Title: Asymmetric runner grind profile Post by: Maxim R161 on March 03, 2019, 07:33:03 PM Hello everyone.
Through my entire first DN racing season I was suffering with poor side runners grip. Major cause of it is mediocre edge maintaining. I have a lot to learn in this department. However, aside from that, I am long curious of why exactly asymmetric grind profiles (chisel profile in extreme) do not work (or everyone would probably use em). My possible pros and cons suggestions are as follows: + we want side runners to hold in one direction each so why use symmetric profile on side runners at all? + chisel grind seems to be waaaay easier to execute and maintain + asymmetric grind could probably have broader angle than symmetrical without compromising grip and thus have less friction - this is unconventional and scary and everyone is fine with symmetrical so just go practice sharpening)) - chisel runners could simply go apart from each other due to unbalanced ice pressure (my major concern) - chisel shape could behave poorly as (if) negative camber develops with plank bend under load. probably not so much of a problem with less radical asymmetric shapes Any thoughts are appreciated.

I have seen older plate runners that were ground asymmetrically. I have no idea whether or not they worked or were fast, etc. etc. Perhaps somebody with more experience would know more about what happened.
