Maybe we'll see this at Wonderfest!
I just want to see more progress pictures. Building the AMT version, what a chore.
I'm learning a new (to me) casting technique and I'm starting over on the molding process.

the rein casting trick with the plexi glass, how do you avoid trapping air bubbles in??
Why are you creating new molds? What happened to the ones shown in this thread?
Here's how I do it, it's probably not the right way but it works for me.trooper said:

Part two. I should have edited the clips together, I'm still figuring out the software.

Rich. Do you wax or put a release on the plexi, i know on a small part its not bad. But on a bigger part that generates more heat i know i would use a release.
If it's a new piece of plexi the resin won't stick to it, but after a few uses it's a good idea to either powder it or spray it with mold release.
REL,
I was wondering - your castings are always seemingly flawless. Why are you molding up the model with a new technique? Is there some advantage to this technique that I'm unaware of? Some limitation of what you have been doing (fantastically) for the rest of your projects? Just a chance to expand your repetoir?

i would really like to see videos or your buiding, molding up and casting. richard you have allot that you can teach people, as stated in another thread by folks this seems to be a dieing art, i would really like to see new people come on baord with you guys and make there own builds. it would be a real shame to see this craft fade off.
ive seen those, i was thinking more like showing how he does the detailing/scribing, more of a toturial. i always look for diferent/ better techniques for doing things, rel's work is simply awsome, there is allot of things from him many of us could learn
I'm making the molds and jackets for the engines.
With the matrix technique you can control the exact thickness of the rubber, rather than brushing the rubber on where you might get thick and thin areas, so it uses a lot less rubber. Also, if you need to make a new mold, you don't have to go through the whole clay up and mother mold process again, you can use the same jacket over and over again.

ive always liked this process better, i remember the first time i saw it was in the sci fi models magazine in the issue where they were casting the original enterprise D
very coll tech.
nice work rich
What kind of clay are you using to create your void? It looks water based, right?

Nick, it's waterbased yes. Specifically EM210.
Here's the Ultracal30 mothermold.
Molding the main body. I decided to make fiberglass mothermolds so I can see where the rubber is going since it's semi transparent, then if there's a blockage I can drill a vent hole.
Here's the bottom already finished.
The top with the fiberglass layer over the master with 1/4" of clay.
After removing the clay put the fiberglass mothermold back in place, drill vent holes and cut an opening to pour the silicone.
After the silicone has been poured, plug the holes with screws.
