessons.

Maybe if you pre-heat the gear door with a light bulb, it will flex out of the forward point without having to cut the pin. May be worth a try.

Removal and disassembly of cockpit

Post by deankleines » Tue Feb 16, 2010 7:39 pm

I have my cockpit completely disassembled for significant detailing to be done.

Send me your e-mail and I will link you to my flickr account so you can see some of the photos.

I can write a step by step procedure for those who wish to take apart the nose.

E-mail me deankleines@sbcglobal.net

Dean,

I have taken the plunge on the ejection seat. Took it apart and sanded off the old pleated cushions and made new ones with 2 Part Epoxy putty. About half finished with the first one. Will post some pics soon.

Mike

P.S. I could use those directions cause it looks like I'll head into the deep end too.

Taking apart the nose section

Post by deankleines » Wed Feb 17, 2010 4:09 am

Mike and anyone else interested in taking apart the nose section:

Not that hard and really straight forward. I will post steps tonight.

I used a Dremel with a grinding bit, a razor saw and lots of care. Everything came apart really easy once I understood how it was manufactured.

It was really exciting to see the engineering that went into this!

Ejection Seat Progress

Post by mcaulk » Thu Feb 18, 2010 2:02 pm

Dean,

Your pictures inspired me to try something new. Check it out. Spent last two days working on the ejection seat. The original pleated cushions were replaced with a more fabric version. (See earlier pics) I have seen quite a variety in colors ranging from tan to olive to a dark green. Taking a tip from chuck540z3 I formed the individual cushions with 2 Part Epoxy Putty. Stuff is great. Once you kneed it together you have about 15 minutes to shape, cut and finish it. After that it begins to harden. Next day you can sand it! Chuck used some sort of medical tape to imprint a fabric pattern. I tried this with mixed results then I thought... "why not just cover the hardened cushions with the band-aid material. So I gave it a shot
and this was the outcome.

Mike

Mike,

Great job on the cushions!!!

Can't wait to see our seats all decked out and ready to "punch out"

Maybe we should put live charges in them!!!

Hope you are having lots of fun!!!!

Dismembering the "bang seat"

Post by deankleines » Thu Feb 18, 2010 5:44 pm

Well - I took the plung and used a flat blade screwdriver to take apart the seat. Came apart fine.

GRU7 Progress

Post by mcaulk » Mon Feb 22, 2010 3:36 pm

Snowed today in Michigan, school was canceled so I worked on the ol' GRU7. Still a long way to go. The stock lower pull handle needs to be replaced (way fat!) A bunch of tubing and wires need to be installed and I have to do this all over again for the rear seat. I'll included some progress pics with more to follow later.

<a href="http://s160.photobucket.com/albums/t197 ... nt=4-1.jpg" target="_blank"><img src="http://i160.photobucket.com/albums/t197/mcaulk/4-1.jpg" border="0" alt="Photobucket"></a>

Flattened the cushions and painted them "Sac Bomber Tan" Actually have uncovered pictures of at least 4 different style of cushions so if you stay away from hot pink you should be ok.

<a href="http://s160.photobucket.com/albums/t197 ... rent=4.jpg" target="_blank"><img src="http://i160.photobucket.com/albums/t197/mcaulk/4.jpg" border="0" alt="Photobucket"></a>

The buckles are a tad small for this scale. They are Eduards 1/32nd scale seem closer to 1/24th. They are way to big for that scale but just a little small for 1/18 but the only alternative was to scratch build a set. I started then contemplated gouging out my eyes but instead chose to compromise until someone makes a set.

<a href="http://s160.photobucket.com/albums/t197 ... 7Front.jpg" target="_blank"><img src="http://i160.photobucket.com/albums/t197 ... 7Front.jpg" border="0" alt="Photobucket"></a>

Probably need to weather the cushions a little more but that can wait till I finish adding the necessary detail. I have no idea where to pin the Remove Before Flight tags... just threw them in for color. If anyone has any pics showing some on a seat please post em.

<a href="http://s160.photobucket.com/albums/t197 ... eBelts.jpg" target="_blank"><img src="http://i160.photobucket.com/albums/t197 ... eBelts.jpg" border="0" alt="Photobucket"></a>

Close-up of the harness system. Used old tooth paste tube foil for the straps.

