Dave - I guess my comment might have led you to believe that I have a tough guy mechanic attitude which just isn’t the case. I have over-torqued lockrings, but it’s easy to back off and the issue of over-torquing isn’t dire like with over-torquing a threaded bb (I always use a torque wrench for that).
Be that as it may, most (not all) bike mechanics I’ve met are not tough guys looking to prove a point. My aim with my comment was to share my opinion that most hobbyists spend too much time faffing with tools and buying tools when that often isn’t needed/is overly expensive.
