The hone operation is used to break the cylinder wall glazing. This glazing only is present in steel cylinders, so in our model engines does not apply, except some seldom products that still use steel instead of aluminum..
For a hone, any three stone break cylinder hone woll do.

I found the ring replacement thread interesting. Are you guys using a hone on the bore when replacing the ring? What type of hone are you buying, is it one for auto brake cylinders? Perhaps a smaller hone for the 40 size engines and a larger one for the 90 size?
Also, is anyone using diamond paste when honing the bore? I saw this trick in RC Report magazine a while back..... said the cylinders were very hard material and difficult to get a good cross hatch hone job without the paste.
Thanks,
Ernie
