Shelby Cobra Coupe by DocRob - Model Factory Hiro - 1/12 - multi-media - Le Mans

[DocRob]

I´m not very experienced, when it comes to finishing car bodies and for a while, I debated with myself about leaving the clearcoat as it is. It looked very good and had a high sheen, but it was not perfect.
Out with the sandpaper and polishing compounds. I started to wet sand the whole body with 4000 grit sandpaper, which made the surface nice and even, but also dull.



Of course, I tested my approach first on a lower body part, than on the roof, using 6000 grit sandpaper next, followed by 8000 grit. Then I rubbed in the Tamiya polishing compounds from coarse to finish and added some Tamiya polishing wax last.
Yep, looks good, not the slightest orange peel effect left and a high shine polish. When ready, I will take some outside pics in the sunlight, which show the effect better.



Cheers Rob

Wow, looks great!  Did you do all the sanding and polishing by hand?

Thank you Gary and yes, I do all the sanding by hand. The first round with 4000 grit was the longest naturally, taking about two hours, permanently checking, if there are still imperfections visible. It´s a thin line, getting an even surface and not sanding through on some corners, a task, I wouldn´t like to rely on with a machine.
Polishing might be possible with my Proxxon micro drill, but the cotton bit easily catches on corners and there is a risk, dropping the body. Luckily the Cobra is a thoroughly curved lady, which makes sanding and polishing easier than with an 80`s brick style car.

I am really happy now. Since about two month, I´ve been working on the Cobra´s body and now, the shell is ready so far. I put in a lot of elbow grease to achieve the finish, but like I said, it paid off and now, I have a squeaking mirror shine finish, only faltering the bright sunlight outside, to let it really shine.
After the first and most intense 4000 grit wet sanding round, I let follow the 6000 grit and the 8000 grit wet sanding job, followed by the three Tamiya polishing compounds coarse, fine and finish. For now, I left out the final waxing, because I have to permanently handle the body and will apply it last.
And now out onto the terrace, shaking some cocktails for my wife and me, to loosen the arms 
Cheers (litertrally) Rob

Rob, are you available to polish my real size car? 🙂 I do have an orbital buffer to help your sore arms....

Your results are just amazing on that model. It looks better than the real car.

Hehe, I just prepared to Widows Kisses, perfect cold weather cocktails tasting like licking on an old silk curtain, which basically means, I´m out of order concerning transatlantic car polishing jobs. I´m sorry, but I would spin around your orbital buffer and not the other way around, Yves .

Thank you Ken, today I applied Tamiya´s polishing wax as a last coat and the shine became even brighter, right along my smile. But now, I turn to doors and windows, another daunting act.

Cheers Rob

You know, I've been debating whether I should mention this or not...

 

The idea is to scale down the car, NOT scale up the lumber it's sitting on...

 

Where on god's green earth you obtained in scale metal flake blue paint? They don't make such an animal... So you see my point....

 

So please stop scaling up the wood... {chuckle} It confuses us....

PS: very nicely done Brother... VERY VERY NICELY DONE...

You got me there Egilman, I made it all up with some AI and Photoshop. This Cobra is fake .
Earnestly, the grain of the flakes in the metallic color gave me creeps beforehand, as most metallic colors look way out of scale on car kits. The fear was unfound, the Number Five color is exceptional.
Ok, I will build up some ladders now, to climb onto my overscale terrace table and enjoy the unobstructed view 

Cheers Rob

This build is like a rollercoaster ride sometimes. After checking my building sequence again (very important), I decided, it´s time to add the doors, which means, I have to deal with the side windows, a task, I really feared and I was right to do so.

This is, how it should be done. After drilling all the holes for the rivets with a 0,7 mm drill bit, you cut all the window panes and fairings for the sliding window from a luckily pre printed clear acetate sheet. This proved to be not so easy, it was hard, to have all the strips look equal. I tried first to use my DSPIAE profile cutter, where the blade bet slightly with the long cuts and rendered the parts unusable. I moved on to use a steel ruler and a new scalpel blade then.
But how to glue everything together and align the parts perfectly, for fitting in the rivets.



