***** URGENT: Need help detuning my Wets *****

[Woos]

Sorry about the crazy title, I just need this info within the next 2-3 hours so I can pick up supplies on the way home (forgot I had the day off tomorrow and want to hit up Granite Peak).

I need to detune my Wets as I've only rode them once and that was just a few small features and mainly trying to get used to riding them. Now I'd like to take them to a few boxes and then eventually some rails/tubes but they definitely need a quick detuning and I'm struggling to find a straightforward reply on what the best way to go about it is.

From my understanding I should clean the edges, take a file and rub it under the bindings and under my boot at a 10 percent angle, and then take a gummy stone to it. Is that it? Should I do multiple 10 percent runs or just one? Do I need to wet it before grinding?

Also is there a specific file and gummy stone I should buy? Does anyone have a picture of their skis before detuning and a picture of what the finished project looks like? Sorry for all the questions, I've never had to detune a ski unnatty before.

EDIT: Not sure if it matters but I will be using these skis on groomers as well. Maybe 10-30 percent of the time depending on the day. I live in Wisconsin so I don't really need another ski for that but I might buy some Kartels or PB&Js later. I can always detune my Wets even more if I were to make them STRICTLY park skis.

so,what I've done is just get a normal file and put it so the file is at a 45 degree angle compared to the base and file your edges like that. A little more angle than this -/. You should see little metal flakes come off and a gummy stone definitely helps but it is not mandatory. Don't think top hard about it, you're just make sharp metal dull. When you detune it don't go to crazy, then just bring your file to the mountain and detune to the feel you want. Don't really worry about getting them to round as there is almost no edge at all for ON3P's park detune underfoot and I have not had an issue at all. Worst case scenario, watch a YouTube video I know those exist.

Wait I'm confused, why would I not worry about getting them too round if the ON3Ps have no edges? Wouldn't my goal be to get them as round as possible in that case? Also from where to where do I do the detuning? Under the foot and bindings or just under the foot?

getting them round while taking off as little edge material is the goal, this allows you to atleast resharpen the edges a little if you need

Find boot center.

Take file.

From +/- 20-25cm from boot center, making filing passes at 30, 45, and 60 degrees. This will create a nice round over. The most important pass is the 30 degree (lowest towards the base of the ski) as you want to get as much edge off of the rail contact as possible.

Make multiple passes moving 2-4" per pass.

Only move the file in one direction. Don't go back and forth in a sawing motion.

Once you are done, making blending passes where you go from sub 30 to over 60 to smooth out the detune.

These passes can be a bit longer and run them all down the edge under everything is smooth and rounded.

Finish touch with Gummi. If all you are doing is Gumming a ski before hitting rails, it's like fighting a bear with a knife. Maybe you get lucky, or are just really good, but you are likely to lose.

Go Ski.

Monitor edge, fix + seal cracks as they form, re-detune as needed, and park skis last a long time.

Even doing all the above, the edge will eventually fail because it's a tiny piece of metal being heated, cooled, and slammed into stronger metal over and over and over with a lot of force. But the above will at least keep the skis alive longer than doing nothing, which is what most people seem to do.

The biggest thing that kills park skis is the freeze (expand) + thaw cycle of water getting in your ski. Cracks will happen and can be managed, but water cannot.

Hope that helps.

All I meant to say was round edges aren’t going to be a big issue. And you just detune where you slide a rail basically just back of heel piece to front of toe piece.

K cool, thanks. Anything else other than detuning that I should do before taking them to rail? I still need to wax them but other than wax and a detune?

I personally detune all-mountain/park skis underfoot at 2 degrees and they never catch on rails but are still semi-sharp. and then i blend it into 1 degree for the rest of the ski.
