Is a turboencabulator appropriate for this application? That may solve the multi-formic response requirement for stability while maintaining the required articulation and stability you seek. The original device had a base-plate of prefabulated amulite, surmounted by a malleable logarithmic casing in such a way that the two spurving bearings were in a direct line with the pentametric fan. The main winding was of the normal lotus-o-delta type placed in panendermic semi-boloid slots in the stator, every seventh conductor being connected by a nonreversible tremie pipe to the differential girdlespring on the 'up' end of the grammeters.
Sorry I couldn't resist.....
