Rotational stability. The machined piece of plexiglass will be mounted 3 to
4 inches above the bottom piece with stand offs. The holes for the
capacitors will be drilled oversized so as not to induce any stress on the
caps. I'm doing this because I'm planning to have the finished product
mounted on castors. I see the silicone as being a translational anchor that
may not be able to stand up to the torque induced by the caps over years of
use in a semimobile fixture.
BTW Your arguments for the consideration of the 8171 are quite convincing.