I decided to improvise a bit. I skipped the spacers (CS5) and used 1mm wide double sided clear adhesive tape instead. To reach the sufficient thickness, I had to apply two strips onto each other. These strips with the CS4 parts were then glued onto the window pane, trying to fit the pre drilled holes. With the second strip in place, I re-drilled the holes again, now with a 0,6 mm drill bit through the adhesive tape and then inserted the rivets. Luckily the residues of adhesive tape in the holes fixed the rivets.
Unfortunately, cutting and assembling must be made on a relatively hard surface and that lead to scratches. The result looks horrible, but I think, I have to live with that, re doing the strips would result in more scratches on the window panes and I don´t have spare acetate.
The only upside, the windows actually slide .

Thank you Craig and Alan. The only thig which got pushed, is myself out of my comfort zone and not the first time through the build .
I really would have liked a simpler solution for the windows. Drilling the acetate produces burr, which needs to be removed. Don´t use PCB drill bits for this task, there will be even more burr. The classic HSS drill works best. Unfortunately, the windows have some scratches and the acetate strips are not very even, but I have to live with that.
Sometime I wonder, why I was so scared, to pull through with the rigging job on my Duchess of Kingston build .

Cheers Rob

You know, they lived with it on the real car... The door windows were plexi on the real car and the parts for the slider were as well just glued together... The rivets were for reinforcement...

 

A few minor scratches adds to the authenticity...

 

This is my opinion of course, but they are there on the real thing... Absolute fact... So, nothing to be sad about, an inadvertent detail added by accident, but very very realistic... (especially since you have to be on top of it to see them)

 

Perfection I say...

Thank you Egilman. You are right, I think. These Cobra Coupe´s were build up in haste and I guess, the whole bodywork wasn´t fitting perfectly and the finish was far from perfect. The windows were no exception for sure, and the real plexi is as vulnerable as my scaled down acetate parts and also scratch prone.
But like so many times, I´m guilty of not being a rivet counter . I like to build my own reality with kits and with the Cobra, I´m looking for a fabric new finish. The side windows hopefully lay in a bit of shadow in the end .

Cheers Rob

[DocRob]

The picture may looks like pure happiness, but it isn´t. I feel overwhelmed by the Cobra right now. Test fitting results in damages and abrasion and when I glue the parts in place, they don´t fit like planned. To add to the miserable situation, I have lots of paint lifts and fogging on the paint from CA glue. I have two spots on the body, where I fingerprinted CA glue onto the body paint and lifted or distorted the finish. I´m more than a bit frustrated. This is the sequence of building where everything is supposed to fit but doesn´t. I have to grind resin away, to get a halfway decent fit for the doors. Most of the problems occur during fitting the inner body fairings. Nonetheless, the rear hatch and the doors with windows got installed. I´m now down to maybe 80% of my achieved look and my border of tolerance is nearing quickly. I hate to make corrections for flaws, but with the Cobra, it is necessary. Don´t get me wrong, the design of the kit is fantastic, I´m just not up to it.

I'm the worst to tell you anything about patience and perseverance, but making a model, in my experience, is a succession of frustrations and challenges you will have to overcome. Some challenges seem bigger than others and viewing your capabilities I am sure you will overcome this one as well!

Hang in there!

Walter.

[Kevin-the-lubber]

I’m late to the party but have to say what an incredible model and build. You are being way too hard on yourself Rob (says one perfectionist to another) and you are clearly more than up to this challenge!

Thank you Walter, for now, I will hang in. My level of patience is generally very low, luckily my perseverance isn´t. Usually, I have to disagree with you about the succession of frustrations in modelling. To me, its mostly challenges, what defines a build and I like to challenge myself due to my projects and learn something new every day.
The Cobra is a beast to build somehow. The main frustrating aspect is, preparing and finishing various sub assemblies over a long time and during the final assembly destroy them partly due to abrasion, CA spills, paint lifts, etc. The fact, the Cobra is made up like a real car doesn´t make things easier. The build is complex and tolerances are tight and even the slightest deviation sums up to disaster in the end.

Thank you for your supportive words, Kevin. I think, I will skip macro photos for this build from now on . Most from the frustration arises from the level of destruction, I conduct during this important phase of the build. It was challenging but rewarding to build up all the sub assemblies, but now it seems like I´m tumbling downhill with the build, adding scratches, paint lifts, CA fogging and not perfect fitting doors, etc. 
When starting a build, I have a picture of the finished model rendered in my head, with every detail sharp and clear. Reaching this image in the end is my main motivation in modeling and leads me through all oncoming challenges. Where I´m not good at, is a change of plans. If I´m not able to fulfill my projected result, I easily get annoyed and may bin the project, which luckily doesn´t happen often to me. Quality wise, I´m closing in onto the black hole with the Cobra, but I hope, I can somehow have a partly satisfying outcome.

