Anyone have a source for hardcopies of older ASE standards??
I have a company we are working with that is seeking an ASE J964
"grind lead test method". As I recall it has to do with a "specified weight" on the end of a "string" hanging above the finished rotating shaft - and the assessment for "grind lead error" is made by moving the string along the shaft and estimating/guestimating how far off the surface the string bounces..
(IMHO) the machinery used in industry today has far outdistanced the old "String and guestimate" approach..BUT thats what their customer wants so they are at least making an effort to comply.
