Can I set my own bindings?

You see, this is why we are having trouble communicating. When I see the equals sign it means something specific to me, i.e. the things on either side of it are the same. Obviously, it means something different to you. Likewise, the terms FORCE ENERGY TORQUE etc have very specific meanings to me, but you are bandying about these terms without regard to their standard meaning in physics - that makes it rather hard to have a discussion. Actually I'm trying to understand the physics/mechanics meanings of the words. I'd like to call your attention again to the last URL I posted with its explanations of WORK and ENERGY. You keep erasing the URL without commenting on it. It would be helpful to me if you did comment on it. It will also clarify what I was getting at in the part of the post you did leave. http://hyperphysics.phy-astr.gsu.edu/hbase/work.html It's like trying to parse something like "I had my bindings waxed and now the moguls don't hurt my feet when I schuss across the hill in a parallel stem-christie wedge turn." It's hard to follow what the heck the person is on about. //walt |

VtSkier wrote: a) did you read it? I did. Look, this is only my experience. I have my bindings professionally adjusted. My guy has an expensive tool that measures torque and force. I want to catch air and not have a premature release. When I turned 50, they turned my DIN down a notch. I have knees that work. I like walking. I've trusted this guy with my binding adjustment for 30 years, since he moved to Wyoming. I don't have a cute tool to measure my binding function. He makes sure they work exceptionally well. I've seen young guys on crutches who turned up their DIN and paid a dear orthopedic price for that. So answering the subject header, yes you can adjust your own bindings. I don't and I just told you why. The whole "Work", "Force", "Kinetic v. Potential Energy" thing really isn't relevant to binding function. You can't adjust bindings correctly with a torque wrench in the garage. Pro's have the tools to do the job right. Maybe Walt wants to come out and play on the subject of Elastic Energy Storage in snowpacks inclined from 30 to 45 degrees. -- According to John Perry Barlow, "Jeff Davis is a truly gifted trouble-maker." |
