Great looking decal work Joel, it's all coming together now...

The extra prep before laying them down is something i'm taking more and more time time with on each model as it's plain to see that a glossy, mirror-flat surface accepts decals best. Any silvering i've had in the past has surely been due to a microscopically grainy matte surface.
I share your pain with stencils as i've just completed several long sessions with them on my "terrible teens" F15e. I think there were as many decals on the ordnance alone as on my last WW2 subject !

Paul,
Thanks so much for stopping by and the thumbs up, it's much appreciated.

Believe me, I sense literally your pain in stenciling a modern jet with a full weapons load. I did a F-4Band a F-15C with full loads one right after another, and the decaling with stenciling was pure burnout. Looking forward to seeing your finished build here.

Joel, your Hellcat is coming together really well. With the decals on it's close to finishing line and the hangar doors can slowly be opened now. It's always a great feeling, isn't it? I also have put on the last decals on my Aussie Ventura tonight.

But as far as I remember, your decals show the engine of Kenneth Hildebrandt and not the one of Alex Vraciu as you have planned ealier. Am I right?

Torsten,
Thanks so much for stopping by and checking out my Grumman Cat. While I've made a lot of progress, I still have that much more to go. Just started the engine, haven't touched the gear one bit yet either.

As for the markings, I had to make a emergency switch as I screwed up a decal from sheer carelessness, so better change plans then try to find a replacement decal of the exact dimensions.

Terri,
the decal was surely a let down, but it did teach me a valuable lesson. Take nothing for granted and check everything before I start or at least prior to a new stage of construction.

Hi Joel

That's good advice. And I'd extend it beyond weird decal design incidents like this to all aspects of modelling - i.e. don't even take it for granted that something that you've done countless times will work without fail - there's always scope for a build to do the unexpected and turn 'round and bite.

All the best

Joel your Hellcat is looking excellent so far. The WWII tricolor scheme has to be the coolest aircraft camo scheme the US Navy ever concocted.

Mike,
Thanks so much for stopping by, checking out my Cat, and taking the time to post your thoughts, they're always most welcome.

Not so sure about the tri-color scheme being the coolest all time USN scheme. While I've never gotten around to building any Naval aircraft from the golden age of aviation, those pre-war schemes are certainly quite colorful and super glossy.

Been slowly working on the Hellcat's Pratt & Whitney R-2800-10W Double Wasp engine.

I made the decision NOT to use the PE ignition wires as they just don't look right being flat, so the 1st step in the wiring process was to remove the square shaped ignition manifold that is molded onto the crankcase cover. Here's the casing without the manifold



The crankcase cover was painted with a custom mix of Tamiya 10 drops of XF-53 Neutral Gray to 1 drop of XF-17 Sea Blue then thinned 2:3 with Tamiya Yellow Cap Lacquer Thinner.

Next was to fashion a round manifold which I made out of 1.0mm round lead wire. I haven't sanded nor polished the manifold as yet in these pictures as it's really quite rough in texture.



then I dry fitted the ignition ring, made final adjustments to it, and then dry fitted the crankcase cover to see how it all looked as one unit.



I decided to add the cylinder gas equalizers both between the cylinders, as well as smaller pipes between each rocker Arm cover. These were all made from .7mm and .3mm lead wire.
Then I primed both banks of cylinders with Mig Ammo Black Primer



After the primer had dried for a day, I air brushed on Alcad2 a/c101 Aluminum. Since the cylinders are caste, I didn't want a smooth nor shiny texture, so the flat primer was a perfect base. I let the Alcad2 dry for a few hours, then applied Tamiya Black panel line wash, and painted the push rod sleeves with Tamiya X-1 Gloss Black.



The next step is to start wiring up the big Wasp.

Hi Joel

That's a great use for lead wire. I always keep a supply, but I've not seen it used for an item like that before. Very effective indeed. I'll remember your trick.

All the best

Magnus,
Thanks so much for stopping by, it's always appreciated. Funny, but working with lead wire is so much easier then copper or stretched sprue.

