Now they gotta learn what starting a forum is all about muhahahha

Thx Adam for running a test about it. And thx Paul for the details he gave us.

I have a question tho:

Paul said: Sealing the material; actually getting a non-stick material to apply it to, so it can be sealed and frozen is trickier than you would think.

I remember from a previous post i cant find back that Paul or Matt said Elastifilm would stick to direct contact with epoxy, while the "usual" non elastic would not. So if I'm right, thats the answer to that question?

Hi Paul

I had considered the thermal expansion of the silicone but I was under the impression it was negligible. I was banking on it being negligible actually. I've made my moulds in such a way that if there was any expansion it wouldn't fit the phone. I'll have a look and the specs of my silicone again to be sure. If it does expand then I might have to give this up for financial reasons. Fingers crossed.

Ok I looked it up and I got "20 x 10 to the negative 5 cm/cm degrees celcius". So basically I put it in the oven and measure it myself.

Sure Zekewarg but I think I need to start a new thread for that. I've already steered us off topic once in this one, sorry about that everyone.

Do that Adam..

Yup, would be great.

Ok guys I've done the new thread. It's called RTV2 silicone for moulds.

To answer my own initial question...

I found a guy who makes all sorts of car parts with all sorts of resins in his kitchen oven. He said he's been doing it for years and he's still alive and well.

Hi Paul

I gave the oven method a go and it worked out surprisingly well for my first attempt. I put the silicone male and female in the oven together instead of tooling a new rigid female. To counteract the female expanding I boxed it in and so it could only expand inwards and help stop the male expanding. I did still get a few minor voids but it's progress. I'm going to tweak it and try again tomorrow.

Also, I took your advise and put big cuts in the weave near the corners and I think you have fixed my wondering weave problem too, thank you so much for that.

Fingers crossed it will fit the phone as well as the room temp covers do.

Hey Adam,

Glad you're making progresses. Could we all ask for a few pics ?

Sure Joe, here are some pics. These pics are of the 1st cover I made in the oven. I tweaked what I was doing but the second oven cover was actually worse. Trial and error I guess.





Imgine that once it's trimmed down and painted with clear gloss. I really don't like the plain weave but it was free. I'm hoping I'll be able to get the twill as perfect as the plain, when I get some more.
