Thread: New skis, bases not quite flat

My reason for not trying is because of what Wasatchback is describing - they’re all like that.
If you want to swing by the shop and get their input, maybe take a look at some of the other rustlers on the rack to confirm if they’re similar or not, go ahead. But if you have to send them back and be without skis for some time, I wouldn’t bother.

Ive already stated that a ski does not need to be 100% flat. The edge needs to engage when the skier tells it to.
#2 I already stated that edge bevels should be reset and refinished prior to skiing OR tuning.
#3 Without skiing that ski pictured, you have 0 clue how it skis. Don't care how many Blizzards you've spun!
#4 My G3 Highballs were very very much railed and the degree of unskiablity multiplied w/ surface hardness. Highball is a fully rockered ski btw. So, actually, yes!
#5 I agree w/ your next paragraph, but then again I already stated these things.
#6i never said your "prepping" was wrong. Just that without skiing 1st, you didn't actually know how that pair skied. But I do agree w/ how you approached it. Reset bevels and refinish. Thats just common sense dude
BTW I used to prep G. Stevens demo fleet and worked under the Kastle demo tent @ quite a few demo days.

Oh, and 1 other thing.
I agree most factory tunes suck.
But @ msrp~9hundo to $1k, it's pretty fuckin butch imo to send out a ski that needs more work/$$ to make skiable, other than binding installation.
Also, rockered sections can very much engage the snow surface. There's all types of snow conditions out there. The one in which you describe rockered sections don't matter/engage snow is called 'hardpack' or groomers. Maybe you need to get off the piste a touch further

I knew we'd end here, the ruler is as flat as I can measure.
This is why I stated initially that the photo grabbed the light and made the ruler look bent.
At most, and this is really hard for me to measure, the concavity is 0.15mm - I feel better calling it 0.10mm based on the various pieces of paper I've gotten under it.

Very much appreciating the discussion here.
I see value in all this input!

Over the years i have encountered several new skis that had railed edges. I figured they don't want the edges lower than the base and it is more expense to make them exactly level, so they error on the side of manufacturing them a little high. It you bought them from a store take them back and demand a free grind. If not, you can just flat file them. Come to think of it I believe Volant made their skis with the edges recessed from the bottom a bit
I have also found that it is not unusual for the bases right behind the tips to be concave. Not much you can do about it.Gravity Junkie

I meant nanometer and I stand corrected. Irregardless what we are really dealing with here is 1,000,000 pm of base unflatness ugh the horror
Although on 2nd thought we really should be talking about slope in arc-seconds from ski edge to middle of base. What is the underfoot width of the ski in question

More on flatness, which is more accurately described in terms of slope. For the purposes of this discussion lets talk in terms of arcseconds.
A ski with 102 width underfoot ( i assume thats where the picture in question was taken) at the midpoint is 51mm. If we really want to be accurrate here we should talk about the slope of the bases as having a whopping 395.9 arcseconds of roll. Unacceptable.

These ^^are the same guys in uni that would sit around a table drinking beer giggling and arguing about the square root of pi

New skis, bases not quite flat
Nick at Sunset in Snowmass mall has done good work for me. I’ve taken him my GPO’s and my new Praxis Sluggers (Sluggers were new)
Edit to add: maybe takes both pairs of skis for him to compare?

Last I saw Pi was calculated to over 62.8 Trillion digits. How this has to do with the square root of Pi or the proper base flatness skis I don't know. I'm just a nerd that writes software for the metrology business. At the end of the day, just have fun and ski.

Its ok, engineers don't really have a sense of humor
unless of they are giggling drunk arguing over the square root of piLee Lau - xxx-er is the laziest Asian canuck I know

I know I should use a truebar. We could hammer away on my tools forever.
I'll ski them next week - haven't skied them yet.

Which flavor is best suited for flatness? I imagine the RA on a cashew variety would be high as fuck.

Ha, this ruler is flat, even if it's lucky. I knew knew knew things would devolve into this from the get go.
Anyway, little update from Blizzard. They will only discuss this through a shop, which is super annoying and what I expected.
In light of the company's response, I appreciate the conversation here even more. Thanks for all the input, even it there's been some disagreement.

You already had a response from somebody that works for Blizzard about 28 posts ago. He already told you those would not likely garner a warranty replacement and told you how to proceed.