I'm halfway through wiring the big Wasp, and so far so good. Pics as soon as it's fully wired and then their painted.

Terri,
Thanks so much for stopping by and checking out my Grumman Cat. Today I finished the front bank of cylinders with their ignition wires and started on the rear bank. I noticed that one of the gas equalizer tubes between one cylinder was crooked, so I removed it, and replaced it in the correct orientation. looks a lot better now. Will be doing a small update when the wiring is done and painted.

Work continued on the P&W R2800-10 Wasp engine with the addition of the duel spark plug wires for each of the cylinders on both banks. Took a good 10 days to complete the process. I used .4mm round lead wire as I found it much easier to work with then Copper wire, but you need to reshape each wire after gluing it in place as it's really easy to kink them.



Then is glued it to the engine mount in the F6F-3.



Next came the dry fitting of the engine cowl



And finally I stepped back and took a look. Damn, it finally is starting to look like a -3 Hellcat.



Now I can hear all the murmuring about the weird color wires, and what gives with that. I use to paint the USN WWII ignition wires a Brownish/Red, almost a hull red, but once I started to take a look at several restorations and a few pre-restored engines, it became apparent that I had the color all wrong. Here's an unrestored engine



and here are a few restored engines.





and one close up



It looks to me that all are a metal jacket type wire that seems to be a dirty Yellowish coating. So I decided to go with a yellow/brown, and that's the color that you see. What I haven't done as yet is apply a dark brown/black wash to dirty them up some. That comes next with some dry brushing of the crankcase.

So what do you all think? Am I on the right track or totally off base? What if I mixed the original color with some aluminum to make it less intense?

I was also a little disappointed that none of the gas equalizers that I made can be seen unless you really get up close and personal with the front of the cowl. Totally my fault as I should have checked it 1st.

Joel - Judging from your photos of the restored P&W's if I had to guess I would say the braided sheathing and fittings on the ignition leads looks to be gold anodized aluminum. It looks almost like brass but I doubt brass would be used in the presence of all that cast aluminum due to the dissimilar metals/ galvanic corrosion thing . If this is accurate hardware stores have carpet edge strips of anodized aluminum for an up close color sample - you may even have some in your home-
Either way I think your engine looks superb. Once you tone the yellow down as planned I'm sure it will look fine.

Richard,
Thanks for your input, it's most welcome.

After looking at the bright yellowish wiring for a few days, I concur with assessment, and will be using a Tamiya black wash on the wires, plus dry brushing the crankcase and adding a wash to it as well. A few pics to follow in a day or so.

Hi Joel

Excellent progress on your Hellcat.

You've raised a very interesting question over the colour of the ignition harness. Some of the shots I've found online as a result of seeing your post have even shown both the brighter "brass" and the dull "copper/bronze" (I'm talking colours, not metals - thanks for the insight into corrosion problems Richard) mixed on the same engine. But none of the photos have shown the rich "copper/brown" I've often unwittingly used on models.

So, I'll err towards a dull reddish bronze in future, not overly saturated in hue. It might be a bit boring to some viewers, but is likely to be more accurate, especially if one takes "scale effect" into account.

You're well on the home straight now - I'm looking forward to seeing your Hellcat finished.

All the best

Rowan,
Thanks for your insight into the wire color issue. Like you, I never thought that I was so far off in the wrong direction. Just another example of how the Net has changed modeling and how we model.

this week is really a busy one between work and home, so almost no modeling as yet, but I did get to apply that dirty wash, and I think it's about as right as I can get it without repainting, and I really don't want to go that route.

Before:

Hi Joel, nice work on the decals. I can only imagine your irritation at finding the mistake; I have never seen that before. And as you said, it is always a good idea to look over the kit contents before construction, very good advice.

You engine looks like the bees knees, very nice indeed!

Ernest,
Thanks so much my friend for stopping by and posting, it's really appreciated.

It's kind of funny that the ABC's are still so important like checking the kit contents before construction, and working out your build plan to avoid issues when you're well into the build, and changing direction is so easy.
