Holy Christmas fellows.... are we getting into a friction measurement war here. ?? :) Now to be truthful, I've never had use for the little dial gauge available at supply stores... but I do know how its used... at least by anyone I've seen use the thing. One measures the flange, not the shank. The jack is measured on the graphited area of the small arm... very nearly the same 20 or so mm away from the center pin as one measures a flange. For a more precise description, please visit Renners article on the matter at http://www.rennerusa.com/PDF/flange_bushing.pdf A table for reference friction levels is on page 2.
