Corvette C5-R Compuware (part 5)

First post of 2015.
A happy new year to my readers!

As I pointed out in the previous post of this build, the wheels sit too deep into the wheel wells.
With Evergreen profiles I made the suspension parts wider, so the wheels don't sit so deep anymore.

I forgot to take a picture of the final testfit, but I did make a picture of the adapted suspension elements.

Next I continued work on the interior of the car. According to my reference images, several parts were missing in the Revell kit.
The most obvious part missing in my eyes was the piece of rollcage directly behind the driver's seat.
I constructed the additional piece of rollcage with Evergreen profile and sheet. I also made the driver's head rest from evergreen sheet (the white part on top of the roll cage)

Now it is possible to attach the seat belts to the roll cage.
But to make this possible I had the adapt the driver's seat. The seat included in the kit differed quite from the seat in the reference images.
I had to trim quite a large piece from the top of the seat. The molded-on seat belts were removed and the (lightening?) holes have been added to the seat.Finally I also added some additional holes for the seat belts in the seat.

As I was busy making parts for the interior I also made the 2 mysterious boxes on the co-driver side from Evergreen sheet.
As my reference images weren't very clear the boxes are an educated guess and are probably not 100% correct. But they're good enough for me (until I find more and better reference images...).

In the meantime I also started rebuilding the diffusor. After I removed the original diffusor strakes I constructed new strakes from 0.5 mm Evergreen sheet.
After determining and marking the positions for the newly fabricated strakes, I glued them to the floor. This went rather well to my surprise. I'm even astonished at how strong the bond between the strakes and the floor is. I glued the parts with Tamiya thin liquid glue (the one with the green cap).
Only once did one of the strakes come loose when I was sanding the seam. My fault in being a bit too impatient and putting to much pressure on the sanding pad.

After I'd rebuild the diffusor it was about time to introduce some primer to the parts.
I almost exclusively use Tamiya Fine Surface Primer for this. I decant the primer from the spray can into a jar and after the primer has gassed out I dilute it with Tamiya Lacquer Thinner to the desired consistency.
I must admit that I was a bit afraid of how the body and floor with new diffusor in particular would like under a coat of primer.
In short : It was a bit disappointing...

There are several spots and areas that need some more filling and sanding.
What is bothering me the most is the small crack visible near the filled right naca-duct. Sure, it won't be a problem to fill the crack and sand it flush, but I'm a bit afraid the this crack might turn up later when the paint and/or clearcoat is on....

If somebody has a good (or probable) solution, feel free to leave a comment to this post.
That's it for this post. See you next time.

Euro Model Expo 2015

Last weekend I went to the Euro Model Expo event in Heiden, Germany.

The event was spread over 2 days. I visited on the first day, Saturday March 28th.

Just like last year the location was packed with stands occupied by a good mix of vendors and modelling clubs.

The quality of the models on show, it being on the club stands or the competition area, was once again very high.

During the day members of the Belgian modelling club KMK-Scaleworld were giving demonstrations of several modelling techniques.
I decided to visit the demonstration of Jeroen Veen who showed the public several aircraft painting and weathering techniques.

For me, as a n00b on aircraft, it was a very interesting and entertaining demonstration and I hope to apply some of the techniques I saw to my coming build of the 1/48 Tamiya Lancaster I got waiting.

It was also a nice occassion to talk to some fellow modellers.
Amongst others I had a nice chat with Sascha Müller who had a stunning diorama of a Le Mans pit stop on …

Corvette C5-R Compuware (part 2)

In the previous post I already mentioned that the moulds had seen better days as this is quite an old kit (original moulds seem to be from 2000/2001).
A direct result of the age of the moulds is the fact that the kit is based on the early version of the C5-R, more precisely on chassis no.'s C5R-001 to C5R-004.

The version of the car that can be build from this kit is the Le Mans 2003 version, being either chassis no. C5R-008 or C5R-009.

I found a lot of useful information on the C5-R on the this site.

I tried to highlight some (but not all) differences between the different versions of the C5-R below.

As can be seen are there quite a few challenges ahead if you want to build your Corvette as it raced at the 2003 Le Mans event.
I will try to rectify the most obvious differences, but won't be taking on all of them.
My original list of modifications was looking like this:
close the naca ducts (2).removing the louvres of the radiator outlet (3).increasing the radiator outlet open…

Corvette C5-R Compuware (part 9)

Getting there
The drama with the tires finally seems to have come to an end.
My suspicion that the aggressive solvent-based clearcoat triggered some sort of reaction with either the water-based clearcoat and or the material of the tires appears to be true.
My options were rather limited, so I decided to spray a new water-based clearcoat over the tires, hoping to cover the previous layer of clear and stop the reaction.
For 3 of the 4 tires one layer of clear was enough.
The rear tire with the most problems received 2 layers and that seems to do the trick. Even after more than a week of drying the clear stays flat.

The clearcoat I used was my own Revell Aqua Color mix as used previously. But this time thinned with it's dedicated thinner and applied by airbrush.
Although the image above does little to hide the imperfections I'm happy I finally am able to finish this chapter so I can divert my attention again towards the rest of the kit.

Work has finally continued on the body.
