NSR and their Corvette C6r hardly need an introduction, together with the 997 they've formed the backbone for many GT club racing series all over the world.
Renowned as they may be for being "performance cars", one rarely sees an NSR on the track that's being subject to some detailing TLC.
Maybe its because NSR's policy to produce uni colored "test" versions and white kits before releasing "liveried cars. By the time the "stunners" become available every body already bought and prepared their "runner".

Which is a shame as, I have recently found out, the C6R is actually a very true to scale slotcar, that with a bit of TLC, can be turned into a just as stunning as fast runnig scale(d) replica.
With the recent releases of the Vantage and the Z4 getting most of the slotracers attention...
..and me having an old white kit laying around......time to return this golden oldy back into the Limelight.

The basics of "How to Relivery a Slot car" have already been covered extensively by Richard's excellent tutorial in the scratch build forum.
Here I'll try to highlight only the parts where I've used a different technique and or different materials.

Reference pictures: Get to know your subject

First step for every project is ...to pick a subject. In this case I chose the #50 car as raced by the french Larbre team in 2013, and as I'm a Le Mans fan the version as it raced during the famous "24 heures".
The second step is to gather reference pictures from every possible angle. I've posted just two of them here, but usually the folder I create for a project will contain dozens of images.
If like for this project I also need to draw all the logo's for the decals set it can be more than hundred images.
With the growing bandwidth of the www this job has become so much easier, with time you learn variate your search descriptions and even search languages to get that image of that elusive angle, detail or logo.
Sources can be anything from the obvious automotive sites to annual PDF reports by a sponsor's company.
Sometimes you find high resolution images of your subject on Flicker, sometimes these images are blocked from downloading, with a small app like screen capture the resolution will be good enough for you to use as a reference.
Anyhow...even if you use a commercial decal set with a proper decal plan, reference pictures will help you to get to know your subject.
And that's important because you need that to determine what it is that "sets off" your car, what makes your car tick.
The best approach to get a good result is not to try to make a 100% scale replica, but to focus on creating a scaled down "impression" of your subject.



Creating templates, trying to flatten a banana
To make the decal sheet for this C6R the logo's and straight lined striping needed to folow the curvatures of the body panels.
In other words, I needed to draw straight lines for on a curved surface.
Doing a couple of templates of those body panels is a very helpfull step in converting a 3d object into 2d surfaces.
Actually this applies for all cars, even those with more angular edges like the GR5 M1.
There's always that slight compound curve that's hardly noticable, but enough to make them not fit or worse brake up as you place them on the car.
Savage experienced this with the Apple decals he made for one of his 935

To create these templates I use Tesa "pink" precision masking tape. Its 50mm wide which is enough to cover most 1/32nd bodypanels.
Its also thin, strong and has a bit of flex, most important it has a nice clean edge when you cut it.
Still a sharp knife is a neccesity, can be a triangular X acto hobby knive, but I prefer to use a #11 scalpel.
Chance blades frequently, you'll be amazed how fast a blade blunts by just cutting "paper" tape.
Apply the tape in sections, I usually treat the body panels one by one and cut them along the recessed panel lines.
The good news is you only need to do half of the car, but make sure that you mark the correct centerline first.
As you can see I drew a kind of mesh over the taped up body, this "mesh" helps to line up the different body templates after you've peeled them of the car.



Drawing the Templates and Logo's for decals: Vectors or pixels, working with layers
Next step is to stick all the templates that you've cut on a piece of paper and scan them @ 300dpi or more.
To work on this scan you need a software program that allows you to at least reposition and resize images.
Best is to use software that allows you to create separate layers. (as you will be placing images on top of images)
Due to my line of work I work on a Mac with professional Adobe software like Photoshop and Illustrator, but there are free software packages for windows like Paint.NET (pixels) and Inkscape(vectors)
They may not have all the gismo's and filters of the proffesional suites, but with a bit of imagination and some trail and error you'll be able to get good results. Even with a simple program like Word.

So now you've got your scanned templates. If you're doing a simple decalsheet, you can use pixel based programs and work directly in the scanned document.
Simply lock the background layer and create a new layer to paste and resize your logo's in.
If your decalsheet is more complicated it is best to use a vector based program and convert your template scan to a vector illustration.

The 3 images I've posted above show the main steps from scanned template to full decal drawings.
For the main templates you only need to draw half of the car and then copy it and flip it to get the mirrored image for the other half.
That centerline I mentioned before, well here's where that pay's off, or where you pay the penalty for any inaccuracies.
But nothing that can't be corrected. This template and decal drawing bussiness, its a lot of trail and error.

The good news is...you wont have to do all this template work..at least not for the NSR Corvette C6R, as I've already done that for you and have attached them as a PDF file to this post.

