Bridgeport mill quill lock problem

Good day
I recently saw a video where the guy used a different approach to stop the quill lock from tightening itself, but now of course I cant find it. he remade the shaft and the rear threaded brass shoe and threaded the shaft and shoe using left hand threads which reversed the direction of locking from clockwise to counterclockwise. Has anyone done this or heard of this being done?
Thanks
