1000 cst silicone seemed to be a recommend I came across.

the part in question are the two horizontal brass pivot screws that point into the delrin. Some say a bit of lube there is a good idea and this weight silicone is a good choice....any agreements or disagreements? seems like one get can a small bettle quite inexenpesive:

or could I use one of he several silicone based greases i already have i wonder? how critical could it be? and why is 1000cst an essential weight I am thinking

Better off replacing the Delrin inserts with sapphire bearing cups, vertical tracking will be much improved. You could try the silicon in the bearing well, horizontal damping could be improved.

I read the thread where someone seemed to source ruby bearings, but it wasn't clear to me exactly what was done. there where no pics. they said 'inserted the ruby into the bearings'. i thought the rubys where the new bearings, and instead of having threads, they where just pushed into the brass holes? i will continue to look it and try and understand. but either way I am thnking of putting a dab of this grease on the delrin dimple/hole/
