Thanks!
More done on the P2.
I'm making the master with the B&W/mid type fins. I'll have to cut them out for metal fins.
First set of shells from the new molds. I'm spraying paint into the mold instead of using mold release, it works great. It doesn't bond to the silicone, but the epoxy bonds really well to the paint.
Sanded down to proper height.
The glass was pretty thick on these, next set is curing now and is thinner. I'll use these thick ones for a static build.
If you look at the shells I made yesterday, you'll see one has a yellowish color. That one was made with the fast curing epoxy, 6-8 hours. The working time was too short for that one, it got too thick and I had to make a second batch to finish. So I used the slower 10-15 hour for the other one. It has no color, and plenty of working time. Set time is no difference really, I just leave it overnight anyway.
I realized I have some of Smooth-On's casting epoxy that hasn't been opened yet. I used it to cast a bezel, it needs 24 hours to cure. I used Task 3 resin for my first few bezels, but the high humidity is making it foam up. The epoxy seems to work just fine, so I'll use it instead.
