Panel Lines

[Sweb]

I'm a non-conformant where panel lines are concerned. I use them but they are placed into the finished paint lightly and just barely suggested in an effort to keep everything about the model scale in appearance. I was looking for a site that could perhaps illustrate how I fill existing panel lines in molded parts and re-render them and found this. I thought it humorous and especially poignant with regard to the trends currently employed on the subject. These days I see lightly depicted airplane shapes superimposed over a heavy base of panel lines rather than the appropriate other way around. I happen to agree with this fellows spirit and aim to create in scale what we see rather than imagine we see.

Nice words. No pics to quantitatively evaluate his judgement. I do agree that panel lines can be overdone. But sometimes this is an economy of scale. I solely do 1/72nd. What is appropriate in one scale is not necessarily appropriate in others.

Just doing panel lines for the effect is, IMO, the wrong way to tackle the problem. I try to get photographic evidence of what I'm doing and then try to replicate that. Not every panel needs to be highlighted.

I agree with you, Joe, Matt and Chris. I see what the writer is getting at, even though there are no pics to support his article. It's nothing new though; it's one of those 'fads' that seems to pop in and out of 'fashion' in modelling, more so with almost all modellers now using an airbrush. The latter is one of those tools that, although a superb and very versatile and useful piece of equipment, seems to be, nowadays, a 'must have, can't model without' item. But going back to panel lines, depending on scale, colour and size/shape of the model, panel lines are sometimes NOT required, whereas in other cases, the application of subtle lines, visible close up, just visible then disappearing with distance, can help to improve the overall look of a model. But, they aren't the be all and end all, and don't need to be included as a 'must'.

[Njaco]

I agree Terry, I see with my Dauntless that not all the panel lines were highlighted even through heavy wear. You have to work smart.

[Airframes]

Exactly Chris! Model what is seen, not what you think should be seen. The bloke who wrote the article got it right - many modellers seem to have never seen the actual aircraft they model, even in pictures! Something that makes me smile are airliner models - always clean and shiny. OK, so are the real thing - until you get up close! Seems the opposite is adhered to in the 'civil' camp - no panel lines or weathering of any type allowed.

My father was like that and it was ok. He loved the look of a plane fresh out of factory. Me - I like to see something thats been used. we both complimented each other for tips and tricks.

Matt, nice birds.

I do weathering, but I usually leave panel lines alone. My weathering usually consists of paint chipping and exhaust and gun staining.

I have looked at various models on display in various hobby shops and on-line. There have been some very nice builds that have won contests but still display overly stated lines. I'm a champion of true scale. Figuring a typical full scale panel line will accept a .025-0.030 feeler gauge at butt joints we must consider our model scales and reduce dimensions accordingly. In that regard a 1/72 model will have a joint falling at or under 0.004 inch, or about the thickness of a piece of printer paper.

One technique currently being widely employed is highlighting panel lines (from some imagined perception) giving the impression of excreted airplane bile(?) from inside out? I will agree paint weathered in those areas due to the internal structure causing a difference of heat between supported and unsupported skin (free-floating vs non free-floating skin) when in certain theatres such as the sun-beaten Pacific Theatre. The paint on the free-floating skins became much hotter and subsequently weathered worse than the skin areas attached to underlying formers, longerons and heavy stringers. But, a very subtle difference is adequate to give life to respective theatre weathering.

Then we have lap joints where the two separate skins are overlapping without a gap at all. Do we know the type of joints employed in our selected builds? This explains why we can view the F6F from the front oblique and see little fuselage detail while the rear oblique reveals the (lap) joints? It's a question I'm trying to answer for myself regarding this bird. A trip to a local museum and/or research should be conclusive. Furthermore, some aircraft had a mixed bag of assembly fasteners such as the Corsair. In certain sections it was spot-welded which means there should be no visible rivets in those areas. These areas are in the fuselage center section which comprise the wing stubs. I'm not sure how extensive the welding was but I do know it was employed to reduce the weight of fasteners. I plan on visiting Kermit Weeks Fantasy Of Flight just down the road from me to get a view of his Corsair when I do decide to build one. It is one of my favorite warbirds (I'm a round engine Pacific Theatre geek) and I'll do the due diligence to get it right.

