Detuning, etc.
Detuning
====== How dull do you make the edges when detuning? I marked & filed the edges of my daughter's board but it didn't seem to help much. I made it so it to visual inspection it doesn't look sharp. It looks slightly rounded, and you can tell the detuned from the tuned part of the edge by inspection. It still feels sharp though. Does it sound like it's dull enough? Last season she rode rental boards, which typically had fairly dull edges. Around the end of season (while her broken wrist was healing), I bought her a lightly used K2 Luna 142 from Ebay. She's had trouble turning it. I detuned a little (3cm into the active edge). I figured start small. Anyway it didn't seem to help much. Detune more of the edge? Make it duller? Sign her up for another lesson? She's about 5'3", and around 100lbs. Weight range of the board is 130lbs. Other stuff ======= My board is on the stiffer side. I can hold it in a wheelie for a max of maybe 2 seconds (I'm sure practice will improve that), but can't get it onto the nose at all. I'm sure being a noob of limited skills has a lot to do with it, but I think a flexier board would help too. If I tried that stuff with my daughter's Luna would I break anything? I exceed the recommended weight range by around 5lbs (plus clothes, boots, etc). Should I just demo a freestyle board to work on that kind of skill? Take a lesson? |

are you sure? 3cm sounds like a ton to me. maybe I'm misunderstanding
you, or you just meant to say 3mm. the board doesn't sound like it's too long for her. I think two things are happening here -- she probably just needs to get more accustomed to it (probably a tiny bit stiffer than she is used to, so the leg muscles need to build up a little more), and the boards she was riding before had NO edge practically. so that's the major difference right there. a lesson might help too.....a lot of resorts have really cheap lessons that last an hour or two. sometimes you can package that with the lift ticket and it's only like $15-20 more. good luck and let us know. and yeah keep that file handy. bri David wrote: Detuning ====== How dull do you make the edges when detuning?

My first guess would be that the board is stiffer also and thus harder to turn. Is her stance comfortable? Boots hanging over the edges, but only slightly? If the board is wide enough such that her boots don't even come up to the edges, she will probably have trouble turning. Os if the boots are hanging over the heelside a lot but inside the toeside edge, she will have a lot of trouble making a toeside turn. I apologize if you already know all this... Mike T |

I think I read it he http://www.firsttracksonline.com/welcome2.htm 3cm was the smaller number, and I though better to start small. Easier to detune further, and to undo. Never done this stuff before though. I was also considering having the edges filed with a 1 degree base angle. Either at the local shop, or maybe I can do it with my pocket file guide. maybe I'm misunderstanding you, or you just meant to say 3mm. the board doesn't sound like it's too long for her.

We were thinking another lesson would be good. When we started we did seperate lessons. In hers the kid who couldn't ride got all the attention (the morning & afternoon lessons each had a seperate one), and the other kids got less instruction. We would probably do a private together. Before we did that, I was hoping we'd each be riding better than at the end of last season. At the end of our second time this season she was almost riding as well as last year. She makes a few turns. At least some of 'em carved. Mostly she rides fakie. Thanks, David |

Is her stance comfortable?
She says so. I think 6/21 & 19" stance width. I might change hers to duck stance though, unless she starts turning more. I would try experimenting with the stance width first, and try going a bit narrower. I use a 19.5" stance and I am 5'10" with long legs! My wife is 5'2" and she goes closer to 17.5". Narrowing the stance will give her more powerful turns at the expense of a little stability. The extra power will help her bend the stiffer board, and the stiffer board gives you back some stability. I thought my Volkl Coal 155 was stiff. As soon as I got used to it (my second day riding it), I fell in love with it. But her K2 Luna 142 feels even stiffer if you just grab it and try to bend it. I guess we should have compared twisting instead. That's just odd, that the Luna is stiffer than the Coal. I've heard good things about the coal in carving-oreinted circles, which generally implies a stiff board among other things. It's a small woman's board, and the weight range is spec'd at 130lbs & below. At 5'3" and a little over 100lbs, I expected it to work well for my daughter. I would expect the same! Also, her board is flat. It has maybe 1 or 2 mm of arch (camber?). Is that enough? Mine has way more. Now *this* is where I immediately get suspicious that the board is either damaged or is just plain worn out. I haven't seen too many boards that weren't damaged or worn out that had less than about half a cm of camber. And, a board that has either lost it's camber or has a damaged core *will* be hard to turn, unless you are quite skilled. You might look for a damaged core by putting the board flat on a hard flat floor, next to you own. The widest points of the board should touch the ground, or very nearly the widest points. If the part of the board at either end that touches the floor is farther towards the center of the board, chances are the core has been compromised and the lamination between the layers has been broken. This won't always be apparent without looking hard, but it can have a devastating effect on a board's performance. I have a board damaged as such, and it's a very nice wall decoration. If you'd like to see what I'm talking about, I'll try to take some pics and post them the web. Mike T |

I was going from memory, but I was wrong. I just measured hers at a hair under 18 1/4". I guess even narrower might help.

I guess we should have compared twisting instead. That's just odd, that the Luna is stiffer than the Coal. I've heard good things about the coal in carving-oreinted circles, which generally implies a stiff board among other things. I was used to sliding turns, but the Coal taught me how to carve, because I couldn't slide it. Now that I've got ths bindings better positioned I can do both, although not as well as I'd like...

From casual inspection, it seems OK, but I'm not certain. It was represented as having been ridden once, and other than slightly rusty edges, it looked brand new. It sure didn't look abused.

Quite sudden, I'm afraid... Gimme a couple of days to take pics. |

i'd suggest you buy your daughter some wrist guards as she's learning to
handle this board! -- jmed |
