Unlocking Drill-Press Depth-Stop Nuts
Drill-press depth stops that consist of two nuts and a threaded rod have an annoying habit of locking together. Although tightened by just finger and thumb pressure, they inexplicably resist the same or greater pressure to loosen them. I solved this problem by inserting a red fiber washer between the nuts. Such washers, used in fuel lines and carburetors, are easily obtained in auto-parts stores.
