Re: 1/12 Kremer K3 Porsche 935

Thanks Paolo, I took a look last evening and found the same flaws what you found.
And some tiny more.
Will try to use the Tamiya front window as a template to reshape the window.
Will sent some pics tonight.

Re: 1/12 Kremer K3 Porsche 935

After the first coat of filler i checked the shape of the K3 a bit more.
There are some flaws i have to convert before casting the body.





The front window needs some smoother shape around the edges.Will try to use the frame from the Tamiya 935 for it.
The naca ducts are too tiny and the intakes behind the door as well.
The rear engine hood is too big and need also an other shape.



Naca ducts are done.Need the Tamiya ones and glue it under the body.Should work fine i think.



The rear hood needs some more attention. I drilled holes into the printed body and cut it along the fins. The height of the hood is now a bit lower.I also re-bend the shape of the surface between the fins a bit.
Now i have to glue it in place and use 2k putty to get the right shape.

Than i try to find a solution for the front window.

regards Christian

Re: 1/12 Kremer K3 Porsche 935

exactly what I mean.
Beware just where exactly the upper "turn " of the main front frame starts compared to side door windows, think that line is really important and here still in common with ordinary 911 serie. Any tamiya recent model as turbo or 934 can guide you precisely.
U get exactly what I mean grande Chris !

Maybe take also a look at the big windshield transparent part now...think is worth a measure.

this car is amazing and so unique....keep on my friend.

Re: 1/12 Kremer K3 Porsche 935

Now i found a solution for the roof which makes me to 95% happy.



I also used the Tamiya front hood and only have to sand a tiny bit on both sides.



Next step will be the air intakes at both sides before i cant start with 2k putty when i am back at work in January.

regards Christian

Re: 1/12 Kremer K3 Porsche 935

Today i finished all the bodywork changes.Hope so?
Some shots of primer and tomorrow the rest.Will show some pics when its done.

In the meantime i started with the tires.
The tamiya 935 used the same tire size like the Kremer K3.So i started with them but they are very thin and wobbly.
I made an inner spacer to get more strength in it.



Thats how it looked mounted.



Should be hard enough for casting.



The mold is half filled with the tires.The rest will be cast.





Some layers silicone was added.


Now are both half sides cast and the rest will follow tomorrow.

regards Christian

Re: 1/12 Kremer K3 Porsche 935

Sorry,only poor quality smartphone pics.

















Quiet happy with the body and the tires.The original rims fits very well into the resin.
The body needs now a lot of fine sanding.

regards Christian

Re: 1/12 Kremer K3 Porsche 935

Next step was the master model preparation.
I used some nitro putty for the fine details and started with the plate for casting.





Nest was closing all holes and windows.I used some plastic card for it.





On the inside i used some way sheets to get an thicker wall for casting and more stability.Its always hard to find the best solution for a light body and a good flow for the resin.
Will see how this works at the end.





Thats all right now.
regards Christian

Re: 1/12 Kremer K3 Porsche 935

The "interior " is ready for casting now.
I got some massive edges at the rear wheel arches.I need them for the casting.But at the end they have to be removed from the resin model.Donk know how i could make it better.Cant find a better solution.
Anybody got a idea to avoid this?
Otherwise i want to cast it this weekend.Silicon and Vaseline is here.Only need to find some hours time for it.



Here you can see the massive part which is closed with blue plasticine.



Somebody could help with these problem?

regards Christian

Re: 1/12 Kremer K3 Porsche 935

for an identical issue I am haveing big problems casting my nsx bodies.
They come ...but you must study very carefully the catalyzing time of your resin.

Mine, finally, becomes ok for extraction after nearly one day (10 hours) in the mould. This means, ...one day..one body. Takes patience.

one of the many reasons those toys are pricey.

Re: 1/12 Kremer K3 Porsche 935

Now comes all together.
The body is ready for the silicone.The silicone needs some temperature before casting and the body needs some time to drying because of the Vaseline.
Patience is not my strongest thing. :roll: :roll:







But tomorrow it should start.

regards Christian

Re: 1/12 Kremer K3 Porsche 935

Think about a curb side model Chris. 1/12 tamiya Porsche becomes more and more pricey. Something easy as the little garage original kit was. Can give u pics if u need.
