I’m new to quill stems and had some questions. Thanks

1) When you tighten the top bolt is there a general torque spec? I have the Velo-Orange quill stem with removable faceplate. I didn’t notice a torque setting on the stem.

2) Also, for my understanding, if you overtighten does that damage/wear down the bearings like non-quill (e.g., top cap bolt just snug, whereas too tight or too loose not good).

3) For fit reasons, I may switch to something like the VO threadless stem adaptor and traditional stem(s). The bike (Rivendell) has a 1” threaded headset. Is it just a matter of removing the old one and putting a new one in, tightening to spec?

4) Whether the quill stem or the threadless stem adapter, how far down can I push the stem into the headset/head tube before tightening it? I know there is a minimal insertion limit but is there a maximum?

5) Bonus question and nothing to do with stems. When you put an aluminum seatpost (Thomson) into a steel frame (Riv with the seatpost bolt through the frame, no separate collar) do you grease the post? I initially had slip with the stock post and haven’t pulled it out yet to see if it’s greased. I was curious as to whether a fibre paste (with grit) would be good.
