Funny how last night I said, “I hope the clay I used as a barrier doesn’t cause the silicone to not cure.”

I fell asleep before I could check the pour last night, so this morning I discovered the silicone had not cured where it was in contact with the clay. The part was not damaged at all so I cleaned it up real good with rubbing alcohol, researched some clays online, then decided I would just use my super sculptey to create the barriers because one – I had a bunch of it, and two – I didn’t feel like waiting 3 days for a mail shipment of clay to arrive. I knew super sculpey would not cause problems because I used it in my early tests.

I built a new barrier platform with the super sculpey and it came out way better than that stupid clay I had used yesterday. I sealed it all up with hot glue and poured a new batch of silicone.

Later I built another barrier and wall for the humerus part. I had just enough super sculpey left to do so. After all the silicone cures by tonight I will be able to reclaim all the super sculpey and reuse it for more barriers.

After pouring silicone over the second part, I realized I hadn’t mixed enough. Strange. Did my math fail me? I mixed up another batch and for some weird reason the consistency of it felt wrong. It didn’t react well in the vacuum chamber also. I almost poured it in anyway, but at the last second decided to throw it out. Something was wrong with it. Maybe I did not measure out the two parts equally.

I mixed up another batch and this time everything went well. Hopefully by this evening I’ll have two well-made mold halves.
