Tapered stones and guide blocks result when
honing without enough stone pressure or from
improper stroking in a tapered hole. To correct,
keep stones cutting by frequent adjustment to
maintain firm stone pressure. When honing a
tapered cylinder, localize the honing in the small
part of the cylinder, gradually lengthening the
stroke as the cylinder straightens. Tapered
To obtain best results in bores from 6-1/2" to 21" ( using part # CAN 218 A) in
diameter, it is necessary to use a holder support with large bore hone). When a
holder support is used, the hone operates as smoothly and as free chatter as
when honing smaller size bores.
Truing Instructions. It's recommended that when close tolerance work is
required, a truing sleeve be used to true the hone before use. After selecting the
correct truing sleeve for the diameter required, mount the truing sleeve in a vise
and hone in the normal manner, maintaining a constant steady stroke. Be sure to
allow the stones to go through the sleeve for about one inch at both ends of the
stroke. Apply honing oil liberally until the entire surface of the stone contacts the
For better finish...
Increase honing speed. Decrease cutting
pressure. Reduce stroking speed.
For faster stock removal...
Increase cutting pressure. Increase strok-

For longer stone life...
