Re: Soul Skis

Very cool mod on your ST 600. Grindrite did in fact make a dance for side edge tuning just like what you have made. From what I can find out they are fairly rare to find and I've thought about doing the same thing.

Re: Kiln heating vs. heat blanket

Probably the biggest issue I would see is that you won’t know when your epoxy actually reaches the desired cure temperature. Your air temp will initially be much hotter than the temp inside your lay up. Figuring out how long your it takes for your epoxy to reach the right temp and how long it needs ...

Re: Tip and tail rise

My tip rockers usually rise 55--65mm depending on which mold I'm using and type of ski. tail rise varies depending on the type of ski anywhere 15-40 mm, usually more in the 20-30mm range.

Re: White spots showing through base material.

How much resin did you use and how much pressure ? Since there is no fiberglass between your wood and your base, could it be possible you squeezed out too much? Likely problems Pressure: Too much, too little, or not even Resin too little or kicked too fast, did you wet both surfaces? Poor mold confo...

Re: White spots showing through base material.

Agree, looks like air. Increase your pressure and make sure it’s fairly even.

This material is only produced by one manufacturer. The minimum order quantities are huge for small players.

Re: Flaxfiber sidewall/ sidecut

it looks uniform and relatively normal I think. The only thing I would suggest is more pressure but you are limited by your vac set up.

Re: Nylon over wood veneer - How to do it without bubbles

Try increasing your pressure maybe? I’m pressing at 60 psi.

Re: Vinyl over wood veneer - How to do it without bubbles

By vinyl do you mean clear topsheet or are you using some other material? My process with clear nylon topsheet Apply a fairly heavy coat of epoxy over your veneer with some extra around any inlays. Coat both sides of the veneer. Some veneers really soak up epoxy. Coating both side might prevent dry ...

Re: Thickness profiles

I can't find the document but there are ISO standards for flat area in the mounting area of a ski. I'm not sure what it is specifically anymore, but I do know that it is larger than 100mm. As best as I can recall it varies with the length of the ski and is in the range of what I mentioned. I may hav...

Re: Thickness profiles

I usually create a flat mounting platform between 375 and 300 mm in length. This is usually ~200 -225mm forward of the waist of the ski and ~150-175 mm to the rear of the the waist. I vary this depending on what length ski and or how stiff I'd like the ski to be. I also at times play with the length...
