How to ground a high-end Turntable

Hi Everyone, 1st post here as a DIY-er,

I need to run a ground wire from the bottom spindle of my turntable (TT) platter to dissipate electrical static charge. The very top most aspect of the spindle assembly is the record spindle which protrudes through the TT platter (the revolving portion holding the record) and sticks through the vinyl record hole. This short record spindle terminates about 1/2 inch into the upper platter. The platter itself is 20 lbs of solid aluminum.

Below the short record spindle is the vertical stainless steel (SS) rod shaft of the spindle bearing, a separate item in line with the record spindle above it. The top of the SS rod shaft has a SS ball bearing that seats into the upper female bearing (a sapphire plate) directly in line under the record hole spindle.The SS spindle bearing rod/shaft is held within the platter by an aluminum bearing housing and inner brass bearing retainer (race). This upper portion of the bearing housing is a circular concentric layer from outside inward: Aluminum platter, aluminum housing (inserted into the aluminum platter), brass race within housing, and SS spindle shaft, within the brass race.

The bottom of the SS spindle rod/shaft seats (held motionless) into an aluminum housing (no brass race retainer here) that passes through the plinth (the plinth is composed of layered metals: steel & aluminum, and wood acting as the main structural base of the TT) and held in place by a SS nut at the bottom of the plinth. The SS spindle rod/shaft seats (bottoms out) about 1/2 way through the lower aluminum housing in the plinth.

The lower aluminum housing is 1” in diameter and held in place by the SS hex nut. There is a SS 3/8” bolt that is taped into the center of the termination of the aluminum housing on the bottom of the plinth. The SS nut can be removed with the bolt in place. This bolt is meant to be a site to connect a ground wire.

My questions arise from how no one on the TT forums question wrapping a copper wire around this bolt and terminating the wire to the stereo systems ground source.

I understand that there is a process of galvanic action occurring here that no one addresses. Is it insignificant?

We have essentially aluminum that needs to be grounded, a bearing shaft of SS inside a brass retainer in the upper aluminum housing only. The SS bearing shaft then terminates into a aluminum.

Can I use a copper tinned terminal loop to the SS ground bolt on the lower aluminum housing? Do I then use copper or SS wire from the terminal loop to ground source? Can my ground source be a copper or SS grounding rod?

What about soldering the wire to the terminal loop, anything special needed here as in solder and type of metal loop?

I have tried to upload 4 pics for added clarity:
#1= Upper platter female bearing (contains sapphire plate) view from bottom of platter.
#2= Top portion of lower aluminum bearing housing from topside of plinth, SS rod/shaft removed to side.
#3= Bottom portion of lower aluminum bearing housing, seen from bottom of plinth
#4= As #3 with SS hex nut & bolt securing housing

Thanks for any help in answering these questions about grounding my turntable, and sorry for the length-
