    Frustration and Solution:

    Good, reliable tuning and waxing information is extremely hard to come by. Yes, there are some very good videos (and many bad ones) on YouTube to help new tuners, but there is almost NO reliable independent data on Base Structure and/or Wax performance available anywhere. Glide testing is complicated, time consuming, expensive to do, and the data gathered often does not stand up to the rigors of statistics.

     

    I am beginning my own glide testing. WHEN I have data I can really trust, I will probably release some of it here. Although I will have to consider the repercussions of giving up that sort of hard-won information on a blog before I do.

     

    Look for updates here. I will add them in response to comments and questions. If too shy to write, don’t be disappointed if the blog stays a little “quiet.”  In the case of few or no responses here, my research will only be shared with a few friends and CMAC racers.


    Enjoy your Summer!

    One of the technological highlights this year was the creation of Fog Wax.  The idea for Fog Wax was hatched on the Pacific Crest chairlift- while unable to see the next chair ahead, AND ice forming on my goggle lens.

    The Problem: High Humidity combined with low temperature creates freezing fog. Skis run slowly in it, and racers GO slowly in it.

    The Solution: A unique combination of Hydrophomorificsaponaceioustranquilent agents that convert useless friction into extra speed. Skis that once ran slowly now slide freely and gently coax the pilot into more speed than ever previously thought prudent for the conditions. Fog Wax is a 3 stage kit (sometimes 4)- and there are only 4 kits in existence. It is out of production, and complete instructions for use are only available by wrote.

    The Results: Winning, happy racers, and confused coaches. Which means it performs EXACTLY as intended.

    Fog Wax Developments: There are now several Fog Wax variations:
    Fog Wax (original)- STILL the fastest, sneakiest wax for foggy conditions. NOT available at any price.
    Fog Wax Ultra- For sunny days. Creates its own fog, which can be a competitive advantage (or disadvantage for those following the racer). Several race organization are seeking to ban Fog Wax Ultra. If they can find any... which of course they can't.
    Fog Wax Full Monty- need I say any more?
    Fog Wax HARD- For when you don't actually want cloud cover.

    Yes, there have been other variations used on the hill, but these are the most common. More are sure to pop up next season.

    Well, the snow is flying so I will only be filling in the holes in this blog for a while. Current Events: I am conducting some primary research in wax absorption in p-tex bases and in glide speed of various base preparations. DO NOT expect the full research to be published on this blog. The data I am compiling is much different than I have seen published elsewhere. For those Geeky enough, we will talk about what I am learning.

    Here is a GREAT link describing the boot fitting/alignment process from Spokane's website:
    http://gossra.org/BootFittingandAlignment2006-07.htm
    I have developed a few unique boot tuning tools and techniques. I won't post too much about them here, but if you have an interest in optimizing boot settings/tuning, drop me a note.



    You probably don't think of Gadget as a Boot Guy, but I play with them almost as much as skis. Boots are even MORE critical than skis (or ski tuning), and most people only do the very basics with regards to fit, flex, function, stance, alignment, canting, ramp angle, and elasticity/responsiveness.

    This is WAY too big of a topic for me to dive into without sufficient interest in the blogosphere, but I will try to gauge interest based on the email and/or comments on this site. I don't wish to bite off more than I can chew however- so let me know what you want/need, and I will go from there.

    Oct. 29th:
    Short Plug- 2 companies have help me a TON with boots in last few years, Tecnica and Intuition. Tecnica has developed some great boots, but especially has a very supportive race-rep Dave Glotzer. And support after the sale is more important than the sale itself- in my book. Intuition has developed a line of great products that solve a lot of warmth and fit issues. Crystal at Intuition has also given me world class support. I am shocked that I don't see more Intuition liners in race boots. Maybe people are scared to try something new. Especially with the new lace up and plug liners, DON'T BE SCARED, INTUITION MAKES GREAT RACE LINERS!!

    December 17th:


    After a lot of work, Tecnica Scout plug boots grinded, punched, canted, aligned, and molded to my son's feet. They ski great, as you might expect. So, the Tech boots are done, now I start on the Speed boots...

