I just pulled up a Official Monarch works card for EE 41253. On the drawing for the spindle nose there are 3 specs. Face runout, Taper runout, Cam action? They show American Standard @ .0003 for all three categories, Monarch Standard @ .0001 , and This machine, all three at .0001. Spindle taper has its own category runout... Monarch standard .0001, This machine. .0001. If I could easily pull up a pic of this I would. I found another scanned Works record card, but It didn't have the Ser# ,( it may be mine), and show the same Monarch
[email protected], but on this specific machine , the taper nose and inside taper measured at .00005