Cheers Rob

[DocRob]

To do something productive and without destruction, I added details to the rear area. The rear lights were painted with Tamiya clear red, have a turned aluminum base and a small rubber ring around.



Next was the feared addition of the firewall, which fitted after a lot of sanding and grinding and is held in place wit a screw. Of course, there are a lot of scratches to be repaired. I also knocked off some parts during the process, which will be added later.



Then, I added the dashboard, which luckily was an easy task. Concerning CA fumes, if you are spotting into the foot wells, you notice chalky white residue. I never experience this kind of CA-fogging before and I always use the same glue and used the semi matte black often. Strangely the fogging reaches very far from the gluing area.

Yup, macro is an evil something, isn't it. The worst of it is that getting back into model-making led me to buy a new camera and 2 macro lenses, which shows up every last, tiny blemish. Vaseline all over the lens is the way to go 😄. I can't wait to see the engine in the bay, this one super-realistic model kit! 

[king derelict]

This has seemed a massively complex model from the start and it’s been inspiring watching you knock down the challenges one by one. I know that feeling when dry fitting damages stuff you already did. I usually find having successfully dry fitted a part as soon as I apply glue somehow everything changes and it won’t fit.

I think MFH will go on the list of kits to admire watching others build but stay well clear of myself. I class you as one of the heroes of this site. I’m the kid in the corner eating the glue.

Good old Vaseline filtering, but I´m not David Hamilton . I like my macro lens for model pictures not only because of it´s capabilities of showing my failures in large, but also for it´s angle of view (90mm lens), which grants a distortion free image.
In case of the Cobra, I use my Iphone mainly, where the body is involved, because my camera is not capable to render the blue metallic correct, equal which white balance or color parameterizing I use, it is wide off the mark.
I hope the chassis will be married with the body soon, without loosing half of the kit parts during the process. Only thinking about the many intersecting parts makes me shiver.

Thank you Alan, I´m blushing with your praise, but you shouldn´t sell yourself short. When I see your figure painting skills, I can only marvel. You built that weird Yak kit into a beauty, if I remember it correct.
MFH kits are special. Demanding due to the use of different materials and very complex, because of the level of detail and being closer to the real thing construction wise than others. But that doesn´t mean, they are not buildable by an experienced modeler. What you need is a very thorough and methodical approach and a lot of perseverance. The Cobra was possibly not the best choice for a first MFH car kit, but it is still mainly fun, except for the last days. So often, when I work on this kit, I have a smile on my face, when I see the ingenious design of parts or intelligent choice of materials, more than with most other kits.

Cheers Rob

Poco a poco, I grind my way through the Cobra build. Today, I assembled the tank filler cap, a seemingly small task, but it involved about twenty parts and is functionally. I polished the cap itself with Autosol metal polish and added the numerous etched parts and rivets.



Then I started with the steering wheel, which got primed, airbrushed in a mix of red brown color and sand. After drying, I applied several layers of dark brown and red brown oil colors, thinned with fast drying thinner for a realistic looking wood texture. Tomorrow, I will apply a clear coat as finish.



Finally, I repaired the damages to the firewall and pinned the lower side to the door fairings with brass rods for enforcement, to close the gaps in this area.



Cheers Rob

[DocRob]

The tank filler cap is really working, just open the tiny latch on the left and put in the juice - errr - not so fast, the tank isn´t installed right now .



After priming some interior parts for later stages, I had an idea about how to deal with the wheels. They are made from cast white metal and were cleaned in the tumbler polisher at the beginning of the build. 
I thought, I have to give them a bit more shine, to keep the eyes trained on the wheels, letting some other mistakes skip more easily . Hand polishing proved difficult and I found, a conical head M4 screw holds the rims in place in my accumulator drilling machine´s chuck. Then I sanded the wheels with fine grit sanding sponges, followed by polishing with Autosol polishing paste on a cotton rag.



Now, I like the result. Later the wheels will be airbrushed in black and then I polish off the higher parts again, which are now shiny. Of course, before airbrushing the rims will be cleaned properly. the polished left one on the pic has a lot of dirt accumulated.



Cheers Rob