The current kits producing molded-in panel lines and other "scale" detail are typically overstated and that's why there's always something "funny looking" about them. I'm working a Tamiya F-51 at the moment turning it into an RF-51. So far I've filled in the wing panel lines and am working to reduce the thickness of the wing-to-body fillet fairing. For example, if I measure across the fuselage side-to-side at the represented fillet area and then a similar measurement above that fillet I get a difference representing the fillet skin total thickness. That total scaled thickness is 0.200 inch. That means the skin represented on the model for the fillet fairing is 0.100 inch. It was actually in the region of 0.040 inch. The panel lines are overstated and I'm filling them in. Once the model is completely painted and decals on I will return to it with masks and lightly indicate where the panel lines are. This will not cut into the plastic. It will cut into the paint only. A very light dusting of darkened chalk with a sable brush will be all that is needed to give them adequate life. In other words, 5 feet away they disappear.

Again, I'm just a scale appearance geek. I have additional rants but it's Sunday and I will give it a rest. Thanks for the opportunity to share my psychosis. One last word - I coming back into scale plastic modeling from along hiatus while working on scale 1/4 flying warbirds. There are many techniques that are new to my bag of tricks I must review. My plastic modeling days were scrappy times of imagination-over-money where I had to make the most of the materials available to me. Filler putty wasn't one of them. I always filled using the plastic from the model parts trees by working it into sprues, flats and shapes. The advantage was no need to primer the surfaces: no gaps or mods that weren't solid plastic and a final sanding and polishing to restore the model to the as-produced surface gloss precluded the need for primer. This takes me to painting which I will discuss at another time. Thanks again.

Edit: Matt308, looking good. I do see the Corsair lines and the skipping in them. When these birds are painted they are painted with an epoxy primer and top-coated with a polyurethane impact resistant finish. It's a heavy finish. I use it in my daily activity as an aircraft mechanic. This paint flows into the panel lines and seals them completely. As it is an exceedingly flexible and durable finish virtually impervious to any chemical attack, slipstream errosion and airframe flexing it looks good for a very long time. It will begin to "chalk" after much exposure time on the upper surfaces (sun baking) but rarely does the finish free itself from joints. The joints do, however, collect dirt if the airplane isn't maintained properly but it is a slightly darker appearance and uniform without skipping. The armed services used to use regular enamel paints that did not conform to the high weathering/wear resistance of the poly finishes. I was a KC-135A crew chief and the USAF used to finish those birds with a silver Corra-Guard silver paint that was like a white-wash when dry. It would rub off like a silver chalk. Nasty finish and it looked like crap in a very few months from hydraulic fluids, fuels, and constant wipe-downs. And, the frickin decals (yes, they were all decals) didn't take very well. Then USAF went to the silver poly finish seen on those birds now. It lasts forever without weathering.

Panel lines is a difficult area. As well described above by Sweb, the actual thickness of a panel line if scaled down 48 or 72 times is miniscule, and apart from a moveable surface or removeable access panels, there would be little visible above a thin slice on the panelled surface of the model.

But, I always run a thin wash of black into my panel lines as I feel that a model looks somehow incomplete without them visible and and highglighted. Why is this? perhaps it's the perception that you know they are there if you were looking at the real thing and so the surface just looks too plain without them even though it is perhaps more correct to the true scale. The only way I can see around this is to highlight them by running a wash in but to keep it as light as possible to keep the visisble lines looking as thin as possible, this is perhaps a compromise between scale accuracy and perception, but works reasonably well for me, I guess it's a matter of personal taste.

Props to u for ur attention to small scale details Sweb.... I tend to overdo my panel lines slightly, atleast on my last 3 kits, partly due to the fact that I want them to look weather worn and abused like they did in the field....

However, in 1/32nd scale, as u have noted, these lines would be almost unnoticeable from 5 feet away.... So I give em alittle extra to stand out....

Heres a couple shots of my last 2 kits, both of which won Members Choice Awards here...

Les, I gotta admit, they look great. While one can "get away" with almost anything on the German machines because of their very busy schemes and theater climate weathering, builders of other single-color machines require close attention to "scaling" their modeling skills to respective theaters. For that, you're Corsair is a beaut. Very, very nice.

Edit: I was around those Pacific islands for a while doing some work and had to do some hopping from island to atoll and such. One of the things I remember is the iron in the soil, which was like a clay, and when it rained during the monsoon season it got all gooey and slimy and stuck to everything. There were many times I had to load kids in the back of my little Datsun pickup (take them to school) as weight to make it up even the slightest grades without sliding backwards. You didn't want to get a running start because you'd end up out of control on the down-hill run (slide). When that stuff was wet it looked like a very dark orange brown and dried to a light dusty-looking orange.

Heck, that's brough back memories of trying to get a vehicle through a particular African jungle. I can still see - and smell, that red-orange mud!!

[Maglar]

I agree with him, and this picture only backs it up.. over done, over cooked, burnt, not even tasty!

A nice little panel wash outside of black will do the subtle wonders..
