So I have noticed a few manufacturers add VDS layers not only above the edge but also between sidewall material and fiberglass (especially on the bottom). Since many of them arent trying to market this as damping, I am assuming it is to reduce delams. Has anyone found this to improve bonding of side...

Is it the white 6661 or have you ever tried the clear 8210?

PM sent for the VDS

"and same composite of course" is exactly the part I missed when I read your first post. I was under the impression that you were saying you increased thickness to compensate for the core material's deflection WITHOUT facings. Thats why I thought you were overlooking the effects of compres...

Like rockaukum alluded to, the core material's contribution to stiffness is pretty minor...the added 20% in facing separation however is major (cubic function). If you want I can always run these numbers through a program I wrote (similar to Bambi's) for this very purpose. I really like the topsheet...

Ok, so I tried to reply to this (but it wouldnt let me): http://skibuilders.com/phpBB2/viewtopic.php?t=3358 Anyway, has anyone ( team08 ?) done some die cutting and have an eye for how fast the die must go for clean cuts? I am thinking of doing a shop press type of setup, but use an air-over-oil 20 ...

Do you have Illustrator? I can't remember if Photoshop can take in a DXF, but Illustrator certainly can. That's how I've always done it, bring it into Illustrator as a DXF, make a white mask out of the shapes, and then rasterize that into something I can use in Photoshop or Illustrator. Thank you! ...

Chris and Montucky, what size batches did you end up ordering from Chemtura? I am being told the min order is 5gal A and 5gal B...a 10gal kit is a pretty pricey test.

So we just use a sloped platform and a regular flush cut bit...but I know a lot of people have tried to come up with a dovetail bit type of solution. Well I stumbled across this while x-mas shopping and thought it might be useful. A butterfly or bowtie bit is also 14deg and based on the numbers give...

Do you mean they have place vds on the base before edging? In the video you can see what looks like black flash, which means the lower cassette does not have a pocket....which means the edges must be pre-attached. How would that work with the VDS in the cyano seam?

I have always wondered what they are doing at 1:47. I cant tell what I am seeing. At 2:19 you can see a red pad installed around the front of the binding area...first mode vibration damping? I would be interested to know what it is and if he notches the sidewall to receive it. I guess it could also ...

I read an article about base material and coefficient of friction. Whats happening when you ski is the friction generated by the wax is heating and melting a thin layer of snow...so you are actually gliding on water. There is a point at which the friction would be too low, the snow would not melt, a...

I like to have the ball of foot (BOF) over the center of the running length. For this reason I tend to use a 50mm setback for boot center, regardless of ski length. But like everyone else has said...it comes down to personal preference and other ski geometry.

Chris, thanks for the details (this is extremely helpful). Your mix has a claimed 7 minute pot life. Does this allow degassing? Or without the extreme preheating, do you find that the pot life is longer?

Chris, thanks for responding. The lf950 data sheet says that the resin and hardener need to be preheated to 150F (66C) and 240F (116C), respectively, before mixing. Then molded at 212 (100C) for 25min. All that before the 16hrs at 212F (100C) demolded post cure. Are you doing the whole process at ro...
