Proper Use of Truing Sleeve:
It is essential that honing tools be kept accurate and true, same as any other precision tool. The stone and guide shoes must remain parallel to each other and parallel with axis of mandrel. It is also important that stone and guide shoe be radius-ed to approximate diameter of work to be honed.
This is especially true when job being honed requires good surface finish or high accuracy, and for smooth operation in bores.

Special Note: It is important the truing sleeve is rotated 180 degrees frequently so that each end of the sleeve is worked, preventing the sleeve from developing a taper.

Portable Hones:
Truing sleeves can used by holding in a stationary vise between (2) pieces of soft wood. Apply a good coating of honing fluid with a brush and remember to flip 180 degrees for proper care of sleeve.
