Chrome ways | The Hobby-Machinist

If the dovetail is for a clamp, not necessary. If the dovetail is
a sliding dovetail, yes; stoning (or even peening) will leave 99% of
the sliding surface untouched, but leaving the burr can cut into
the mating surface if it's softer than chromium (and most all
metals are).
Clean off any oil first, and flatten your stone before applying it.

If you have a dead-flat cutting insert or HSS blank, sliding it over
the burr will let you feel when the defect is gone.

are there any concerns about cutting thru the chrome on the surface?
never heard of peening

When you use a flat stone you will feel it CUT on the high spots. When the the high spot(s) is/are down, the feel will change to a smoother glide (little to no cut). When the feel changes, stop stoning.

Watch this video to learn about Precision Flat Stones and the "feel" I speak of.

thanks for the reply but that is not the question on my mind, the chrome is a plating on top of the base metal if i use a stone what happens if i cut thru the chrome and now have interrupted chrome plating? will it delaminate?
