Why are you roasting it like a chicken?

The hull is cast from resin and was warped by 10mm at each end. The heat makes the resin a bit soft, so it will keep the new shape.

Ben M
Wow, that is a lot of work to fix. How long do you keep it in the oven?

Sven Schönyan
Interesting! I´ll keep an eye on it!

Michael Kohl
I like that one. And convincing weathering of the oven too. 😜

@Ben: Well, I guess that is the price you have to pay, if you want to tackle these kind of kits. I think it was in there for maybe 1,5h. Just long enough to make sure the whole resin gets to temperature. And then you hafe to slowly let it cool down.
@Michael: Don't tell my wife 😜

So you roast it at 90c for 1.5 hours?

Ingmar Stöhr Autor
Well, now that I think about it, it was more 80°C, but yes, for about 1,5h and then I left it in there till it cooled down to room temperature. The picture shows the cold oven. The red needle belongs to the red scale and the black needle to the black scale. So the temperature in the pic is not 90°C but below 30°C! This picture is some weeks old and I also was briefly mislead... I would not try this method with injection moldet parts! Resin does not melt in the same way as styrene does. It just gets a bit softer at these temperatures.

interesting idea, I do not know if I would have dared to do it, even with resin (certainly not with plastic). I read about using hot water, but I guess that the oven makes more sense in this case 🙂

Ingmar Stöhr Autor
Well, I had no choice but to try something. 80°C in the oven is not very different from hot water. It only takes more time. And it worked just fine.

Hello Mates, after a longer break I finally found some time to progress on my Harpers Ferry. Some larger sub-assemblies are finishes and received their base paint. I hope to continue with the build during May.

Very nice so far! 👍 Looking forward see the end result!

Some more progress. I managed to assemble the main mast with the SPS-49 radar and also designed replacement parts for the Phalanx CIWS, the RIM-116 launcher and the Satcom Antennas.

Spanjaard
that phalanx is awesome!

Wow, the mast and Phalanx are looking very neat and tidy, awesome work!

Do you mind sharing/selling the files you made? I'm also taking mine out of its box and going to start fixing the warping issue soon
