Re: Anna´s new Slalom

I think a 2-10-2 or even 2-9.5-2 would be better. 150cm is pretty short. I've made 152cm for my daughters and the dims were something like 1.8-10-1.8

Re: Calculating the Radius

Great info! And that clarifies the 80% and 90% calcs. I thought it was saying the tip and tail were 80% and 90% in length which would be pretty long for FIS Racing Ski.

Re: Bamboo/Cork Sidewalls

I don’t think cork sidewall will standup well as a sidewall. I use cork in my skis but it’s encased so it’s not exposed. Depending on how the use the cork, it doesn’t seem like it would hold screws well either. Perhaps using inserts help. But there’s still very light strength in cork. Applying epoxy...

Calculating the Radius

Every so often I like to drive my self nuts looking for THE formula to calculate the radius of a ski. Sno-CadX and BoardCrafter must use different formulas because if you input the same dimensions of a ski into each of the tools they give a different radius. So I searched the web and found a formula...

Re: Section8-titanal

Depending on where you're getting your titanal it should be treated already. Also use VDS rubber on each side, it seems to help in bonding and provides a sheer layer just like for your edges. If you're using a super high grade AL then you'll want to treat it with acid. It will pit the AL which helps...

Re: Snappy or Poppy Skis

There's engineering software to help figure all this out but you still need to build the ski to see how the engineering compares to the real thing. And then its still subjective to a certain degree. What seems poppy, snappy, damp to one person maybe different to another. But don't let is discourage ...

Re: Snappy or Poppy Skis

The million dollar question with a hundred answers. Usually the pop feeling out of a turn comes from camber or the amount of pressure applied during the turn and then released. Titanal is used mostly for damping a ski and torsional rigidity. The pop feeling can also come from CF, the type of wood, t...

Re: Here we go- Another ski press build thread

This is a pretty old post. I remember when this press was built and I think it worked ok. Not sure if the corduroy stretched when the hose was pressurized. I’d be careful pressurizing, do some dry runs to make sure it’s ok before making skis. If you get to 25-30 psi and you have good matching top an...

Re: How to design Ski (shape,sidecut,turn radius,etc)

There's no step by step guide per se. There's many ways and approaches to design and build a ski or snowboard. You can start by downloading SnoCadX (do a search for it) or Boardcrafter for designing. There are tons of videos on YouTube that will give you an idea of what you"re in for. Best option ma...

Re: Pre-treating paulownia or balsa core

Sounds like it’s going to soak in resin either way, pre-soak or not. No idea if this would work but it’s the same idea.... I read in a woodworking mag that if you want to get an even stain over an open grain board like oak, etc. to apply a light coat of wood glue on the end of the board. The end gra...

Re: Section8-titanal

My main goal is to achieve a damp ski that handles like a race ski that's torsional stiff, grips ice well yet bends longitudinally. I made a test piece also, but can't recall the exact size and dimensions, probably 6x12inch. 1/16in ash veneer with flax, .6 titanal, on each side of the ash, bonded wi...

Re: titanal layup help

I made a GS pair. I did a write up on it. My research said the titanal should go against the core. I put VDS on both sides of the titanal, but when I did sample layups with and without VDS both bonded fine. But I went with VDS for insurance and provide a little bit of damping.

Re: woodcore thickness

you can use this spreadsheet that somebody created awhile ago. Its a great help. But I found that it only gives a good starting point because the numbers it gives you wont have a lot of meaning until you make the ski and ski on it. Then the numbers will have meaning because you'll have experience on...
