Something new here.
In the last days I was working on a new front axle as the old one was not good enough and could be improved in different ways. I'm still working on the fu..ing small axle journals. Pics will follow when the axle is finished.
But I was also working on some adequate tyres as the original herpa rubber tyres are too hard for TTTT.
I used the same two component silicone for the form and the tyres. You can see the steps in the pics below.
1. sanding the original tyres flat on the inside, so they can be glued without a gap to the bottom of the form
2. filling the form carefully with silicone (make sure that the small details like the tyre patterns are well filled)
3. remove the silicone form after drying
4. treat the tyre forms with a form release agent (?) like talcum powder
5. fill the tyre forms carefully with the (black)colored silicone.
6. remove the tyres after drying.
I had some problems with coloring the (white) silicone. The first try with usual black wall paint missed completely because the silicone didn't dry out. And so was the the second try with the powder of a carbon pencil. It wasn't dry after two days. I've lost interest after that and just let it be. After 5 days I had a look again and it was dry!
It was difficult to get the tyres out of the form after so long, but finally it worked and they do not look so bad I think. It's just that they are rather grey than black, but I'll work on that the next time
