Nothing you learn in this life is a waste of time! I'm 10yrs older than you and twice retired. I'm in decent physical shape, and would go back to work tomorrow if I found the right job.
(Don't tell my wife I said that) Not much demand for a 70yr old in my chosen line of work, so guess I'll have to be content to play with the guns I have. I have guns that I haven't shot in over 3yrs, maybe more, so I guess I have enough! Although there are many things I could do around my AO, loading ammo and shooting action pistol games make me the happiest. I understand that you enjoy working on guns, so naturally you want to learn all you can about it as well as acquire all the latest tools and fixtures to do it with. I wish you great success and satisfaction in your endeavor. Keep us up to date on your progress.
