Squaretail, no mater what type of glass you are using, I.E. Woving, Mat or Uni, unless you are using a pre-preg material than it is WET-LAYUP. Since you are usig a epoxy-impregnated wood core, it would be pointless to use a pre-preg.
It is a pet-peave of mine when people talk about ski construction when they dont use the correct terminology.
As for the drill diameter size, using a 3.6 dia bit with the standard screws supplied with adult bindings, that have a 4.1internal dia will increase the chance of interlaminar delamination, and splitting in the core, while there is a slim chance in this happing it is more likely, then if you used a 4.1 bit. Foam coares need a 3.6 to ensure better pull-out strenght, and since foam will give and compress more than wood, the more interferance caused by the smaller hole dia is less of a issue. If you do a pull out test- I would be willing to bet that your data supports this.
grant, I think squaretail may have answered it in post #11.....

I'm not a sales rep, but yes, I am linked to the company. I mainly lurk here, enjoying all the posts and wildy different opinions. I've only posted myself to clear up any specific questions relevant to our gear - and I try to do so in an unbiased manner as possible.
Regarding the shops and warranty, there are very few Mantras out there at retail right now - less than 30 pair, and they're at a small handful of shops. We've communicated to those shops that the 3.6 marking is an error. Mounting with a 4.1 would not void a warranty - quite the opposite, actually. You're more likely to hurt the ski if you try to force the screws through a 3.6 hole in the titanal. Though it will usually work, you can volcano the titanal if you're careless.

Grant, if I may call you that, this is really all much ado about nothing. I think we are getting hung up with my use of the word "wet." If so, I never implied that the woven glass isn't wet. The difference is how the glass gets into the press. In the process I originally called "wet-wrap," strips of fiberglass are literally wrapped around the core assembly before it goes into the press. With the process I referred to as "weaving" the glass is woven into a "sock" that is placed, by, hand, over the core assembly before it goes into the press. It is true that both techniques would be considered "wet."Quote:

All that aside, nice images. If you ever shoot with a Volkl athlete, PM me.
i read this thread and only saw
TAP and INGRID
purely coincidence, I'm assuming.
Old post, old thread, but bumped up recently... and since I'm just watching the heavy rainfall out the window right now instead of working, I'll post:Quote:

Anyone care to clarify?
The wood core skis you've mounted either didn't have a metal sheet that the holes went through or you mounted them incorrectly by using a 3.6 mm bit when you should have used a 4.1 and tap.Quote:

In other news, haven't heard back from the Craigslist guy about the Volkls but will let you know when I do.
Right - should've clarified, my post was confusing -- none of the wood core skis I've mounted with a 3.6 bit had a metal topsheet. What I was asking about was Grant's statement that 3.6 bit should be used only on foam core skis, and the 4.1 bit on all other skis. This contradicts Tognar:Quote:

And thanks on the Volkl info too -- keeping my fingers crossed that it'll come through.
Grant seems to know his shit so that sounds weird.
3.6 is good for skis without metal, either wood or foam cores. 4.1 for metal. Go with what Tognar says.
