Hi Melody, I’m sitt’n here with my dad talking about the SK and what you could do to make him lighter. Maybe you have thought of this already but he says what about making the body hollow and injecting or filling the hollow part with a lighter substance so that it will not fall apart or crack on the outside, for stability or he said what about hollowing it out and using a metal like branch for the arms and other parts that need to be supported. just a thought. You have probably thought of this stuff already. Bye.
Hey Adara you missed this thread!!

Making the body hollow in the first place is the tough part.This gypum material is strong enough to not need an armature, even if the dragon is hollow.
The dragon needs to be cast with something inside of it, in place, when we pour the liquid gypsum into the mold. So, the core thing that is inside needs to be strong enough to support the heavy liquid gyspum until it sets, and then either be left in place, if it is a light plastic form of some kind, or removed some how. Removing an inner form is nearly impossible unless the form could change shape to be pulled out from the bottom…but then, how would it be rigid enough to hold the liquid gypsum?Melody wrote:AdaraSky wrote:Hi Melody, I’m sitt’n here with my dad talking about the SK and what you could do to make him lighter.

Air pressure is a pretty rigid thing when it has nowhere to escape (like a tied piece of latex) and might hold up to pressure as long as the latex or similar didn’t leak. I’ve played around the syringes enough on off days at the vet clinic to know that once you compress air so far, it don’t go no further. It’s not like sand, foam or water.
Once the cast was dry, you could let the air out and remove the latex/balloon.
I dunno how feasible that is, but it’s a thought.
