Hi Publisher,
Thanks for the response! I do apologize for the bad grammar regarding silicon and Silicone. I do know the difference, but I also usually know the difference between then and than -- and I usually get those wrong too. But I'll try to do better!
I couldn't figure out how to post pictures here, so when I figure that out, I'll post some photos of my first experimental thruster since that (and the camera) are all that I've done so far.
