BI1NIZ I've reviewed several structural drawings and some product specifications for "Eightwood." The main question is whether it's necessary to keep the main beam isolated from the vibration isolators, or if that's not important.
BD8AHK Insulation may not be necessary, as described above, where the voltage at the center of each unit is zero. When designing in practice, whether to use insulating materials for the beams will result in slight differences in parameters.
