rjnakata Posted March 16, 2012 Report Share Posted March 16, 2012 (edited) I did a search and found 2 short posts on the subject. Some say emphatically yes, most are silent. Should a carving board be detuned? If so, how much, and where? Thanks! Edited March 16, 2012 by rjnakata clarity Quote Link to comment Share on other sites More sharing options...
lafcadio Posted March 16, 2012 Report Share Posted March 16, 2012 I wouldn't for carving. I think you generally want as much edge as possible. Maybe for powder or a softboot freeride board, but I dunno about that. 'Detuning' sounds like something that's bad for you... like an out of tune guitar or something. :D Quote Link to comment Share on other sites More sharing options...
Chris Houghton Posted March 16, 2012 Report Share Posted March 16, 2012 Yet another personal choice. If you find the nose of the board too grabby or unpredictable when initiating a turn, you could try detuning the first two inches or so of the effective edge with a gummi stone. Just a couple of light passes on the first inch first, then a bit more if you feel it necessary. YMMV. Try it, you might like it. Quote Link to comment Share on other sites More sharing options...
Beckmann AG Posted March 17, 2012 Report Share Posted March 17, 2012 If this is in regards to your 158, then probably not. Often 'de-tuning' is used like interface flex and early rise; as a means of filtering unintentional or outsized inputs from the rider. So long as the base is flat, and there is no 'base erosion' next to the edge, sharp to the contact points should be fine. A torsionally stiff board ridden like a torsionally soft board may feel more 'grabby'. Quote Link to comment Share on other sites More sharing options...
scrutton Posted March 17, 2012 Report Share Posted March 17, 2012 I found this on the SG website regarding it, and posted it on this thread :- http://www.bomberonline.com/VBulletin/showthread.php?36983-Tuning-question Quote Link to comment Share on other sites More sharing options...
tenorman Posted March 17, 2012 Report Share Posted March 17, 2012 (edited) hi RJNAKATA i agree with both CHRIS HOUGHTON and BECKMANN INC. i personally don't detune but i know a lot of experienced carvers that do. i probably do it subconsciously when i sharpen my edges. on the toe edge i will sharpen about a centimeter higher towards the tip and stop filing about a centimeter further from the tail than the other edge. this means that on the heel edge i will stop filing about a centimeter further from the tip and stop filing about a centimeter closer to the tail than the other edge. i am one of the oddballs that feels that you use different parts of the edge when turning toeside or heelside since snowboarders don't stand symmetrically--unless you run parallel angles of exactly 90 degrees on both feet. in other words detune ASYMETRICALLY even if you have a SYMMETRICAL snowboard. so technically the only boards that i don't detune subconsciously are my old asyms. actually a centimeter isn't a whole lot so my best answer is i don't detune. at least not consciously-lol.

KingCrimson Posted March 21, 2012 Report Share Posted March 21, 2012 I slackbelt everything past the widest points until it's round and as thin as possible. I think it's faster. And even if it's not, the fact I think it's faster makes it faster. Quote Link to comment Share on other sites More sharing options...
nekdut Posted March 22, 2012 Report Share Posted March 22, 2012 For free carving, I say no, none at all, especially on on newer designs with decambered tips/tails. Even on "classic" designs like Madds, I didn't find detuning necessary. I'd like as much effective edge on the snow as possible, and only dial things back from there if needed.

Erik J Posted March 22, 2012 Report Share Posted March 22, 2012 I do not detune, but I also wouldn't tune my edge up around the corners into the nose. Quote Link to comment Share on other sites More sharing options...
csquared Posted March 23, 2012 Report Share Posted March 23, 2012 I have been in the habit of detuning for about the last decade and when I forget to do so, it is quite noticeable because I have incidents related to hair-trigger turn initiations. I guess I prefer the board to turn only when I give it firm input. I think this is all about rider preference. I use a gummi stone and 3 light passes at the tip in tail. Each pass is a little longer so that the first inch gets 3 passes, the next two inches get 2, and the last 2 inches get one. I have occasionally detuned assymettrically and this works well on some boards. Quote Link to comment Share on other sites More sharing options...
Jack M Posted March 23, 2012 Report Share Posted March 23, 2012 put your board on your kitchen floor. detune everything in front of the nose contact point that isn't touching the floor. you don't want the upturned nose trying to hook back uphill when your board is tilted up on edge.

www.oldsnowboards.com Posted March 23, 2012 Report Share Posted March 23, 2012 (edited) I like the edges sharp to the contact point. Detune to your preference. You learn your preference by trying different amounts of sharpness at various points along the edge. Just do NOT pick up a file to detune unless you never plan to go sharp again. I can't tell you how many boards I have seen with severe detunes. Someone having rounded the edge back 3-6" from tip or tail. It will use up allot of edge to get it sharp again. A stone or gummy stone is all that is needed. Not aimed at poster but anyone trying to get up the nerve to tune their first board. Learning to tune your own boards is a gift to your self that keeps on giving. Edited March 23, 2012 by www.oldsnowboards.com Quote Link to comment Share on other sites More sharing options...
Pusbag Posted March 27, 2012 Report Share Posted March 27, 2012 I prefer to detune my edges on the slopes. I do not detune with files or gummies just snow. Guess you could detune if edges are grabby but getting used to a sharp board would be a better option. I like my edges sharp enough to scrape your fingernail. Remember in edge we trust.

norm Posted March 28, 2012 Report Share Posted March 28, 2012 I'll second the comments on the post so far, so my comments are; don't waste time tuning it if you are going to detune it anyway - use a gummi not a file - freeriding/carving needs less attention than a race/gate tune - let your riding/feet tell you where your last tune needs improvement, ...... but would add that detuning for ice is more critical than for hero snow, and that I detune less on the nose of the toeside and on the tail of the heelside. Having said that - if you don't believe in asym boards, you might not believe in asym (de)tuning. :) Quote Link to comment Share on other sites More sharing options...
