Reply To: Cylinder Honing 1960 Lark

[Mossman747]

By flex hone do you mean a ball type hone or the kind with 3 stones on spring arms?  I am using an adjustable precision hone to take about .002” of oblong wear out of the cylinder in the process.

The odd thing is, the cylinder seems to be about .0025 to .004 undersize according to the manual which lists the bore size at 3.19 in the specification section.  Earlier in the textural description portion of the manual the bore is referred to as 3-3/16 which what I am reading as the larger measurement in the cylinder so I think I can still true it to 3-3/16.
