When I am practicing my beloved hobby of turning, I find my best faceplates and chucks are often hard to remove because their machined surfaces fit so precisely. And smacking them to break them free, even with a rubber mallet, is enough to cause me major indigestion. My solution is simple: make a large washer out of the plastic lid of a coffee can or whatever. Cut it to size, install it, and you’ll find the chucks and face plates still seat properly and safely, but are much more easily removed.
