Has anybody tried to rotocast without a machine? In yet another larp prop project, I want to create a hollow bodied alien to stick blinking lights in it. But I am having a hard time getting even coverage. Problem is, when I get close to my pour holes (which are big because they were the support pillars for the sculpture when I was making it (I didn't want to bake it in order to be able to recuperate my clay), I can't get the urethane to go in the right place without things pouring out.
Here you can see the results of my first test for the body (legs, wings and paint job will come later). As a concept, I think it has the potential to works but my technique was obviously flawed. The tail ended up with way too much resin, I had pooling problem on one side and the middle section had missing coverage. http://www.youtube.com/watch?v=Mr9blSeanLc
I know now that I should have done several layers instead of just one. But I'm wondering if it's ok to plug the pour holes? If it matters, I'm using Task 16, cast in a rubber mold supported by plasti paste mother mold. I'm a bit afraid that gasses might build up (or it could just be me being paranoid). Maybe plastic wrap with tiny holes in it?
Also, has anybody tried to stick two pieces of fully cured urethane together. I know there are some specialized products out there, but I'd rather not pay $30 to end up with a gallon of glue. Would run of the mill polyurethane glue (from the home hardware store) also work? This way I could create "patches" and glue the critter shut once I've put my electronics inside.
