I am making a new mold of the wheels for the 67 Eleanor Mustang.
Here is the first mold I made out of another silicone that I tried. this was a mold that I started the pedestal idea but not thought of the pyramid idea. This is a mold that was also put in a oven and warmed at 170 degrees as this is the minimum that my oven will heat. The mold feels dry and baked. It just does not have that silicone feel to it.
Here is a typical succession of the wheels being prepared for the mold making process. Top left is the wheel untouched. Top right is a wheel that I inserted some thin plastic from a food storage bag. Lower left is the front view of a wheel with the plastic that you can see. And lower right is the wheel on it's stand.
And the usual boring pic of some parts that have been boxed in and tagged. BUT WAIT!! OH GOD, this is exciting!
I put some scotch tape over the wheel openings to keep silicone from being introduced to the spoke detail. I could say that I am attempting to streamline the mold process. That's a sort of joke to me that when a company or especially a financial institution claims they have streamlined an application process to get you through it faster usually means they have added more steps and more hoops to jump through to give you what you came for. Anyway, in all actuality, the reason for this is that the lower right wheel won't stay seated down on the clay. WHEW! 
Here is the mold with 100 grams of silicone poured in. It didn't quite reach a couple of the wheels so I took mt spatula and pulled some up to the wheel sides to put at least a skin of silicone on. Once cured I can pour more silicone on and put it in the vacuum chamber to try and make certain no bubbles will be present next to the detail. We will soon see how much silicone will get pulled down under the spokes.
And a really exciting pic of the tape removed from the face of the wheels.
