use a stainless steel bolt or threaded rod with leads connected via ring terminals and double nuts on each end. Calibration was simple by turning the nuts along the length of the bolt and locking them down at the correct distance apart.Simple,cheap,effective, and good enough for commercial broadcasting.
TRY USING 3/16 OR 1/4 INCH STAINLESS STEEL ALL THREAD size depending on amperage hi a large dia all thread
stainless rod is hi resistance compaired to copper/ brass es use a 100 microamp movement!!
