Rigging.
This is the part of the project, where scratch building will be required.
Revells parts are completely unuseable:
Real life picture:
I discarded the revells parts altogether, and designed the "mother" isolator from 2 separate oval brass discs, and after sloting each of them half way through the middle, soldered them together.
My friend from Poland promissed to make 30 of them from resin, using the "mother" to make mould.
