How To Use A Gummy Stone
- #1
I have a grey gummi stone by Swix. I have information technology because it is something you are "supposed" to accept. But, I'chiliad always meliorate at using things when I understand how and why they are used. I am having a hard time seeing how this little and soft, basically, little piece of matter makes a difference. Volklgirl, yous say to use it on edges between tunings to keep them smooth and deburred. How often? Do yous only run it up and downwards the ski edge once, twice? What? How does that piddling matter actually make that big of a departure? The kids accept had ski team practice every day this week. Should I practice it every other day, once this week? This gummi rock seems to be more of an afterthought on many tuning info pages, and so there isn't as much info. Help me sympathise my little gummi!

I may non be the best person to answer this, as I might be wrong in my utilize of the rock! But, I generally use mine after each ski day to remove any tiny burrs on the edges. I run information technology down the edges one-3 times (varies).
I take one really soft one, which is the one I usually use and then I accept another one (a swix one) that is double sided--one side is pink, the other gray and both of those sides seem much harder than my soft one. The soft one seems to do the pull a fast one on for me, then that is the ane that I use.

I check my edges every single ski solar day when I wipe them off before sticking them in the car. If I feel annihilation rough or "snaggy", that's when I break out the gummi. I apply a vigorous scrubbing motion with the gummi flat against the offending edge or a more gentle brushing movement at a 45 caste angle to the edge if there's a "hanging burr" (this is a little, teeny strip of metallic where the side and base edges meet that can be caused by striking rocks and icy chunks or from the activity of using a tuning tool on the edges).
When doing a full tune, the gummi is used first to vigorously polish the edges removing the marks and ripples left past the tuning tools, then at the angle to remove whatsoever remaining burrs.
The practiced affair almost the gummi is that past using it every 24-hour interval, the edges can be kept in good condition while removing almost no border cloth and taking very little time. Likewise, it's actually difficult to do whatsoever real harm with a gummi if y'all get a footling over zealous. ;-)

Sounds like it could be a practiced investment...
I'm waxing my skis now, simply still a little afraid to mess with my edges.
Sunds like the gummi can be used for maintenance similar the wax even if I don't take it any further mysef and have my skis to the shop for whatsoever real border piece of work.

I am like you... I bought some tuning equipment online and seriously messed up my pair of skis... now they go to the shop for everything other than waxing...

Skilful to know. I am always afraid to become besides agressively on the burrs with my diamond stones...

What did y'all do to mess them up? It would be nice to know only so I don't echo the mistake!
Thanks for all the clarifications on the gummi. I'll gummi the skis tonight, in fact.

What did you practise to mess them upwardly? It would exist nice to know just so I don't repeat the mistake!
Cheers for all the clarifications on the gummi. I'll gummi the skis this evening, in fact.
Hi there,
As Altagirl guessed, I messed up the border angle, and took too much structure on the edges with the diamond stone (and not evenly on my edges)... you tin imagine that the skis did not experience the aforementioned when I tried them after my work on them... I brought them to the shop and they were able to set up the edges, but they recommended that I do not effort doing the edges again... maybe it is simply me, in that location are more skilled people who know betterr how to do that. And for $ten edge sharpening, it is not worth the trouble.
I have never detuned my skis... not sure how I should practice that...

During my 1-on-1 tuning tutorial terminal year we used my skis to learn, and I told the person I had a 1 base/three side (or .5/3) edge angle. I assumed they had that edge because that's what the kids are supposed to have equally racers (here they use a .5/3) and I assumed all other skis did, likewise. Now I know having a two side is mutual and better for my level of skiing. For that reason, NOW I'yard pretty sure that three degrees was incorrect, and I DIDN'T have that side edge angle. They were pretty banged up so we started with filing them. Regardless of the side angle they started with, they did end up fine. I've always wondered if nosotros actually filed them completely to a new side angle or if they actually started with a three side. I have since bought a 2 degree guide, and I accept to telephone call the store and notice out how they tuned mine in November. I know the kids got the race tune, but I don't know what they did with mine.
I tuned the kids skis this week. First fourth dimension since last season, and I merely did it a couple of times terminal season. I was very nervous! Nobody skied off the side of the mountain, though, and so hopefully it all went well.
I don't take any guides for tuning the base of operations border. That withal makes me nervous.
My nine yo skis (used) were filed so much by the previous racer that the metal is noticeably thin on the edges. Patently a file-happy parent.
This week I was told I should melody the edges after every 2nd ski session. I'grand sure that means diamond stone polishing, not filing. But, with 4 kids I doubt the skis will meet that much tuning!

