Here is a simple little project that will save time and frustration. I finally got tired of screwing the depth stop nuts up and down on my drill press. Made a new screw and added two Quick Threading Push Button nuts from McMaster-Carr. Now I can set depth stop with the push of a button and back it off with the push of a button. Pair of nuts cost about $15.00. Works just like the push button quill stop for a vertical knee mill.
