Seeing as that Napier engine is sitting in a Humbrol paint pot, either you have great eyes or great glasses!

Nice wire work.......

i scratched some in line cylinder engine and the twin gannet gas turbine ,actually working on the db-605 engine on a Veltro kit but never really try a jet engine. The pieces are sure litter than a 1/32 but with a major scale you need more details and more precision, in 1/72 you can allow some missing part Cool.

heres the typhoon napier sabre 24 cyl before paint

and the gannet twin engine before the dirt wash

On the j-79 i will try only to detail the back chamber section and the exhaust terminals that are totally smooth inside Sad

Thanks bsyamato,

If you can actually detail J-79's in 1/72, you are a better man than me!....Smile

Huge and good work Bockscar! i like scratched engines Toast

I have the revell 72 phantom, high detailed kit but the afterburner chamber is one of weak point of the kit, will follow for some future tip

The actuators help give the inside of the turkey feathers a nice look:

It was a nice sunny Sunday and 70 outside, so I sat under our patio umbrella with a wobbly pop, and cut lumber:

Two for One!:

I made a couple extra in case I wobbled when I was supposed to slice:

I will now try and glue 20 of those per exhaust into place.

I merely cut the spool stabilizer locking tabs off the spool axles;

they would make great Thud feathers...lol...

There they are, the 'blast rings', to hide my aft turbine blade indiscretions!Embarrassed

Already, the blades look better.

No, you did not see imperfections in blade spacing!!!...lol....

Shissh.........

Hey, who put specks down there?!!!!

Phew!!!!

Looking a whole lot better now.

the paint hates me, and I hate it. I'll let you know how the colors go.....

So, back to blast rings;

I'll cover up the nasty blade tips with the blast rings, and still have more blade showing than the Tamiya version.

I simply cut the tape spool axles out of Scotch tape dispensers, as they were the only junk styrene on hand that came close to the build's tolerances:

Yeah, they will cover up the builder's mistakes pretty good;

That is a pure styrene so as many of you know, it is crispier than kettle-cooked chips;

I'll cut the axles down to match the rest of the components, and when the critics look up the burner cans hopefully they won't get.....you know what in the eye....lol....

I get about an hour every Friday night, so please don't get too ornery if this ain't happnin' fast enough....Wink

If I get a chance to detail those blast rings i will post.

I checked the burnt iron and olive drab paint and it has gone into seizure waitin' for me......

little darlins, whithered by idle time....lol......use it or lose it......

So, I doubled up the blades:

These are the aft turbine-flame components:

Ugly, yes, notice I sculpted the holder ring a bit:

That's the set, pre-assembly:

Should be far enough away from the eye to cover up some of the rough spots....:

Shissh...hope I can do more tomorrow........

Those exhaust turbines confirm I am no longer in a race.......

Those are straight exhaust or aft turbine blades:

So now I need to double them up,, for a total of 32.....close to J-79 spec, but not the true final count.

I'm not GE or P&W, so I was still with Revell tolerance for this kit.

So I've managed to get past the hard part, and

put together those flame holders:

Looks like a cast iron burner for deep frying turkeys:

Double turkey dump:

Crude, but effective:

Lookin' down the can:

Should look okay once done in burnt steel:

So that's a big step completed, now I can start gluing the bird together.

Here's the exhaust cone, glued to that disc I cut, and the pen tips have been filled with sprue and rounded off:

I will glue the legs of the holder into those two fairings I cut. I have begun to glue all of that lumber in these pictures onto the discs. I had a few problems, maybe due to working late at night. I cut a few of the turbine blades a few thou too short.....

There's the other cone:

I thought I'ld get it all finished this weekend, but the snags added up like tolerance stack.

I'll try and hide the short blades behind the legs of the flame holders......Whistling

....good news, my turbine blades are longer than Tamiya's, mind you, their exhaust cones are about a 16th wider, so it will all even out, phew!

Another day, another evolution.

Cut the rondels out of sheet styrene.......they are going to hold the turbine cones and blades.....

Really, really hi-tech, super hi-tech----Scotch tape dispenser rolls....pretty close to 1/32 F-4 burner can inner dimensions.

So I cut the inner ring out, and cut it evenly through its radial axis, sanded the faqirs, and cut them to reduce

their own radius to match the inner dimensions of the head of the burner cans.

So many empty Scotch Tape Dispensers....so little time.......

So there they are.....recommissioned to act forever as aft-turbine blade holders......

Ouch, and the pen tips......gotta stuff the tips......Ouch.......ever been to hospital.......

Yickitty, can hardly see it......

Doo Daaaahhhhh

And then I had to put that all in motion.......nice.........not bad for a pen point, but only six reinforcements....Bastiges!

Yah, wish I coulda' done hat with the Easy-Vac-Oven..........lol.......

Itchn' for Scratch II: F-4 J-79 1/32 Flame Holders
Posted by Bockscar on Saturday, January 28, 2012 10:50 PM

Berny [Phantom Phixer: see First Annual Berny Memorial Group Build] played a great joke on me and challenged me to build scratch J-79s.

Starting with turkey feathers and moving forward, I managed to get much of the visible engine scratched out.

Emulating Berny's method, along the way I bought kits and AM parts just to check my accuracy. Mind you, this is in no way an attempt to make a super accurate or perfect scratch representation of the J-79, but it might help those who want to try scratch building to have some fun and achieve some nice results.

My build was originally for the The Official F-4 Phantom II Group Build 2011, and thats where I met Berny.

I started with a heavily warped old Revell 1/32 kit, #4754 RF-4E F-4F, but I left it as the original F-4G and began the long task of making it look decent.

So, much putty later, we joked it is now officially and F-4P because of the Rhino-Plasty, I am getting around to the flame holders for the J-79s. Here's the challenge, to make something that looks like this:

and

Piece a' cake, right?

So, here's the selected stock and rings I cut:

Here's Berny; "Dom, you gotta lot a' work to do son......"

"I told you the inside of those cans were green, Dom....."

I love those Flat Bastige files.....

The great pretender.....I found the end cap from a Galiano bottle.....

Nice hu?....prawlem is that it only has 6 spkes, F-4 J-79 needs seven......BASTIGES!

Dream on, pal.......

Had to give the Revell kit 'hips'.......

reinforced the hips....

That's the split n' wedge.....

Oh Yah, the the turbine caps.....lol......stolen from old pen barrels......hmmmmm......like the rings above....

So, now I need to put together the spokes, make those caps look like they are turbine capable,

Then I can glue the basssige into place. - green inside the cans........lol.....
