During lunch, I tried a new experiment in casting bones in the arm.
Like the previous one, I made up a silicon paste to set the bones into. But I did this in two passes, hoping to get a better skin depth above the bone. I put in a layer in the mold and then, while this firmed up, a second layer on the bones and then set those into the mold. We'll see if it helped.
Then I made a batch of fluid silicon, to try and fill in gaps around the bones.
Then I made another paste to fill to the top of the mold, on both sides! Then a final fluid silicon which I poured into the palm area and around a bit.
A quick flick of the wrist and the top of the mold is in place, and I'm duct-taping them together. My handy tie-down straps for the truck ratchet the mold together tight.
Later, such as tomorrow, I'll make more silicon and fill up the rest of the arm. Then I'll see how good/bad the result is.
If this one sucks, I'll make a solid silicon arm without bones and paint the outside. I *know* that will work; it just won't be as nice.
As for the school, I just learned that there was mis-communication between me and Park University, that may cost me 30 credits (ten terms, over a year) of time in my degree... mostly because they have a drop-dead deadline (one time only) that I thought was a cyclic deadline (like all OTHER deadlines, e.g. testing and registration, at the school).
So I'm a bit pissed off right now.
