Found another site that I could navigate and ordered some stuff.
Well, having had to go back to basics I have been working a little on the prints. I did a little filing of the excess on the shins a while back, but didn't do anything on the surface of those, and took a long break due to not feeling well at all. It's a little better now, but still a long road ahead. However, yesterday I decided to start working on the chest armor - this time on the surface - and started sharpening the edges. Basically the exact same thing I previously did on the work masters, but since this is a much harder material the work progresses much better and I don't have to worry about holding the pieces and getting the surface gonked up with resin dust and pressing it into the surface with my clumsy hands - the material just do not allow it, which is perfect. I wasn't entirely happy last night when I stopped, so today I worked some more on it with a different file and the finishing sharpness is so much better. I'm pretty pleased. There's just one tiny place where I need to go over with a file again tomorrow and then the surface is done. Then I'm going to file the edges, so everything gets nice and clean for molding, eradicating all those scanning and assembly flaws of the digital model.
The reason I had to go back to the prints, even though it's setting me back to about three years ago, is because the work masters turned out to be slightly smaller than the prints and not as sharp, and my work on them had warped them, so I had to start over anyway and might as well do the work on the prints instead. I had previously been hesitant to work on the prints, but having worked on the master casts I know what I'm doing and what works best to achieve what I want to do, experience I wouldn't have had if I hadn't worked on those. Once all the filing is done, the parts will get a layer of putty primer to smooth out the surface and get rid of the ridges and scan errors.
I've been really stressed over this project lately, but it's actually nice being back to work on them. Silicone and resin is insane expensive and being a noob with molding and casting doesn't make it easier. Painting is out and I have sorta come to terms with that, even though I really wanted to do it and present a fully finished piece... though, seeing as my painting skills aren't good enough and the fact I get sick from painting... well... there's no real reason to get obsessed about it.
I'm actually really pleased by how the sharpening turned out on the chest armor.
