The Stovebolt Site Forums The Shop Area Engine Shop Dressing rocker arm tips.

I used my floor model belt sander. I set the table 90° to the belt, then set the rocker on it’s machined side shoulder where the shaft goes thru. Being careful to keep the shoulder in contact with the table, I lightly touch the belt rocking it back and forth trying to match the existing contour. Checking often and only taking off enough metal until the groove was eliminated. I followed this up with progressive grits of sandpaper to polish it up.
