It is proper diameter. One of few things I am sure of.
The pins don’t go in far at all. First LBS attempt (with Var 7) the mark on pin was a little groove maybe 1mm up the face of the wedge. So nothing engaged but a little triangle about 1mm on side. This held and was quiet for not quite the whole ten mile ride home. Looking at other failed pins it sure does look like a whole lot more engagement but it doesn’t last any longer.
I honestly would not know under facing from overfacing and the only thing I know to do with taper is to follow the original taper, just cut it deeper.
Hold onto those NOS pins until I get something to work with the expendable ones.