Advanced Graphics: Adobe Illustrator and Correl draw, using Arc, Warp and Auto trace filters
For those of you that work with vector programs, check your filters/plug-in tab for Arc, Warp and Autotrace tools.
Auto trace is a plug in that does exactly what the name suggests, it will trace the outlines of an image for you and convert it into vectors.
I used it to trace the running horse in the demeco logo. The Arc and warp filters a great tools if you need to make an image or logo fit a specific body curvature.
Like for instance the Motul and Club de Cologne logo's on the roof or the Michelin logo I used for the tyre decals.
The good thing about these fiulters is that they do not modify the vector drawing itself, they just alter the display and print function of the items you've applied the filter to.
The downside of these filters is that their application is linked to the horizontal and vertical orientation of the item its been applied to.
So if you copy the logo with an applied filter to an other document (like the one where you collect all the logo's to print your decals) keep them oriented in the same horizontal en vertical way.


Testing testing testing
During the drawing process I usually make a couple of test prints to check the fit and sizes and placement of the logo's on the actual car
The templates are a good guideline, but you'll always find these small discrepancies when you compare them to the reference pictures.
For the C6R I went trough about 3 or 4 of test draw, print, redraw cycles, pictured below is during stage 3.
The panel fittings are good, but the black warping around the rear fender/ bumper area did not align correctly.
Its in these stages that you try to figure out which parts of the logo's and striping can be combined as one decal and which parts need to be seperate items.

The stuff I use to do my test prints are A4 sized paper stickers from Avery Labels
It says on the site that they're for Inkjet printers but you can use them for Laserprinters as well. I usually print several sets on one A4 sheet
The glue they use is just strong enough to wrap the prints around curved body panels and you can even reposition them a few times.
But as theyre more difficult to reposition than the decals, some times a few times is not enough. So you start over and cut a new sticker form the sheet.
The trick in cutting is to apply just enough pressure to cut trough the sticker but not the backing paper.
With the tip of the blade you can then peel them off and (re)apply them on the car.
To position the paper stickers I usually start in one corner where I'm sure it has to align with, and then gently let the sticker drop on the car by its own weight.
If its position is good I'll rub the sticker down more firmly, starting from the middle working towards the edges.
If you get a few wrinkles while wrapping the sticker around curves or edged that's ok because the paper is much stiffer than the actual decal film you'll be printing on.
But if you need to apply too much force to stretch the paper around curves or edges you may considering splitting the decal up in more pieces.
Decalfilm is much weaker than paper.
And normally you don't have to go as far as I did here with a full body wrap. you just print and cut the parts that will be decalled later on.
I just wanted to know if a full wrap was possible... which as you can see...it was




to be continued


Masks, paint and decals, inventarise what needs to be done.

Awesome stuff, indeed - looking forward to the text, also. As a former 2D graphic designer, I'm interested to learn more about the technique and materials you use to get your ideas off the screen and on to your model. Hope you include some info on how you did the wheels and tyres, too - they really set the car off nicely.

Tamar,

Amazing work, as already said, looking forward to the text.

Did you use the white masking so that your decals worked?

Hello Jay, Pete, Colin
SItting in the garden with the laptop, doing a bit of male multitasking this afternoon.
Trying to keep one eye on the telly (Max Verstappen @ F1 GP silverstone) and the other on the street across my house where the Tour de France will be passing by this afternoon. Its a real circus out there.

This thread is meant to be an addition to Richard's excellent tutorial "How to Relivery a Slot car." in the scratch build forum.
And although it does help to have a graphic background (racecars basically are very fast moving billboards
) you can accomplish very good reults with just a good eye for detail, a steady hand and a good bit of determination. But you guys already know that.

I'll try to include some of my experiences for the more "graphically" advanced members (creating vector drawings and color managment for decals)
as well as for those who just want to add a bit of realism to their RTR cars (basic detailing with simple tools like markers, tape and a bit of paint)

@ Jay: if clothes make the man, wheels make the car
First thing I always do when I start a project is make a set of wheels
If you like the wheels on the pictures I've posted so far...you are definitely going to like this thread. This was just a starter with a bit of paint applied and some dots done with a white marker.

@ Colin: Yep, that's the good eye for detail I was referring to

I actually am using this build as a final test for the decal sheet we talked about, when done the files will be send to you.
But it did mean I had to be quite precise in masking some of the areas. With decals that have the white printed you won't need to be that precise, and if the white is really opaque, you'll hardly need any masking at all.

Ok the Sliverstone grid is lining up now....gotta go

with kind regards
Tamar

So Verstappen was out within the first few laps and the Tour de France guys rushed by in 30 seconds

So I've had time to add some text to the post.

I will keep updating the O.P. with new texts and images and will post when there has been a major update.
I've just attached the body templates as a PDF file for those who want to use them to paint, mask or make decals for their C6R.

If you guys got questions... I will also answer them in a new post.

with kind regards
Tamar

p.s. @ Jay: Have to finish a lot off text before I get to the wheel detailing stuff, but here's a teaser image to keep you happy

Brilliant to read the updates and explanations you've added to this thread, Tamar - oh, to have your super-special mod-powers and be able to edit an OP!