I found the perfect site for you "adventurous soles" out there looking to upgrade you A to a Bombcat D model. One of the major changes was in the ejection seats from the original GRU-7(A) to the more modern SJU-17 (or NACES) seats. This sights has it all for you....

Working an a 2nd Monster Cat

Post by mcaulk » Sat May 22, 2010 2:35 pm

Working on a 2nd big cat. This one from the same squadron but done in the 3 gray TPS low viz scheme. Wanted to do a "B" to utilize the GE-F110 engine nozzles soon to be released by Skyworks!

<a href="http://s160.photobucket.com/albums/t197 ... ght4sm.jpg" target="_blank"><img src="http://i160.photobucket.com/albums/t197 ... ght4sm.jpg" border="0" alt="Photobucket"></a>

The aircraft I am modeling is an F-14B 163229 between December 2004 and January 2005. There are no markings in 1/18 scale so I make my own on an ink jet printer. Toughest part was sizing on the final print image.

<a href="http://s160.photobucket.com/albums/t197 ... Decals.jpg" target="_blank"><img src="http://i160.photobucket.com/albums/t197 ... Decals.jpg" border="0" alt="Photobucket"></a>

This is a pic of the real bird. The TPS scheme looks gray sometimes and then it looks blue depending on the light

<a href="http://s160.photobucket.com/albums/t197 ... 6346-1.jpg" target="_blank"><img src="http://i160.photobucket.com/albums/t197 ... 6346-1.jpg" border="0" alt="Photobucket"></a>

Before painting I did a lot of sanding to subdue the panel lines which on the stock kit are way to deep. This was time consuming but looks much more to scale. Drilled out the Gun Gas Vents an added a few rivets. (*note I removed the probes and TV chin pod for detailing and will add them back later)

<a href="http://s160.photobucket.com/albums/t197 ... sVents.jpg" target="_blank"><img src="http://i160.photobucket.com/albums/t197 ... sVents.jpg" border="0" alt="Photobucket"></a>

I airbrushed Model Master Enamels for the 3 grays:
Upper surface FS 35237 Meduim Gray (This looks really blue when you first put it on but looks right after weathering)
Mid Fuselage FS 3632o Dark Ghost Gray
Bottom FS 36375 Light Ghost Gray

<a href="http://s160.photobucket.com/albums/t197 ... tFront.jpg" target="_blank"><img src="http://i160.photobucket.com/albums/t197 ... tFront.jpg" border="0" alt="Photobucket"></a>

Back working on the big Cat Lets begin with the vertical and horizontal stabilizers. Not very exciting I know but a necessary evil particularly with this model as the Chinese manufacture chose to make them more like the armor on an Abrams tank than a supersonic aircraft.

So break out your Dremel a sanding block some super glue a couple of bottles of vintage Ripple and have at it.

<a href="http://s160.photobucket.com/albums/t197 ... _of_43.jpg" target="_blank"><img src="http://i160.photobucket.com/albums/t197 ... _of_43.jpg" border="0" alt="Photobucket"></a>

Next a couple of before and after shots:

<a href="http://s160.photobucket.com/albums/t197 ... iling1.jpg" target="_blank"><img src="http://i160.photobucket.com/albums/t197 ... iling1.jpg" border="0" alt="Photobucket"></a>

<a href="http://s160.photobucket.com/albums/t197 ... aling2.jpg" target="_blank"><img src="http://i160.photobucket.com/albums/t197 ... aling2.jpg" border="0" alt="Photobucket"></a>

That was the trailing edges now the leading edges... you would think these would be a bit thinner... not a chance. * In real life the edges are actually very thin and dangerously sharp. I didn't want to make the plastic to thin so they are still a tad thick.

<a href="http://s160.photobucket.com/albums/t197 ... ading1.jpg" target="_blank"><img src="http://i160.photobucket.com/albums/t197 ... ading1.jpg" border="0" alt="Photobucket"></a>

*Note - the tip of the stab is blunted from the factory requiring added plastic or in this case built up layers of super glue cured and sanded to a point.

