According to my book (aircraft technical book company module 17A, revision 001), "Each blade track should be
within 1/16 inch (plus or minus) from the opposite
blade’s track." I am unsure if this means 1/8" inch total.
I have an older book that indeed says maximum difference is 3 millimeter (1/8" inch).
