A picture of the finished chair with our Jedi sporting some lovely stockings. hee hee.

As you can see, when the chair will be placed on a raised platform (like the actual movie set was for the puppeteers) you will not have to ruin your figure to make him sit. He will stand right through the chair and have fake legs do the sitting for him.

NO NO NO not Greedo legs ! ;P After molding the chair, my next step is Sculpting every Jedi's legs. Eechawanna.

This chair is a bit more complex to mold. I must find a way to divide the chair in 2 halves so that the mold will easily come apart and removal of the resin cast won't get stuck.

The white lines indicate the most simple division that should do the trick.

June 17, 2001

Here is a view from behind. Having the division in the center of the tubes should also facilitate the sanding of excess resin that reveals the molds joint.

Now that I know where I want to seperate the mold, I must make a division wall in plastiscine that will prevent the silicone from attaching to the back half of the chair.

The holes all around the side are made to "lock" the 2 halves in place and prevent them to slip during casting. That would be bad and give us a deformed chair.

Next I build a simple box shape out of carboard and spray the insides with release agent. I can then use my trusty por-A-Mold and pour the Silicone mixture into the box.

The next day I flip the box over and use my Xacto knife to remove the bottom of the box.

June 17, 2001

This exposes us to the bottom of the chair and the plastiscine that we used to cover the back half of the Silicone mold.

June 17, 2001

Carefully remove all the plastiscine from the box. What was plastiscine will be replaced with Silicone, giving us the 2nd half of our mold.

June 17, 2001

Now all the plastiscine has been removed. Spray Release agent and let dry. you dont want the 2 Silicone halves to merge into 1 big cube and never get your chair out.

At this point if that happened to me I would cry at the thought of starting over again. LOL.

This is what my silicone product looks like. It is called Por-A-Mold and made by Synair. it is a 2 part mixture.

Measure equal part in seperate containers...

June 17, 2001

...And pour into a clean bowl. This is what the 2 parts look like before mixing.

I use a regular wisk to stir things up. the secret is to make slow moves as to limit the amount of air bubbles.

When the mixture turns an even color of blue we are ready to pour into the box.

June 17, 2001

Now pour the mixture into the hardened first half of the chair mold and go to bed :)

In 12 hours we will be able to open the mold.

June 17, 2001

Well here we have the finished mold. As in most of the time, the original chair got destroyed in the removal process. So make sure you make your mold seperations correctly or you will have a sad and nasty surprise.

Now I am ready to make positive resin copies. woo hoo :)

June 17, 2001

Mixing 2 parts of Por-A-Kast into the mold gives us the final Jedi Chair B.

And here is what the chair looks like painted. Now we are ready to custom our Jedis.
