Re: Round Top skis 19/20

Hi, I am always using a single layer of 300g/m² uni flax directly below the top sheet - this is how bcomp (the manufacturer of the flax fabrics I use) recommends it. It really has a great dampening effect like this. The carbon I am using is differently from ski to ski, but mostly 300g/m³ triax with ...

Re: Round Top skis 19/20

Hi, some things come to my mind regarding the weight: I don't think your skis are heavy regarding their surface area. if you want to use it as touring skis, then yes, they are a bit heavy. You could try to add some lighter wood (e.g. paulownia) to your wood mix. Poplar soaks liquids quite well. In y...

Re: Extra Biax in Tip Area for increased torsional stiffness?

Yes, thats a different way to do this. But what I am wondering: Did some of you do this? If so, did you like the result?

Extra Biax in Tip Area for increased torsional stiffness?

Hello Skibuilders, I am starting to build some pairs for next winter. Mostly, they are very sportive on-piste skis (66mm underfoot, 72mm underfoot, 84mm underfoot). I tested previous builds as well as serveral factory skis on my workbench. One thing I noticed: When taking the foot area as "zero...

Re: Grinding Stone tick marks

When I worked in a ski service, we used a plastic ski wax scraper and ran it over the stone after re-structuring with the diamond. You feel "leftover" stone at once with the scraper, and with modest pressure you can take the "leftover" off. This helped, but it does not guarantee ...

Re: Twisted race ski

Hello Alan, a 1.5mm gap is definitely way too much, especially for a race ski. It seems the one ski is either a faulty production or it was damaged somehow. I would definitely send the skis back to the reseller and get your money back. I am pretty sure Atomic will back up this opinion. I would not t...

Wow - these Skis look really really nice! Did you design the topsheet yourself?

Tape that can stay in laminate?

Hi there, does someone know a tape which is designed to stay in laminates? As my core has quite exactly the width of base + edges (no more than 0.3mm extra), I want to avoid any core shift. Additionally to my well-working system using thumbtacks glued to the base, I would like to tape the core to th...

Re: Achieve extreme edge grip that race skis have

Hi, regarding dampening: This is the part I like most about my selfmade skis. The 300g/m² Flax uni on top works extremely great with the carbon. The skis are "quieter" under foot than all titanal skis I have ridden. They also do not vibrate on ice, they just "slip" more than the ...

Re: Achieve extreme edge grip that race skis have

I compared my self-built skis to the race skis - it is definitely the torsional stiffness that is stronger in the race skis. So, for my next skis, I will add some biax to the carbon triax and see how much that changes. Not sure yet how much additional biax to add (the carbon triax I use contains 200...

Re: Achieve extreme edge grip that race skis have

Hi, I always tune 87/1 (or 3/1). I tune regularly and precise (fine diamond at the end). I have a Völkl GS 183cm and a Völkl GS 193cm race ski to compare to my skis. The short one really is quite like a normal ski and relatively easy to ride. The 193cm is a monster that tires legs very quickly - I w...

Re: Insert chamfering tool

Hi, the one in the picture has many cutting edges - they do not perform well in wood and chop it. I'd go for one with 2 or 3 cutting edges only - they work well enouth in both wood and metal in my experience. I have one with 3 edges and it works both wood and metal very smooth.

Achieve extreme edge grip that race skis have

Hi, I am about to build another piste ski - it will be 74mm underfoot, 182cm long, 17,5m radius (ash core, 2,5 - 15 - 2,5 profile, 300g/m² triax carbon below and above core, 300g/m² uni flax on top) I am very satisfied how my piste skis carve and drift. The only thing I miss that factory race skis h...
