Molds molds molds

I have been making molds for days now, a slow process of back breaking work for a 67 year old dude. What you are seeing here will be better explained in the video we have been shooting when I can get to it.

What is happening is water based clay laid up against the master and smoothed. Then I build up a styrene box around it and pour the first side of silicone.

Once that sets up the next day I lay up the 1630 two part polyurethane resin and fiberglass cloth for the supporting or mother mold. That sits until the next day.

Then I can remove the styrene and clay and do the second side except this time I use clay for the wall. Pour more silicone and let it sit overnight. Today, Saturday I will do the second half of the supporting mother mold and we have a finished mold.

Tomorrow I’ll take it apart, clean the mold out and make four sections castings in Alumilite for the wheel.

Additionally I have made the hub mold in silicone (sitting next to the section mold) and today I mold the center section connector shaft and spokes to the hub.

Next week I start building the actual model.

    Very, very cool. Thanks for the glimpse into the method!

    You’re a true artist, Steve. šŸ™‚

    I’ve been watching your Enterprise videos as you’ve been posting them, so this process is familiar to me from those videos, but I still love seeing pics of it.