I've had no problem in the past with the middle and final parts of your process, preparing the vector/bitmap graphics and applying them to the bodyshell. I used to do this on 1:1 cars (vinyl cut stuff, mainly), so the process is the same... just in scale! So, I kinda skipped the computery stuff and went straight to the eye-opening part - the work you do prior to the middle and final parts; in particular, the materials and technique to create an accurate template to work with. So, now I know what tapes to use, I think you might be seeing more than the usual sticker-bomb and 'badge-work' I've done in the past - time to try a proper wrapped livery.

I've always wanted to create my own consistent livery for the MANY projects on the go - Sideways Porsche 935/77 & Zakspeed Capri, MR Slotcar McLaren F1GTR, Black Arrow GT3 Italia... maybe even a Koenigsegg, too. Reckon you might have given me the confidence and inspiration to get things going... thanks for sharing your secrets!

And, Colin - thank Tamar... this is going to mean more work for you!

Finished the clear coat and added some details to the C6R last night, alsmost finished.
So when the sun popped through the clouds today took some quick shots.

Hope you enjoy watching them as much as I do


Will be adding text and more images to the OP over the next couple of days.

with kind regards
Tamar

Fantastic work Tamar.
I would really like to know more about the wheels inserts. And also the antennas: what are they made of and how are they going to fare if/when the car goes upside down?

A really excellent looking car, the investment and attention to detail is clear!

Further to Tamar's recommendations, I'll throw in the very capable Affinity Designer as a suggestion for anyone who wants an inexpensive vector art programme for Mac. It's about £40 in the app store, and I prefer it immeasurably to inkscape.

Well = I'm absolutely *Gob-Smacked*.
That's very profesional work using state of the art techniques.

If I could just make my own tyre lettering decals = I'de be very happy!

Gents, glad you like the car.
This was the first car I've build without having the stress of an upcoming race in years&#8230; I must say I enjoyed this build very much.

As promised I'll give some extra attention to the wheels detailing in my O.P. Mind you its very basic, common available stuff with a bit of paint.
For instance the inserts for the NSR Vette came from Slot.it, actually they are not the correct inserts.
I should have used the Carrera wheels like found onder the 458, AV vantage and DTM's or the Scaleauto BMW Z'4's but they were all to big.....work in process

And Rick, for those tyre decals, got Goodyears, Dunlops, Pirelli's and Hankook's
I'll be sending the files to Colin, you know how to find him.
These will fit most contemporary GT and LMP cars with 17 wheels , that is if you run your slotcars with decent sized fronts and rear tyres


If there is interest in them I could do some classic tyre wall lettering for 15& 16mmø.

As for the "state of the art" technologies, well maybe for the graphic work and the software, but most of it is very much "kitchen table" technology....some of it literally.

For instance Gio, those antenna's you asked about. You've probably got a couple of hundreds of them in somewhere in your kitchen cabinet.
They're black hairs I nicked from a dishwashing brush ( the missus doesn't even notice they're missing)
They're very flexible, I secure them on the inside of the body with just the tiniest dab of shoe goo.
And should they happen to come off...there's plenty left to replace them where they came from.



The thing is, I accuired my skills in a period when there was hardly any aftermarket stuff on the market for 1/32nd scale available, so I learned to make stuff with what I had laying around.
Back then having a BW laser printer was about as much "state of the art" as having a 3D printer is now...so who knows, what we'll be posting in ten- twenty years

with kind regards
Tamar

Hi Tamar
thanks for the info about the antenna...I thought about using a plastic brush for making them but the idea of going through the plastic and gluing them from the inside is really cool.
With this thread you made me go back to my scaley C6R #50. It looks very similar but there are some small difference in the logos.

This is a marvelous thread Tamar and I hope to be able to work this way one day. At the moment I can only work in 2 linear unwarped dimensions using Powerpoint. Can you print white images?

Hello Gio

Your Scaley C6R is exactly the same car/chassis as my NSR, but has the livery as raced in 2011 (as opposed to mine which represents the 2013 car)

They used this theme for 3 years, here's their 2012 entry.


The Scalex is one of the nicest liveries out there so when you do go in and add the antenna's...here's a small tip that will prevent you from scratching the roof by mistake.
Put a piece of masking tape over the area you need to drill the hole in and mark the spot. Its not the first time that a drill bit slides away and leaves a big scratch on your clearcoat.
This piece of tape prevents that.


Hello Andy
Well 2 dimensions is a start, and will work for most decal jobs. And no I can't print white, that is reserved for those who have more professional printers at their disposal.
However, depending up on the livery and the base color of the car.. you can get pretty good results with transparent decal sheets (like I've used for some on this Corvette)
Or use white decal sheets and add a background color that is matching your base car color (like I did for some of the smaller logo's in the C6R)
I'll cover that part in more detail in the updates of my O.P.



with kind regards
Tamar

Hi Tamar
Thanks for the tip about poking a hole for the roof antennas.
Looking forward to more updates.

One more thing Tamar: what have you done to the interior?
I know that you background is model airplanes - similar to mine - so making the cockpit right even if is going to be enclosed by the canopy is a must.
For instance, I noticed that the steering wheel of NSR cars resemble more the one in a truck of the '50s than the one fitted in a modern sports car.
Any thoughts there? (I know that is not visible when the car is zipping around the track but still...)
