French Clock Restoration of Click Spring 87

I searched YouTube for video advice on how to rejuvenate tired springs unsuccessfully. So I have made this video on how I restored a tired click spring on a French Clock, to work once again by:- annealing, hardening, polishing and tempering it. My main source of advice was "Heat Treatment of Steel Pt.1; hardening, tempering annealing and normalizing" by Thatlazymachinist on YouTube, from which I worked out the procedure for my video and for which I am very grateful. Thank you - a great video to study.
