CLEANING 3-JAW CHUCKS
This is a quick & easy way to clean 3-jaw crankshaft grinder and lathe chuck scrolls.
– Make a stubby chuck key driver for use in a cordless drill; quickly remove the jaws.
– Insert a toothbrush in one of the jaw slots, then run the drill-driver to spin the scroll while spraying carb cleaner on it. Repeat as needed until scroll grooves are clean.
– Clean and coat the toothbrush with oil; insert the brush in a jaw slot and spin scroll with drill-driver until grooves are lubed.
– Use drill-driver to replace jaws.
