I don't hone cylinders because all mine or either chrome or nickasil.  I smooth them up with a little fine emory cloth and some wd40 or Dexron

Well just to mix it up.  I do hone mine and I use 320 grit when I do.  The only time I hone is if the cylinder has had damange to it and I am trying to clean it up some.   I use a variable speed drill and work it up and down at a very slow speed.  I then do the same in reverse.   I only do this about two or three times so as not to damange the cylinder plating.  Oh one other thing is I use 30w engine oil on the hone before putting it in the cylinder and then clean it in an ultrasonic cleaner to get all the grit and oil back out of it.

This is a ball hone I am referring to so that there is no confusion.

Which ultrasonic you using? Heat or no?

It is a L&R not heated.   I collect American made Railroad Watches for the last 40 years and got into restoring and repairing them about 30 years ago.  So I have had this ultrasonic cleaner now for about 25 years.  It is big enough that I can do about 2/3rds of a cylinder at a time.

You have to watch those plated cylinders now because you can grind right through the plating before you know it .People are under the impression that the hard nickle alloy process which is often refered to as nicosil is so hard you can't go through it are sadly mistaken because you can  and I have .

Generally speaking if you get a plated cylinder cleaned of any tramp aluminum if there is any will seat the rings .It might take some run time but they will come in eventually .