    So for those of you experienced tuners who want MORE performance- I'm going to draw back the curtain a little bit on some more tricks. NOT everything at once, and these should not be used until you have a really good BASE of experience. Otherwise, these are like 12" of light powder over rocks: NOT good.

    Prerequisites:
    Before you get into the "Advance Tuning" side of things, you should already be:

    * Tuning/waxing everyday.
    * Have (and know how to use) files, stones, side and base guides, a range of brushes and waxes, base repair tools, etc. A fairly complete tool kit and a good understanding of their use.


    I will show you:
    * more ways to repair a damaged base
    * ways to personalize how a ski performs
    * ways to get even BETTER edge performance and durability
    * ways to optimize waxes/waxing
    * ways to spend MUCH more money on tools. I am always good for THAT one!

    So dive it... and if you like it and want even more, by all means WRITE!! I MIGHT even read your email!

    I have a saying about High End Tuning: "Everything changes Everything ELSE!" There are SO many variables to play with/ get confused with. So, after that teaser, let's talk about individualized tuning. 

    A good carpenter measures twice and cuts once, right? High end tuning is the same. You must have a goal in mind, an idea of what is standing between you and that goal, and an idea of where you are, and an idea of where your goal is- otherwise, you are shooting in the dark.

    So individualized tuning typically starts with video, coach feedback, and/or timing. As skiers get to a higher and higher level, they generally begin to know what certain tuning settings feel like and will be able to provide feedback directly- (USSA Phase 4 and 5 athletes).

    So, if you want to help your athlete bump to the next level, ask their coach for some feedback on their equipment setup. Not all coaches are comfortable in this area. Some coaches are experts in technique and tactics but don't consider themselves geeky enough to dive into hardware questions. THAT IS NOT A NEGATIVE- We all have our areas of expertise, nobody can know everything. If you don't get an answer you are comfortable with, take some video to another coach that you know and see what they have to say.

    Individualized tuning MAY involve changing base and or side edge bevels, changing edge finish, changing base structure/finish, binding mount, lifters, or even plate tuning.

    I am sure I have raised more questions than I have given answers... BUT THAT IS MY POINT!! DO NOT just jump into individualized tuning without a plan or direction.

    But WITH a plan and a decent level of skill, all KINDS of performance improvements are possible. And once optimized, the ski setup becomes nearly magical. Faster, smoother, more powerful etc.

    "Back in the day," we structured with sandpaper- roughing up the bases and creating drain paths for melt-water. Then came Riller- Bars, then came hand-stones. Shops used belt sanders, then moved to stone grinders- and sometimes computer controlled stone grinders. Advanced structuring is sort of the Marty McFly school of tuning: Back To The Future.

    Yes, stone grinders have revolutionized tuning for MOST skiers, but for racers at the high-end, you'd better know how to hand-structure. After all, your skis WILL sustain base damage over the course of the season, right? Perhaps even at a race... maybe even on race day? If you are going to repair bases on a short-notice basis, you ALSO want to restore/repair the structure, right? (The answers to all these questions is "true" by the way!)

    To be prepared to deal with this eventuality, you might as well learn to hand-structure when there is no pressure.   More to follow...

    Taking a very good structure and making it GREAT... OR taking an OK structure and making it Very Good is the point of this blog entry.  more to follow...

    1/07/13: I have decided to NOT discuss base polishing here at this time. I would rather demonstrate the techniques/tools involved in person.
  • 29 Oct 2012 4:01 PM | John Ellis (Administrator)
    1/07/13: This is another subject for in-person instruction. I MAY demonstrate base repair 01/12/13, IF time allows.
  • 29 Oct 2012 4:00 PM | John Ellis (Administrator)
    01/07/13:  Yes, edge polish is considered critical for speed skis. No, it isn't well understood by most shade-tree tuners. Yes, I will be talking about at my 1/12/13 clinic at Crystal. No, I will not talk about here... at least right now.
