For the lolz, I measured the step down ferrules in my parts bin. The minor outside diameters were:
5.9
5.8
5.5
5.4
5.3
4.8
4.7
4.4
4.0
(I have >9 of them, but there are duplicates)
Presumably each one was perfectly sized for something once. This is the porn thread, so if we uphold decent porn standards of no rattling on either end and the step being <1mm from the socket face after assembly, "every shop" probably needs to stock somewhere between 100 and 200 separate SKUs to be able to supply the right stepped ferrule for any project.