<a href="http://s160.photobucket.com/albums/t197 ... ading2.jpg" target="_blank"><img src="http://i160.photobucket.com/albums/t197 ... ading2.jpg" border="0" alt="Photobucket"></a>

The vertical stabs are better but still require some attention. The rivets are roughly the size of scale oranges and need to be replaced with more realistic pin vise representations and the seams need to be filled and sanded.

<a href="http://s160.photobucket.com/albums/t197 ... Tails1.jpg" target="_blank"><img src="http://i160.photobucket.com/albums/t197 ... Tails1.jpg" border="0" alt="Photobucket"></a>

I am doing a later Bombcat which had stiffeners added to both sides of tails. This treatment came fairly early in the life of the Tomcat and was retro fitted to most A models.

<a href="http://s160.photobucket.com/albums/t197 ... Tails2.jpg" target="_blank"><img src="http://i160.photobucket.com/albums/t197 ... Tails2.jpg" border="0" alt="Photobucket"></a>

The detail is washed out in these pics... here is a good shot of the real thing.

<a href="http://s160.photobucket.com/albums/t197 ... =Stiff.jpg" target="_blank"><img src="http://i160.photobucket.com/albums/t197 ... /Stiff.jpg" border="0" alt="Photobucket"></a>

Did I mention that you get to make four of these? Yea! Just hit the Ripple put on some good music and gut it out.

<a href="http://s160.photobucket.com/albums/t197 ... tiffX4.jpg" target="_blank"><img src="http://i160.photobucket.com/albums/t197 ... tiffX4.jpg" border="0" alt="Photobucket"></a>

I sandwiched four layers of stock plastic together with a small dot of super glue then cut, filed and sanded the basic shape. This ensured that they would all be alike. Afterwards each layer was seperated and detail was carved and scribed into the plastic.

Used the CROSSDELTA fine 32nd offering as the pattern. Scanned then enlarged to 1/18th scale and WAMO! Stiffeners!

<a href="http://s160.photobucket.com/albums/t197 ... feners.jpg" target="_blank"><img src="http://i160.photobucket.com/albums/t197 ... feners.jpg" border="0" alt="Photobucket"></a>

Next up? Torn between assembling the SkyWorks landing gear or reworking the GE-110 engine fairings. More to follow.

Converting From A to B.

Post by mcaulk » Sun Aug 08, 2010 8:03 pm

As mentioned previously my daughter was married recently and the lead up was time consuming with multiple tasks that ate into my plans for the Tomcat. Now with the wedding behind its onward and upward.

Christa...

Image

Now back to the Tomcat.

The JSI Cat is kind of a mixed airframe with parts from the A/B and or D. The engines on the model are the early troublsome Pratt & Whitney TF30s pictured below... followed by the much improved GE F-110 turbo fans.

Image

Image

This pic is of the model with both types of nozzles in place for comparison.

Image

Converting the JSI F-14 from the "A" to the "B" really starts with these engines. Actually the nozzles are done by Jack at SkyWorks and they are great! The problem is the model fairings. The two versions are really quite different but take heart the task is relatively simple.

I began by filling the outer fairing panel lines in with Cyanoacrylate (super glue) then sanding smooth. On the "B" modle this area is smooth and very dark metallic gray.

Image

Image

Next I cut the new fairing outline from thin Evergreen stock plastic and attach over the old "A" fairings. (This gave me a base to work from) In the pic you can make out the white plastic under the filler. This looks more realistic than making that joint solid as on the real thing the engine is not connected to the fairing but slides in and out for servicing.

Image

For filler I used "QuickWood" Epoxy putty. Stuff is great! Is workable for about 15 mins... enough time to get the approximate outline. I let it dry overnight then sanded to shape. Dries hard and sands smooth as plastic.

Image

There should be a thin gap between the inside of the engine fairing and the rear fuselage. Is a pain in the &%$#% but adds to the illusion. I used a good old #11 Exacto and some thin sand paper. I started slow using the back of the blade and working from both top and bottom until I had a gap all the way through. When I over did it in a spot and the gap was too wide I put Tamyia masking tape on the engine side and ran a bead of super glue until the thickness seemed right and re-sanded.

Image

Next installment will address the landing gear problem.
