I was able to take some pics today. The gray one hasn’t been cleaned up yet. I wet sanded the green one a little. There was a lot of small air bubbles in the green one.

These are 2 videos of my friend Mike Petryszak’s rotocaster. Mike does some excellent work.

Here are the 2 colored ones using the tinted amber resin. These weren’t rotocast like the first one.

The second pic is back lit from outside and really shows the color off. These have not been cleaned up yet. There’s a small line where the molds comes together but it can be sanded off pretty easy.

Here is the first rotocast! The original sculpt is on the left.

Got the second side done! It de-molded fine with no damage to the sculpt.
You notice the other half is blue. We used a quick cure catalyst so I could try to prep for casting tomorrow.

The Pour Spout

Here is the pour spout. When it is rotocast, I put the plug in. There is a small hole drilled in the plug so that some of the heat can vent.

The resin gets hot and expands. The hot air would bulge the mold if it couldn’t escape. The heat and a little resin goes out the hole.

You have to put a little zip lock bag around the plug when you rotocast it so it will catch the resin. If not, the resin will fly around the room. (I learned all this from Mike Petryszak)

Doesn’t he look so comfortable!!

Here’s a look at the clay for the mold. I need to make walls on the sides then pour the silicon. Once that’s done, I’ll pour the second half of the mold.