Have a shop base grind your skis and gear up your base bevel, and then do ALL your work on the side edge but. By continuously messing with the base bevel, all you lot're really doing is slowly increasing the bevel over time.
A "normal" tune for well-nigh recreational skis would be a .75 or i base of operations bevel and a 2 side bevel. A bulk of us that race or run across ice or hard pack more than than soft snow cull to go with a 3 side bevel for more grip. As far as detuning, it'southward very rarely done on high stop skis anymore equally the shape of current skis just don't require that. If you observe detuning is a necessity, it suggests that your skis may be too long or too potent, there's as well much rotational force in your technique, or you're skiing in the back seat.
Really, with bones tools and a calorie-free hands, it'southward pretty difficult to seriously mess your edges up. Find a shop you trust with your skis then inquire for some guidance - how your skis are currently fix and how to maintain them that style (if you lot like the manner they are now), or what should be changed (if you don't). Most experienced tuning guys are happy to share their noesis (especially if offered a 6-pack of their favorite brew 
).

Thank you for the base communication. I'll go out them alone. What do you do when you lot see mars in the border that involve the base as well as the side? Do you just sharpen the side and get out the dent in there? My oldest has some pretty handsome dents on her edges already.
They say the .5 base bending hither is because of our ice. It's for racers only, merely the coaches say information technology's the "New England" preferred angle, preferred over the ane base of operations bending. Have you always used a .5 base of operations angle?
Just moonstoned two skis tonight. I expect forrard to existence quick about the tuning! Right at present I'm still fairly irksome because I'm wary and careful every bit a newbie.

If the edge is rolled over rather than simply dinged, I'll use an Arkansas or diamond stone (the Arkansas is softer) on the rolled area simply until it'due south back to level with the rest of the expanse. If it's just dinged and still flat I leave information technology alone.
To my cognition, I've never used a .v base bevel. However, the base bevel has nothing to do with water ice grip, it'due south only purpose is to let the ski some wiggle room before hooking up one time on edge. The less base bevel you lot have the more unforgiving and "twitchy" the skis will feel. In general (my theory), mature women prefer the .75 to 1 degree because of both the Q angle and the fact that our ligaments and joints are usually looser than a man's, and then our skis need to "swim" a fleck without instantly engaging or we'd be constantly catching our edges. Again, that's JMHO! As to the "preferred" angle, I'm guessing you lot were discussing junior racers?? In racing, they want the skis to hook upward NOW, thus the .5 angle..
As an aside, either Rick Snell (Fastman) or MSRT did a study a couple of years agone on base angle, slope angle, and speed which was super enlightening. IIRC, on steeper slopes, the minimal base bevels were faster while on flatter slopes, the larger base of operations bevels were faster. The data was really intriguing.

Yes, it is almost certainly junior racing. Interesting info. I'll google for that study you mentioned. Sounds really interesting. Often I wonder how much of all this information is bonafide, how much is folklore, and how much is opinion. Everybody has their stance well-nigh the best way to wax, and they're certain they're style is most effective. So there are the little tuning quirks people believe in, etc. Squeamish to know that somebody really tried to clarify the base of operations edge difference.
I'grand certainly not a racer, and so I hope they didn't requite me a .5 base edge. I'grand still working on stance, weight placement, and getting on edges properly. I was sad to see this morning time come up. Through yesterday I could say, "I didn't start skiing until 2009," and it sounded similar I've been skiing only two years. But, now that it's 2012, it'southward obvious I've been skiing 3 years and I have less of an alibi for being pitiful!
I watched my oldest (11 yo) ski during team exercise this week. I WAS AMAZED!! My trivial (now big, I guess) Georgia built-in daughter is carving with her edges and zipping forth, looking like a pro IMHO! I can't believe she's related to me!

I've been looking online for this blazon of soft SWIX gluey rock and checking with local ski shops. Stopped in at a store today to see if they had them in stock...unfortunately no, simply they were really cool and gave me two 'used' pieces they had in their shop. psyched.
question: practice you wear gloves when tuning to protect your fingers?
